The Safety Episode - How to not die working on a CRT

[Music] [Music] [Music] well good morning good morning good afternoon good evening wherever you are joining me from today it is Monday October 2nd here where I live and it is time for another episode of the bunker so welcome in everybody good to see a lot of you already here in the chat see a couple people have showed up early I appreciate that we got some people showing up now and that's awesome um I expect maybe we'll have a few more people showing up today or maybe some people that have took a a couple of episodes off we'll be here live today I'm anticipating with with this topic right this is I kind of posted it out there that this is like one of the almost uh forbidden topics to talk about out there so yeah we're going to be talking about safety CRT safety and I'm going to give you the rundown on that here in a second but first thank you all for joining me again live here on YouTube and this is the bunker and please if you don't mind I would really appreciate it if you could hit the like button for me uh right on your browser or whatever form of medium you are watching this on if you are able to please do so uh it does help the channel and this show get more people coming in cuz where I live this is like H when I was in college we would always laugh and watch like the Mory poic show uh the mor poit show during this time block right this almost noon or like what's his name what I can't I remember Jerry Springer so it's like this hard to get hard to get a lot of people on time zone here in the middle of the day in the United States but if you're out there and you can drop a like it definitely helps I really app appreciate it thank you so much thank you everybody again for being here so we got reron showed up today awesome thank you for coming Temple of CES hat or seat or seshat I'm sorry I'm terrible with the name sometime good morning good morning am mean Amino amimo Alexander Seb pido padello Giants mega cards thank you all for showing up Snuffer stuffer welcome in welcome back thank you all so again today we're talking about CRT safety and uh we're going to let things go for a minute that's generally the procedure here and so if you're showing up and watching this after we are live uh feel free to check out a pinned comment below it will tell you a timestamp a timestamp in uh the bottom of here where you can just jump ahead past like the warm-up period because it just does generally oh excuse me generally takes 15 minutes for people to show up at least the majority of the crowd oh so welcome in wonderful Monday wonderful Monday we got more people coming in thank you all so much and yes uh when I will be open here's the thing when we get into the safety discussion it's going to be like this we're I figure it's been enough time that uh I need to probably make an updated uh safety video and it's not going to be this stream is not a representation of that entire topic cuz um there's a couple things I want to accomplish today first off I want to go back and review the tape and uh we've done that here before we want to review the tape and see the past episode that I have on safety which I'm looking at and it says goodness gracious it's four over four years old uh October 24th of 2018 so we're coming up on the 5year anniversary which is this hilarious so we'll get to see mid-30s young spry Steve in the old shop in Tennessee uh we'll get to see some footage we'll see what mistakes I made and uh where I got things wrong and uh cuz I'm sure I did I mean this was five years ago folks and between now and then I've probably serviced a good five years I bet I've serviced a good 800 to almost a thousand CRTs right my CRT body count is pretty enormous at this point morning Travis and clash and Robert leppy Kevin Shane thank you and uh hey good call I I know I think it was you stuffer stuffer did you caught that first off thank you anybody who watched the new video that came out last Friday I know a lot of people probably did because it got one of 10 uh over the weekend for me so that's awesome thank you so much and uh I think it was you Snuffer stuffer who caught the uh creepy uh creepy transition I put in there in that in that first transition uh of that video so if you don't know what I'm talking about it happens happens early 30 seconds or so in so anyway uh yeah hang on guys I will'll be open up the questions in a little bit once we get into that topic so just hold tight cuz I don't want your topic you may have a great question I don't want it to get barried in uh in our you know getg going discussion okay so let's uh let's get in here and as things are going oh let's see what's been going on so I had that video come out with the two uh sonies the two 8 in kind of a comparison quick video I think it was really enjoyed by a lot of people so maybe I'll go through through and do a couple more I have another set that I can hopefully do another that style video uh but of course look this uh we're still working on promoting the Music City multicon which if you want more information on it I just I would consider just Googling Music City multicon it's in the Nashville Tennessee area it's at the end of this month right before Halloween it's that weekend Friday to Sunday I will be there I will have um I've been thinking about what I'm going to do more and more and more we went through this uh my presentation in one of the episodes here on the channel a live show and I was talking about things I wanted to change and so there's going to be some things obviously I've been thinking on like that but I'm also bringing some CRTs I have a lot of extra consumer CRTs that are in great shape that I just have no use for I've got a few of them and I'm going to be done with them and I'm going to take them to the show to sell them and it's going to be reasonably priced I mean it's not going to be like $10 but they're going to be decent good working CRTs so you're probably looking like 75 bucks for something I'm going to open it up clean it out and I may even offer something whoa Cole what's up sorry Cole is getting all feisty back here come here what's up buddy he's just over there barking at something like what I've been moving some like I said I moved some CRTs out to uh make a little room for you're a good boy to make a little room for things I got all these extra CRTs so I'm going to be taking some of them to that Music City multic content hopefully I'll float them to people who need some like 13 in and I'm going to have one 12 in that I'll bring that' be pretty nice that one will have like component and everything cuz I got an extra that I just don't need anymore so again again if you're going to be at the Music City multicon I will love to see you there I'll have a booth there I'll be working on CRTs I've got a plan uh you can come by and see me work on some crazy CRT stuff live in a booth I'm going to put up like some caution tape so nobody gets too close but other than that I'll be there and I hope to see a lot of you there so Cole gets kind of upset when you move things out of place and it could be something like a basket or a ball or something if it's in a place he doesn't think it should be in he'll get mad and bark at it and and just like think like it's an evil evil something so I also have uh on the safety topic I have equipment here I want to talk to you guys some more about it you know of course we have this guy which is our lovely discharge tool and um other very minor tooling I have a CRT right here that's popped open it doesn't have any power into it but it will make for a good demonstration on the desktop here where I should be able to pull this camera over and uh you know we'll be able to look at some things there uh when we are when we're ready to do that just take a look at Co Cole he finally calmed down and got in his bed over there so that's good sign he may be snoring everybody but you know the you know the drill we'll let him snore I'm sorry if that happen so we'll we'll just keep an ear out for him there is a filter on the camera but again thank you everybody for showing up and I'm been just a little bit of stallin really I did get to go to a college football game again over the weekend had incredible time my team won uh I made a fool of myself probably and uh had a good weekend so um that was all good and now so let's just go let me see let me see if there's anything else to really mention uh I will tell you a little bit of a story about the video uh that that we just that I just came out with again um I will tell you a little bit behind the scenes this this those two CRTs had to be shipped okay we got a good size crowd here there two RC there two CRTs had to be shipped all the way across the country and I had to put them in the same box and I'm in Virginia and I had to ship them to Tacoma Washington all the way from the east coast to the West Coast and I uh was talking with the client and we decided to go for the air hey Amos thanks for coming today good maky uh Shane thank you guys anyway I did this shipping procedure and of course I packed these two things wonderfully but I packed them in the same box and and it was a pretty good siiz box it's like the same size box you'd pack a good 13-in and but instead I packed two those two smaller ones I packed them really well packed them in a box and then put them inside another box suspended in bubble wrap and then sent them air and again it was a good siiz box it weighed 40 lbs 392 actually on the scale and man oh my goodness it was $576 just to Airship it 2day air from here to there with I put on it I think $1,400 in coverage for insurance but that's how much it costs that doesn't include the packing fees took two days to get there and if you go and you watch that video I do show how there's a speaker inside of the kv8 ad2 I opened it up in that video and I even show you where the speaker is because I go in and show there's a potentiometer back there there's a connection point where that speaker just plugs into the circuit board well in that air even in the air travel it some somehow the package bounced hard enough where that speaker uh tension was on that wire cuz there's a lot of tension on it I mean it didn't have very much place to give so the bounce was enough to dislodge it believe it or not from the board and there was no audio so I had to guide Tony he was awesome I had to guide him uh kind of through old reference videos as well as well through DMs on opening the setup and looking in and thankfully yes enough it was just the speaker become unplugged because he was testing the set everything was working good it just didn't have um the speaker plugged in so there was no audio so thankfully he plugged it back in it worked fine he was able to get it back together and everything worked perfectly and when it came to the other set which both these again I said went to the same spot it was the 8044 Q you know you get it in and those just are tricky when you use the buttons so just take your time using the buttons on setting up that CRT fre inputs because it's got a lot different button combinations you can push and if you don't have the right ones it'll look like the screen's messed up and it just needs to have the right combination press so you have the correct input correct settings everything like that so yeah it's it was still fearful I packaged it so well but it doesn't really matter you're always scared oh goodness all right all right thank you sashen I see your comment excellent congratulations on fixing things all right so that happened and that was fun over the weekend and that's just a follow up to that video um but hey let's start talking about let's start talking about safety right okay so uh this is the time when I'm going to go through some things and then there will be a section here in a minute where I'm going to open it up for questions and comments CU as I said I want to make an updated video it's been long enough uh to do a simple chat and make it about safety so we're going to look back at the old footage but um not only that I wanted to open this up as a discussion so that we could talk about it together because there going to be things that I'm going to forget to mention in that video cuz I'm a person who works by myself it's going to be something extremely um like basic and then I'll just get you know I'll just get hated on for a simple mistake that I shouldn't have made so that way I can um kind of work through that with you and we can talk about it and hopefully I won't forget anything okay so let's uh let's begin let's first off man I'm going to just ladies and gentlemen I'm going to just talk to you now we're in our main topic okay so this is it right this is going to be the time stamp moment my clock on the counter says 16 minutes and 49 seconds so this is the point we're jumping into our main subject safety and our full topic here we're going to start off by of course me plugging one more time because we have new people in here please hit the like button if you can every time you hit the like button it results in 8 to 10 new views of this show and that's really helpful and I always appreciate that everybody who does hit the like button you do a lot on this show and I love it I thank you and that's really it's really helpful right now as this is a new live show anyway let's start off by talking about a couple of tools okay and really the most infamous tool is going to be this this lovely device right here it's a discharge tool and this is a homemade discharge tool I made a video on how I made this thing goodness gracious so long ago I can't even remember that either that's the same time period so what I'm going to do is we're going to hopefully jump over here maybe I can get a closer view of this thing for you and take a good look at what what I've got here because this is nothing like what's it called you know there's nothing there's not a lot of not a lot going on to this tool right it's pretty simple you can go a little bit deeper and there's professional versions of this that you can buy for a lot of money [Music] right well of course Bob why do you think it's got so much oil on it probably broken into a few uh I've probably had to hot wire my Mercury Grand Marquee a few times with this tool okay so this is one of uh one of our safety weapons probably our most important safety weapon and you need to be you need to be comfortable with this thing you need to be confident with this thing and it does look terrible right but there's there's really a reason for all this there's really oh yeah allegedly you're right you're right folks this is not this is nothing about um not being actually thank you Bob for showing up I can finally remember to put you on as a moderator here from my phone and uh I don't want to hear myself you need to be confident with this thing it does look terrible excellent there you go so let's let me do one thing really quickly here and there we [Music] go all right there we go all right folks so as I'm saying here we've got our discharge tool okay it's pretty simple it's a standard what what is this we'll even look at you can look at this a husky version it's an old old um flathead screwdriver pretty thick thickheaded right see there see I don't know how good that back up there a little bit like right there okay pretty thickheaded right I mean you want me to pull out the caliper and show you I like to use a thick one [Music] okay right that sounds good I used I like to the ones with them them thick thick shafts this is this is just so childish I feel like sometimes so this is I would turn that on but it's busted it's not been working right you know was that about 10 whoops 10 mm 10 mm wide and uh oh heavy duty goodness gracious there we go live show folks yeah the thickest point there and again pretty thick thick thicken end here and just just like that now I don't what I don't want on here is a very sharp edge okay I want this to be dull and blunt and I don't because I don't want to go in there and and we're going to I'm going to show you that here in a second but like for example if I'm over here and I'm using this I don't want this to be now this is a bad one cuz it's actually got I'll show you you got this stupid um cap with watch I people get upset I'll shock myself on the safety episode anyway it's got a cap here that I'm that uh I'm going to have to try to remove here live for you we'll do that I'll show you this um you know and this is actually not even recommended for Sony Sony doesn't want you to discharge it the way we're going to do it but anyway you don't want something too sharp of an edge so when you when you get under that cap and you're actually discharging it you don't want to be like scratching into the glass right there or you don't want to accidentally slash this rubber anode cap and make a hole in it where you would expose that voltage what's up retrotech or die so there's no um again we'll get this off in a second but there's no reason to use something super sharp and also it doesn't need to be like super long I mean it can be longer than this if you want but it doesn't need to be like example this long okay okay usually you could use it like this long but then you need to be concerned with shielding all this because you're going to take this and make this a big live uh voltage probe for the most part so you're going to have voltage going along the metal here so I don't like to make it hugely large when I'm using it I also want to use something that has obviously no conduct no conductivity chance there's no voltage going to pass through this handle at all there's absolutely zero chance of that right it's in a it's in an acrylic plastic molded handle that has no chance of transmitting or transferring any type of electricity okay so that's the first thing too that we need is we need to have the dull tip needs to be pretty heavyduty and thick and then uh or these are just the tips I would tell you the tips on this tool and then nice a nice handle like this you could use wooden handle ones just as long as it doesn't like see how that insert in there is the metal from the edge here the only thing I will warn you about is if you have another one where that metal comes out in any way if there's a ring on here that has the metal and it's it's you know it's part of your screwdriver that's bad or if that sometimes I'll have screwdrivers where that metal will go all the way back to the back here and then there's an exposed piece of metal back here and that would be just as bad you know you're going to be really being risk risky there so the structure is that you start with a cheap decent screwdriver and then what I have here is just an old piece of scrap wire from a busted extension cable and the reason I use that is because it's it's well shielded first off it's high high gauge wire we'll clip a piece off here and then look at it a little bit closer so if we you know see here you know you're looking at I don't know maybe 10 to 12 gauge wire here I don't know maybe well maybe not quite that maybe maybe in that 12 to 14 category is better but it's well shielded it's a piece of scrap wire nice copper in in there and since it was an extension cable it had three things you know a positive a neutral and a ground and these don't do anything but it also has an extra layer of shielding out here that's why I like it is I have this extra layer of shielding and if we look in here that has an exposed uh or that wire goes up to that point and then it wraps around it's not soldered on there it's just stripped down about 2 in and then it's wrapped around this and um then that cable goes down here and then that cable comes out there where it's got tons of electrical tape and then again this is just scrap wire that's left over and that goes down here to the other end which this is not hugely long again you don't need something that's like 4 foot long I think this one is about 3T which is about as much as you need you know and on the other end I actually did solder in a a I clipped it in I soldered it in it's a nice little alligator roach clip whatever you want to call that thing and that makes for a great clip to clip on to something like that and then there you go so I'm going to show you a quick test for your tool let's say you got it together and you're like yeah I feel pretty good about this thing right this tools pretty pretty good I feel pretty pretty you know as Larry David would say pretty good pretty pretty good this is braided wire I don't I don't use solid core cuz I the solid core would be too stiff too stiff all right solid core be very hard to bend like you want it to be able to roll up like this see how I can roll that up and maintain a good high quality cable but let's say you got it all built together and you want to be safe right so safety so we want to make sure we we have this thing tested and we're not going to we're not going to expose ourselves to any danger so all you need it doesn't have to be this big fancy thing okay it doesn't have to be a big fancy meter like this one I'm not trying to my fluke Flex right not fluke flexing on you sorry I just love this meter okay give me a break just kidding I'm joking all right I'm in continuity mode and I'm going to stop confusing you and me and I'm going to flip this camera around okay give me one second I think one more is the good one excellent there we go there we go folks ladies and gentlemen we have we'll fix it up a little bit better here so all right I've got just you know this is in continuity mode it's ohms mode right ohms yeah okay so all we're doing is we want to make sure that basically what's going to happen here is that our voltage when it goes from one point it's going to go to there right right so that's good that's a nice consistent spot where that's all we want to do is if there is any voltage in that anot cap it's going to hit that and we want it it's going to quickly go to this Edge and it's going to just discharge out into the uh wonderful atmosphere okay I'm just kidding it's going to discour it's going to discharge through the ground on the TV uh but we can also do something like this like I can maintain this clip here which which we know is again live to this end so that's a demonstration if we had for examp if we had for example this uh right here like this would be live right voltage if it was if it was actually voltage coming in we want to check and see see so like I'm I'm testing the edge here where my tape is I want to make sure I don't hear anything like even over here see I want to make sure that oh see there's a possibility for me to you know catch that voltage coming out of any of this it's got to be just you know this is again a way to make sure that there's no voltage coming anywhere you got a piece of metal here to probably do it where you would have that okay see so this way you know you're safe like okay well voltage it comes in here it's going to hit that if it happens if it happens it'll go there it'll go to that point and and I'm completely safe touching this end okay it's always great to stay below this point right here no matter what but even like this exposed in it's not like that's got any connection point to this right okay see none of that voltage is like come to that or anything usually I have that clipped off I just had that I have that clipped off pinched off cuz it's not even being used well I've have good I've all right so you guys do know uh that I have seen one time a really bad CRT discharge that I could show on on the on the stream really well arcade monitors do it a lot hey Tony I was talking about you earlier thank you for showing up and so I'm sorry I lost track of what I was saying there but anyway we're not we're not worried about this point here it's again just this black cable that's going to this clip and I have that pushed up over there and you just maintain a good safe distance you wouldn't go any near this with that plugin going in right there the Toshiba yes I'm sorry that's what I was mentioning thank you for the reminder sashen the Toshiba video I did a couple months back on the channel it had a great example of uh no it's okay it's it had a great example of a discharge where I would every time I would discharge the thing it would make a huge scary zap and you could almost the interesting thing was me show you kind of now this will probably get a little bit dizzy right let's see uh we're probably I'm probably going to have to without making you guys too sick here let me go back to this I'm going to fix that camera um if I can here whoops sorry about that so let's uh get back here go back here and we will configure the video again and I'll invert myself back to normal okay now when you have a CRT like this Sony's pretty much always have a built-in bleeder resistor and most high-end stuff will but you can never really take that for granted especially like guys this is G this is like highle you know I obviously I'm at a point where I have done this so many times I'm comfortable I know which ones to work around like this but most of you are not going to have that level of an experience so I don't want you to go in here and take anything for granted hey Robert thank you very much for the Super Chat says I love your channel keep up the good work thank you so much I appreciate that so again you can go see that video that Toshiba video and it will show you one of the worst zaps you'll ever see uh on the on the CR te just zap every single time on the end of this and where if you were touching that it would go into your body it would definitely make your day unpleasant definitely make your day unpleasant so this I'm going to be honest with you this thing right here I don't know how bad that let's get that just the light off there we'll leave that up there this right here is pretty much the biggest tool like that you have to worry about when you're working on a CR just to be safe you need um you need to have that consideration for safety uh and you need to use this to make sure things are safe so let's talk about uh maybe well how about this let's jump over now let's roll some footage we talked a little bit more in depth about this tool we're going to see what I have to say we're going to see what a much younger much more spry Steve has to say about all of this and I have two videos I don't think we're going to I don't think I can handle watching both of them of myself to be honest oh but pardon me folks so let's go back let's go back in time back to a time when I was much younger much more spry much much much much different we had a different dog in the house yes I don't know if Brutus is in this video but we're going to roll through this Bean footage here and we're going to see we're going to see what uh what this younger Steve from retr Tech has to say again this is five years ago I'm going to pause our Jazz obviously I'm going to turn I'm going to turn my mic down a little bit I'm going to turn desktop Steve up and let's watch this awkward entrance oh my goodness like this is this is going to be great let's let's do a reaction all right hang on hang on I know I'm not let's try now I'm Steve and today we're looking at CRTs again today we're going to be talking about CRT safety specifically on a CRT that is a consumer grade television so lastly I want to see if this is a good television to possibly RGB mod it only has RF and composite inputs right now so it would be a great candidate if it's possible to add RGB to this so then it's not so uh useless pretty much in today's world okay so let's take a closer look behind the CRT before we open it up this is just a brief look at the behind the right this poor this poor awkward Steve ma'am this is [Laughter] hard this Steve this Steve was lacking a lot of camera camera Charisma I will admit oh goodness gracious let's see what on this specific one txd 1972 manufactured in January of 1997 and Samsung and like I say the inputs down here on the back are very standard um actually it's only got a one of the composite video uh connectors looks like it's been ripped out of it and then we just have the RF and then there's composite and mono audio in the front so let's go ahead and remove the shell now and take a look in the back all right so before we go too much further let's just talk about something that we need to make sure we've done first off make sure you've unplugged the television and uh this thing was turned on yesterday so it's been full 24 hours since it's been turned on I I just recommend waiting about a day all right this is hilarious right okay let's already debunk this old this old youngster oh goodness let's just debunk this youngster for a second first off it doesn't really matter most of the time to wait if you do this right even if there's a even if there is energy in there you do it correctly you discharge it correctly can do it 20 seconds after you unplug the machine okay now I would recommend waiting a couple minutes just because you do hear a lot of that voltage kind of sporadically separated out the tube when you turn something off and of course you want to let all those circuits if they do have a discharge circuit to go you don't need to wait a full a full day I know I hey guys I loved I I'm having fun I'm not like I I thought this was going to be fun I haven't watched this video probably since I made it so hey Belmont thanks for showing up today um hey Brian Armen Ronnie cousin Hubert thank you all for showing up today Ronnie I think I got you yeah Chris oh I know right Felipe all right let's continue let's continue to move on down the road and and I'm also going to give you an update to this television we actually did a stream I did a stream with Bob what last week on this TV this is the red one for the first uh time you open the red one that was RGB modded you know if you've never opened it before it's always good to just unplug it and let it sit for a full day okay I've removed the back of the TV now this is again the very first time I've opened this television and you can see right away this is just filthy it's covered in all kinds of dust and just sediment from from probably 20 years sitting being opened I hope you can see on the camera but there's just inches of dust and buildup on here so this is a really good example of what I wanted to show on the back of a CRT and the reason behind opening this even if you're not doing anything else it's good to come in here and inspect I there's so much dust on this board down here that if you were to use this for a long time you would probably heat up these components this dust would uh probably cause something to either fail um it could burn up and stink a lot so this is a perfect example of why you'd want to get in here in the first place to clean out the CRT but before we do that we want to make sure we go through the safety precautions and we do the right things to make sure we're safe okay so as you can see like I said just tons of filthy dirt and dust I really want to clean that off and uh so before I go ahead and do that I want to make sure this is just completely safe and to do that I need to discharge the CRT now uh some people you know say you don't really need to do this but let's just go ahead and do it to be safe on this let's just assume this is the very first time we've ever gotten inside a CRT so let's go ahead and discharge this and uh before we do that though let's talk about a little bit of personal protective equipment there is some personal protective equip all right so here here's the thing I remember this let me get here we're going to get a little personal here okay first off thank you everybody for showing up look if you're here I'm sure there's people here that are new for the first time welcome in thank you very much for showing up I really appreciate it this is the bunker it's a live show it's every Monday it's at this time slot and it's about every Thursday sometimes I have to take a Thursday off and when that happens I have a replacement show that that fills this spot that I shoot with a friend of mine named ZZ called the cathod r podcast so uh but anyway welcome in thank you so much for coming please if you don't mind if you just got in do me a favor hit that like button that does help the show grow and I'm sorry if you've heard me say that already a few times and you've already done it I appreciate it but I do have to mention that every once in a while and again we're talking about safety today we're looking at this old video and yeah these are the gloves right the infamous gloves okay I'm about to show you the loves on this video but the reason it was really weird you know this is a time when I didn't uh I didn't know a lot about CRTs not nearly as much as I do know now right I didn't know I I wish I no I wish I knew them what I do know now exact opposite of the Toby Keith song uh I wish I knew then what I did know now okay and that's that these aren't really necessary and oh I was really just more concerned with how bad people would uh judge me I think if I came out and said you could just do this without gloves now these gloves are okay they'll give you a little bit of confidence but they're awkward look at them you cannot precisely touch anything they're like some kind of just messy glove just some kind of glove that you can't awkwardly precise L touch anything right what am I supposed to do with Precision with these big sausage glove fingers okay and these are gloves are expensive right get them from Granger see see what this says uh we're going to look at this in a second but these are merry gold industrial grade 10 score but they only do Max volt 500 ac voltage protection so you're pretty you're pretty much fine for doing like this like your hair oh my hair like if this is on and you're like oh my hand just fell against it right and I'm not trying to like that's really what your protection is this is has such high voltage if it was running it really wouldn't this isn't going to be enough protection if it were to hit this high voltage running a sorry just losing it there for a second with this freaking prop glove anyway uh the glove is awkward right cuz if you're in here you're like o I need to do this need to do this need to do this this is all lower voltage stuff but there are areas of high voltage in here right anyway I wanted to go off a little bit about that because again we've already the good thing what what's the good thing Steve or young Steve here said so far right we need to be unplugged we need to have the discharge tool and that's the best things that he said so far he said some stupid stuff but we do need we do need to be unplugged do need to be unplugged but if we're unplugged right there's not live voltage going in there so it's just stored V voltage in that tube now this is important the larger the tube the larger the voltage so if you are working on a large tube Steve's advice about waiting a day isn't actually that bad but you don't have to do it because there's plenty of large arcade tubes that are like 30 in right and you can hey I need to pull that board it's just been not working I just tested it you could pop it off and it will probably zap okay you could use this but you don't have to okay so we're going to look at what C says more about these gloves and kind kind of giggle um kind of giggle at ourselves so we'll see what youngster Steve here has to say continue on Venture lesson on personal protective equipment young Steve equipments you can use while working with electronics first example would be gloves and these are some highly rated uh industrial strength electrical gloves uh rubber insulated gloves I'll show them off here these did come from Granger and they were about $70 but they're available through any um they're available through any store that may sell safety equipment online so Amazon eBay all places like that will have something like this but these are specially made and they're not hugely thick but they do feel weird they're a specific type of rubber and they are rated up to a certain voltage and so this is a good set right here again these were about $70 us for these gloves after all the uh discounts I got for ordering them so what you can do is actually wear these gloves and then it's recommended to even go further than that and these were just about a $20 pair of uh nice leather gloves and I you can actually put these on the outside of the red rubber gloves and then you have double protection for your hands and when you're sticking it inside a CRT if if you just need the extra um you know if if this helps you get over any kind of fear and makes you feel so more secure then please don't uh you know please go for it it's not it's not that bad if you're oh my goodness yeah young Steve Young Steve this is so comfortable hilarious I have them still here look at them they're nice and dirty look at this this is double bag baby this is like this is like better than like '90s Trojan ads Right double you got to double it up guys you going to spring break this year you go you going to Club lavila oh you must be preing you must be pecking double stack it all right like I said man my CRT body count now has got to be over a thousand oh man people get like oh if you don't like goofy stupid I don't know jokes like this you're in the wrong place I guess right [Laughter] so oh look at this you keep going young man over your fears um then I say you know it's always better to be safe than sorry another thing to think about is the kind of clothing you're wearing while you're working on this stuff if you want to be um protected additionally it's good to wear some you know tight sleeves now I'm not saying this cotton material is perfect it would be nice to have something that was maybe a little thicker in canvas so something that's tight on your arm under that glove and at least something that will uh protect your skin from direct contact on something that can help out too always too when you have your hand inside a TV if or any other electronics that has power going into it only work with one arm or hand at a time uh keep the other hand in your pocket it's called the oneand pocket rule so just use your work hand and keep your other hand in your pocket while you're doing the work and that way you're never going to ground something through your chest area uh which can really cause damage to your heart all right good good job there young man you got through it oh goodness yeah sorry guys I I did get a little bit funny there for a second Belmont thank you oh goodness yeah let's hope I don't embarrass myself too bad oh goodness this is so fun anyway uh the one-handed rule is a great piece of advice when you're working on discharging a CRT it always is good to have one hand free from the frame so if you're sitting there like let's let's say let's say Stevie retro is in here and he's like oh hey hey hey I'm about to discharge this where should I hook this up um let's plug it to the chassis here right and then let's go in here and let's discharge it all right I'm ready I I've been uh I've been training I've been watching myself I'm ready to discharge it and I come in here and I discharge it right and I'm like ah let's make sure let's see if I'm right maybe I'm crazy maybe I'm crazy but would would we have shocked oursel by doing it like that right oh my goodness look at that we could have been so careless we could have just like Zapped ourselves by holding it like that right so you want to have that one hand out of the way so you don't actually do that and it's actually really great talk about the Shocker haven't thought about that since since bad days in college all right so one hand in the pocket that's really a great piece of advice right we want to have one in the pocket some of these things are definitely going to stay in the next video for safety and that's one of them what else um well the reason to is if I did what I just did on this example and think about how that path of voltage would go it would [Music] go well it would go through there would hit here go through here and it might try to jump through this but it wouldn't jump through that but it's going to just go throughout your body and everything and you don't want to take that like to your heart now another thing is if you hit two points and you do like this and you close a circuit that's even worse right that's when it passes through your heart and hits a ground something like this and you're like bam and it's like don't want to do that at all that's a really bad thing so anyway that's a fun little demonstration on how you could accidentally zap yourself just by your form on uh discharge also think about that if this is a live set with metal chassis this has a metal chassis frame and it's on a ground Loop and if you have have a metal based table well you could ground through the table then you have even more um if I wanted to get extra frisky and protected I could for example take my uh ground wrist strap here that this like my ground wrist strap actually goes all the way to like The house's ground cable like a big Rod so it just literally goes into the Earth from this directly so I could you know I don't know I could if I wanted to I could connect I don't even see one really handy I usually have these things within Arms Reach um but I could pretty much run a jumper cable from this point to this point and that way it would go off into the ground okay hey Grail thank you for showing up so that way I could that just get that on out of here or you could leave it on the frame but you want to make sure you don't have the frame attached to something else that's metal you know you could then transmit it hey that's the hey this is another this thank you for bringing this up Belmont you don't have you can have fun you can just watch this show laugh at me we can laugh at old Steve you don't have to do any of this stuff I'm not telling you to do any of this stuff I'm just trying to show you a little bit of what I do when I do this stuff because if you do not have confidence or skills or much technique you shouldn't really try this if you don't want I mean there's always going to be a risk when you're messing with electrical stuff thankfully you could take a lot of the risk out by unplugging it but even in that case there's so much risk because there's electricity stored in some tubes uh Beyond some of them going stay charged for a long time that Toshi would stay charged for a long time okay so if you're not comfortable at all that's perfectly fine and don't uh uh you know know your limitations take time there's no there's no like there's no race here there's no race to a Finish Line most of the time take your time uh if you want to learn about this stuff don't have to do it right away I'm I'm and this is like it's just firstand a little bit sneak peek I would love this to happen someday to have you know a like a master class offering where someone could come in Live or a classroom live where you would have to basically pay for like a three-day course right where you we hang out you bring a CRT with you that you want to work on you bring a certain set of tools and we're going to get you to a certain point from day one to day three and it's like a whole Workshop might even be like a weekl long thing I don't know I mean it would have to be I'll be honest with you it would have to be something that would be in price line with other kind of camps like that that better specialty I don't know what that exactly would cost you know but you would have to think about it being something that would be along those lines and again this is just this is just brain farts coming out here on a live stream with everybody anyway sorry for that jump off here um but I appreciate everybody coming in and and like kind of guiding this conversation as we go cuz there are some key things coming in there uh but let's get back to some humor and and see what see what we have to say from young man Steve now I will give you a background at this point I believe I was still using some kind of editor on my phone maybe or maybe that's I'm trying to figure out if I was filming with my old cell phone at this point or if I had moved on to my original film camera that wasn't a cell phone and that was a Nikon camera [Laughter] Grail I would have the Texas is a place if it wasn't so hot it would be a great place for me to go there's a lot of business there and I have a lot of good connections with with people in the Houston area uh so that would have there's always that if I really gosh man anyway Let's uh let's move on back here behind the CRT look at this uh Spring right here this is part of our ground loop on the CRT and this right here is our degos coil cable but this one is directly attached to the ground loop on the entire CRT television so that's where I'm going to connect my end of my discharge cable is probably right in that Loop connection area or over here um on the cable that way I have a good spot just easy to connect to the ground of the whole TV now I've gotten my discharge tool and it's connected over here to the ground spot I told you about and for today's demonstration I am going to wear the gloves so what you're going to try to do now is just take the end of your discharge tool um which will then send the electricity from anything that's built up in that tube over to the ground and you should uh you know just maybe sometimes you hear a pop maybe we'll be lucky and we'll hear a pop when we do this but not always so I don't even mind flipping that up so you can actually see the anode but I'm I'm I'm physically touching it a couple times now that I've touched it I can let it sit for 5 minutes and I'll come back and repeat the process okay so it's been about 15 minutes I've come back here and I'm going to go ahead and do this all right so just like I said said earlier this whole double discharge it's not really necessary what you could do instead so you could skip this double discharge you could pop it out and then there is a chance that the tube itself this happens sometimes especially with larger tubes okay I'm not going to act like it doesn't because it does sometimes this tube you'll discharge it once and then you let it sit for a couple minutes in a secondary amount of electricity that didn't fully discharged will build back up in that tube and then you'll still have another little bit of charge left in here it's not even as much as the original charge and none of this is enough to really you know blow you off the your rocking chair okay it's like again it's not running when you're doing all this and this is a second discharge but the tube can build this up so you can always remove this anode cap like I'm going to do on this TV in a second and then you can let it sit and then come back and discharge the tube again or you can sit there just keep discharging the tube for a couple minutes you can sit there and tap tap tap tap tap as many times as you want come back tap it again tap that tap that baby all right let's see him let's see him do it the same process of just slipping this under there and discharging that to make sure there's no current running in it I don't hear anything so it's good to go okay so now that I've safely discharged this CRT I'm going to go ahead and remove my CRT ground cable and then we're going to go and use some brushes and get a lot of this dust off here I've seen other videos where people have used uh cleaners and sprayed it uh I'm not going to let I don't have enough time to let this sit and it's really cold in my area so I'm afraid that any water May uh freeze or something if I let it get in any kind kind of Electric electrical component so we're just going to use compressed air and uh brushes to get a lot of this dirt out I know also people get concerned about capacitors and maybe getting shocked the only other uh area that's of concern right now would be where the larger capacitors are down here but they're on the bottom of the board and uh they but guys I know a lot of people like talk about this stuff like capacitors being super dangerous but most of the I've never had knck on wood I guess right I've never had an actual personally again I'm not this part of this discussion is just me I'm telling you the truth I've been doing it again High count of CRTs I've worked on there is maybe a couple times twice where I've actually seen a a capacitor on like a board similar to this board actually zap uh when it's turned off and you're just working on something and it shorts out together which would cause a zap but again I want you to think about it it's not a zap that's going through your body this is going to be a zap on a small capacitor point and if we look at that let me get a used capacitor it's going to go it's going to go short short distance between your finger so most of the time what's going to happen is it's going to burn your finger okay could burn it could burn it up like zap it but it's not going to actually it's not going to actually like it's not like a uh capacitor that's in something very dangerous such as the higher end big capacitors you most of these small capacitors are really no no problem and when you're discharging like this it's not really an issue you don't need to worry about it you could go in afterwards when you pull this board out and take a little screwdriver and discharge every capacitor but I don't think that's going to be actually that's a topic I want to talk about what about what about that what do you guys think should we leave that even in as a discussion the capacitor part this out cuz you can't uh you can't get shocked by the top of the capacitors so those aren't going to be really any Hazard there's no large capacitors at all on this board uh I don't even see maybe one capacitor on this entire board back here for the neck board on this TV so there's no real danger there just be mindful still of the anode cap area as occasionally uh energy can still be built up in your CRT tube and if you were to um take that out and there might be chance that you could get some electricity come off of there but that's very rare and you're fine if you leave the anod cap left in so um there are special brushes you can use but honestly I found that a good high quality paint brush that doesn't have paint on it of course but um one that has nice bristles that are tough that are not going to damage anything either kind of soft also does a really great job of just brushing a lot of that dust off the top and that's what I really like to use cuz it gets in between things safely and it doesn't leave anything behind so that's just a little tip uh now you can use a yeah let's talk about some things too like people a lot of people will Grill me online because again but I'm trying to tell you this this is not this today's video is a discussion about safety and uh we're going back looking at this old video kind of critiquing it and again we're talking openly about things this is in no way like meant to be your complete guide to safety this you shouldn't we're openly discussing things where I have a ton of knowledge and things and mostly learning um on the Fly and I don't want right you can't really take too many precautions when it comes to safety so again when I made this video video that's why I had a lot of I had the double uh gloves on I said a lot of the things about leaving it longer there are going to be times with other CRTs where it will zap every time people are bringing up CRTs in the arcade systems and yeah those can be violently zappy okay so that's not uh there's going to be times like that where you need to know kind of what you're working on on so we're just openly discussing this so that we can get we can get things right in a better video yeah and it any look hey absolutely anything can happen right even let's say something even on this tube it could I've seen him like zap twice but it happens uh you could come in here and the Integrity on these parts could be worn out you don't know it zap you right okay the most important thing is to be comfortable and know what you're doing and and be aware of the risks that there is risk there's always risk in this stuff this I thing and I think that again I like talking about these things kind of like this but again this is not meant like oh you have to do it this way this is the only way right there's different ways to do things I'm just giving you through some knowledge firsthand of what I experience what I do and and again this is not plugged in this particular one hasn't been turned on in probably 5 years it's been parted out it's been opened up it's just a demo model the darn ano cap is completely epoxied in completely epoxied in and again this has a discharge bleeder all these this is one of the more really really low-end pvms it has like a third of the parts are just missing so the discussion is here I think the important information is to try and make sure you're just most comfortable with whatever you're working on and again e either way I think it's an open ended interesting discussion okay and the last thing look the last thing I want to happen to anyone I don't care the situation I would hate to have anybody hurt themselves working on a CRT and saying I did something that would cause that now I realize this is the internet and this is just a show and like the live show and if uh what whatever you do is up to you you you take watch these videos and and this is uh and then you move on from there you can either use it as an entertainment you can use it however you see fit but again it's not there's no rules there's no rule book here it's like I'm or there's not officially any rule book uh this is 8040 it just has s video composite only one input line no like half the stuff on this board is just missing okay well let's go back I think Steve's finally going to get in here and discharge this tube this has been sorry about that this has been something electrical brush so you don't short anything out when you get around uh the boards and things but most of the time this will do fine on a CRT oh man so take a quick look back here at this board with me this is why you have to get in here and just inspect your CRT after you get it and make sure you clean it just look at this enormous amount of dust built up on these capacitors and these are the important capacitors that will affect your geometry and everything you know if um and all this excess buildup will just act as a uh as a heat uh insulator sorry a heat insulator and it will wear these parts out cuz heat will build up quicker in them and they're already um over 20 years old so it's a really great idea to get in here and get as much of this stuff off as possible um even the fly back over here let's let's pan around and look at that too yeah okay just disgusting all kinds of dirt and dust so what I might I don't know I'm going to try to do some more cleaning on this thing but um if you notice this flyback is just filthy so let's get it cleaned up and uh see how this soot around these adjustments this does have Focus adjustment and a brightness adjustment on the bottom and um so that's important to note oh and even inside the shell is just absolutely filthy if you're looking up here around the front so this thing has um years and years of soot and nastiness built up on the inside it ra it could use a full disassembly and extreme cleaning so may maybe we'll do that in a future video but for now let's just get it cleaned up enough to continue talking about safety on it okay so one more thing to look at here is this cable that's going from the flyback and it's part of the ano cap and just look at how much dust is on that just be simple easy wipe down and actually it's just so black it's not coming off so this one's got some extra so in it it's not so that's not actually that bad it looked really nasty but it's not actually on there the dust is it's pretty well off that cable so let's go ahead and start looking at some of these areas on here again this anode cap is a a very dangerous spot on the CRT just be mindful of that okay and anything attached to that so you've got your anode cup you've got your cable and then you've got that going down to the fly back so let's just start with this cable it's good to inspect this cable make make sure there's nothing wrong with it no splits nothing while it's discharged make sure the connection's still good down here at the fly back and everything uh because this cable you know it's doing it's going to be sending all the electricity into the back of the tube uh the second area to watch out for on the back of all this is on the Yoke assembly which is this area right here uh it's this white ring all the way up to this okay so we're talking about the Yoke assembly again that's this area between this white portion and this little screw right here and this is what you can adjust uh you can undo this screw a little bit and then you can adjust this left or right if you have a yoke problem where you may have a screen that's tilted or something that's what the problem is is this yolk is tilted somehow and you can just loosen that up and tilt it uh unfortunately a lot of times you have to do that while the CRT is running so I do need to be mindful of these points right here this and this I'm actually glad I remembered to point this out I thought I didn't uh these points right here now when you get inside and like this is this is pretty much after servicing put cleaning it putting it back together right you're going to start to or you want to make an adjustment so you have to use the with the voltage on this is not something you should you know this is high level stuff because you can zap yourself on this this yoke you see these points I'm I'm pointing at there's no there's a couple of them that have heat s or heat shrink tubing on them maybe just that one there's voltage that comes through there so if you were to put your hand and touch those points you could ground out and definitely get get yourself a zap off that Yol from this box and there's like usually one on top one on bottom so I'm glad I remembered to point that out point and these three points right here on the back of this plastic on CRTs like this standard televisions these are usually exposed and can be shock points so do not tap into these points right here be just mindful of that uh cuz there is current going there and if you ground it out there you could shock something so don't do that let's go down here and look at this area these are our convergence Rings which on a standard television most of the time to adjust convergence you have to move these rings around hopefully that's not a problem on your TV because that's one of the hardest things to adjust I won't be doing that in this video and I don't recommend that unless you're highly skilled and have a lot of equipment so you can get it right okay so when you're working back here sometimes you might have to come back to this flyback and this is where the electricity is generated going to the tube and it's it's coming from this uh flyback right here so occasionally now this one's still dirty but occasionally you have to come in here and and spin these potentiometers and um you see they're they're threaded so you can use a screwdriver in there so if you use a screwdriver with a plastic handle you'll be fine you can turn those clockwise and counterclockwise and it'll actually increase your screen brightness with this bottom one and this top one will increase your focus so if it's a blurry screen this is how you fix that all right Brandon the voltage is not nearly as high through that uh that winding on that yolk as it is through the like the anode cap nothing's going to be really as high as that there are points that you have to be careful of on a CRT especially if it's running any board you don't want to effectively touch together two points to bridge them two boards you don't want to touch together to zap yourself but a lot of that stuff is isolated in the way it's designed on these newer age CRTs which would be like after 1985 usually uh of the composite and Beyond video era um they're going to be isolated where the high voltage is like if you just look at this one for example and again this is going to vary between CRTs and we're just discussing this one is the example model you your high voltage is coming in through here so the tubes a spot that the only exposed points you have in the tube are here and then you have the back here where the neck board is so obviously anything on the neck board is also a point where you could get extremely high voltage sit into you and and hurt yourself the neck board when it's turned on is high voltage City okay it's really can be dangerous to touch anything on a neck board that's where it's going it's the the the voltage is being sent in through there and high voltage through there and that's that's energizing the gun those are the two points the anode and the cathode okay now there's other points that are going to have high voltage through them there's going to be down here where the transistor Transformer is the flyback Transformer and also the power supply here we're using a switching power supply that's over isolated on its own isolation but it does have points where it's running where voltage comes in you get plug in your voltage back here there's going to be points where it's running over to this power supply so there's always going to be chances of you you know zap something like that but um that's a good question there's not it's not the same amount of voltage going through it's not like thousands 31,000 I think it's like 31,000 volts goes into the tube at the highest points usually and that's not how much voltage is going through the the Yoke that would be insane but good question let's continue finish up here with what Steve has to say hopefully okay so at the other end of the CRT we got most of our stuff that's pretty harmless now again I said this thing's broken so um we may be able to just remove this whole piece and insert a scar input right here and then we could wire up RGB but this right here is the RF tuner and then back here we've got our chips that I'm sure is our um you know some kind of processor for menus and everything and then running the and then we've also got the jungle chip so we should be able to insert a RGB signal into that and that will come up up in a uh future video we'll also replace a lot of these bigger bad capacitors and then we'll talk about how to be safer on those um some other things to note on here these areas with shielding uh can get very hot so be mindful of that and there's no reason to come down here and touch down here where they could have a lot of electricity going through but just be careful of that if you ever have to come back here and work on it while it's running all right so if you're brand new to CRTs again just be mindful of the things that are dangerous inside one before before you go poking around in it really and if you have been working on it a while then this just refreshed some of the areas on the CRT that um are hazardous uh just remember that the best reason to get in here would be basically to clean it off at least first initially if you just pick up a CRT and you don't even plan to mod it it's always great to clean it off and that way um you could prevent any kind of problems from maybe happening um the next thing would be if you needed to make an adjust on your screen brightness or your focus or your convergence uh everything else would be done through the service menus so a lot of times you don't even need to open this up if you just need to fix something all right so that looks like that's pretty much the end of that video and I I still get kind of surprised sometimes how many views that has that's a ton of views on that video so let me uh me get us back here to a normal spot how that let turn that back up [Music] and we'll get back here our face View and uh open it up I'll open it up guys if you want to send me any suggestions or questions here live you're welcome to do so but also if you're watching this on a playback and it's not live feel free to drop a comment in the comment section so that if there's something that you think needs to be covered better in the in an actual safety episode again this is just a open discussion that's like a bunch of people hanging out have a good old discussion about CRTs this is not meant to be your safety guide this video this is a discussion about safety open-ended so do not go through here and start saying oh looks crazy Steve told everybody to not use safety equipment to go in and use their bare hands and lick the anod cap and you know smell it and make sure it was nice and hot before you you you stuck your hand in there and Zapped yourself good [Laughter] okay oh yeah thank no thank you everybody I really do thank you gra it's again it's an old video it's fun to I I'm giving myself a hard time because I like to and and it's it's safe to make fun of yourself quick question I got a CRT from an older person that it's kind of what it smells to be old person like if you're just have to go through it like I just showed you and try to clean your set you can watch that video again uh Amino if you find a CRT and you don't know anything about it is it okay to bring it in the home and push the power button sure why not I mean try it out but do it outside try to you know do it outside in the garage if you're real concern you don't think it's safe open it up and just look don't start poking open the Shelf looking in there and say oh looks it looks like everything's plugged in that's important yeah C shock will not Grant you any superpowers okay not going to [Music] happen Snuffer stuffer so what happens sometimes with the Yol the yolks can get stiff and most of that comes from maybe we'll maybe we'll be able to come in here and show you a little bit closer oh Cole is really snoring big time it's going to be more difficult but what happens to show you here kind of but let me get you let's see get a poker pointer so if we get down in here this area and that's probably difficult to see let's see if I can get closer oh that's better so you get down in this area what happens is you loosen up this yolk you loosen up your yolk ring over here right and it's still stiff really that's two things going on you've either got some kind of like the epoxy could be up here in spots and it's actually securing the yolk to the tube and to the wedge it's all secured together that happens a lot okay and then if you go down here uh go down in here and what happens too is this you see this piece of there's a piece of tape on this tube yeah the the dog is snoring like crazy right now anybody can hear it anyway there's a piece of tape around the tube what happens is is this piece of plastic just m melts to that tape a little bit and it forms a bond so you generally have to do is loosen that up and then you start turning it slowly left or right working it back and forth and it'll eventually Pop Free from its point where it's stuck together and then you'll be able to move it it'll be super loose okay so people are asking about let's see what was that I think your question is about if the power ca's missing if I generally see one with the power cable missing it usually means that some Scrappers come and cut the power cable off just a steal the copper out of the cable and left the rest of the set behind so that doesn't generally mean that it's bad a lot of [Music] times well uh demo um I'm not sure which points you're talking about sorry just manhandle it a little bit yeah that's the that's the that's the real way to fix that manhandle it give it a little bit squeeze turn it left and right it does this get stuck that's quite a common thing where it's just not been moved in so long and that is a point right in here you got a lot of voltage again going through this part and it gets really hot right here right in here so that kind of melts over time over 25 years
