Louis pays a debt to Sunny: 820-3437 dead because of missing S5 rails

koogler any oh yeah two gigs already it's recording raw video because I can't figure out how to make this program compress properly so here we have an e to zero 3437 motherboard from sunny here and we have to see what's wrong with it so well what have you measured so far sunny so what have you noticed so what what creates the s3's what signal from the PCH creates the s thérèse okay which which has three did you measure that was missing p p3 p4 - that's not an s3 p p3 v3 something you're thinking maybe of p p3 v 3s 3p p3 v 3 s 3 maybe that was what you were thinking about then let's try and find that that's open board view that actually works get this I can see what's there okay now P P 3 V 3 s 3 what creates this let's see P P 3 P 3 s 3 comes from P P 3 B 3 s 5 over here hmm alright so you said P P 3 B 3 as 5 as present yes okay so what's going to turn this on P 3 V 3 s 3 underscore enable did you check for that this company you don't have that on your schematic you should go to your schematic provider and complain about that all right so P P 3 P 3 B 3 s 3 and they enable comes from p.m. sleep best for L let's see if we have pm sleep s4l all right so we have a bunch of different places here that we can measure pm sleep s4l all right PM sleep s4l I'm paying back my debt to sunny from the iPhone screens and we have 0 so p.m. sleep best for all comes from what sunny yeah actually so what are we charge a day we can prorated for a two hours yeah so how about we just leave it even instead of me owing you 4 iPhone screens you owe me like 200 bucks yeah that's yeah steven steve' is the reason my credit score is what it is okay so p.m. sleeve s for all comes from the PCH and what tells the PCH what to do what tells the PCH what to do boy okay when you have a PC computer and you want to overclock it or do something with it whoa what what else huh the BIOS tells all what to do okay so here let's let's let's see what what does your BIOS area look like sunny doesn't look too bad [ __ ] and balls all right so let's see what are those two supposed to measure here those four so the two on the top of the ones that are really nasty nice we have our 6126 and i 6125 so let's go to our 6126 our six one two six and our six one two five those are supposed to both be forty three ohms let's see if we get forty three ohms Who am I kidding you're not gonna see that on the camera anyway so let's see ooo forty three arms and forty three arms imagine that Oh now look at the chip that's responsible for P P 3 B 3 s 5 look at that nasty capacitor and the bottom left and also look at that little corroded point over there let's see what that's for p5 vp 3 V 3 V reg 3 that's C 7503 that looks like [ __ ] so and also above it so this that resistor P 3 B 3 s 5 en are B's that's that's PP 3 V 3 is 5 is that actually here yes Adobe I know your PDF reader is useless as PDF reader is available and I don't care alright so let's see this PP 3 V 3 s 5 actually here this is starting to be look a little hard to believe and it's not there something you lied sorry you [ __ ] lied you lied look at the what do you mean it's there mofo hey that is five is not there what's this your multimeter measures voltage when you have the [ __ ] probes in the air okay mofo zing it's time to erase some nasty [ __ ] all right P P 3 P 3 s 5 is needed for the PC H to send out anything because that all rubber work some 3.3 volt logic and 3.3 volts is provided by P P 3 P 3 is 5 your multimeter measures voltage in the air son okay that stuff looks like [ __ ] I'm not really gonna bother looking into it what a lot of that stuff does when I can just it'll take more brainpower to figure out what that does then the brain power required you just simply take it off I need to conserve my brain give it another second heat up doner pile this thing is a monster it's a monster what I don't think it is but I don't care I don't feel like replacing that stuff and plugging it back in just to realize that a two-cent component that I didn't replace is also bet so these two can go see yeah let's see how this is nasty on the screen sunny but I'm tweezing if that exploded what do you think happens to the chip that that it's going to probably something nasty all right look at it go Weller all righty I love father didn't give me a plunger with this flux yeah since I've wanted to review it and I kind of liked it so I didn't return it there's no need to return it I think it's really cool and as this this this is the the awesome tip I don't want to ruin your shoes sunny they look really cool okay all right look at this thing this blade this blade is awesome so we're just gonna revitalize pads that look nasty see we create a little bridge over that section that's destroyed angry iPhone customers oh well 2005 it does it have colors on it I mean is it though is the iMac that has the coloring like with the TV looking [ __ ] this will scrape away the trace a little here let's get the dirt to get sucked up onto the iron and away from the board all right this thing is a monster man well er WH a 900 monster well sure foot I love this little jagged edge tip it's my new favorite tip if you want to do point and do something really fine you can just use the edge of it like this but then if you want a lot of thermal meant you know you have some with a lot of thermal mass and you just want to get rid of a bridge you can just hold it on the side so you don't have to keep changing your tips for the application that does everything all in one yeah look I mean it removed the huge bridge and it's a it's a micro pencil a little 45 watt 48 wide actually tiny little 65 there well look micro pencil is 65 and then the regular one is 80 this one is 65 for the big iron and 48 for the tiny one but it doesn't matter it still does like it works this like here moving the tiny components with the larger nozzle is harder it still doesn't I don't want any of them though those screens that you got that Tony doesn't like we Wade you buy those screens that Tony doesn't like again why doesn't he like them that sounds very e-tec of them you know I hear they took on somebody from e-tec recently maybe the quality maybe the quality came over huh oh yeah by other one [ __ ] broke I had somebody asked water use that pee that funny though coat hanger one so I did a video comparing the microphones and I said the DPA is the best and I'm always going to be using this and it literally died after the [ __ ] video there was some outsourcing that Bertha that almost caused sunny store to get broken into yeah and now this one over here doesn't look very nice that has to get covered in cider aesthetic all right we still probably have more work to go but at least let's see if PP 3v3 es5 is back that would be nice but yeah PP 3 B 3 s 5 of course we do because we have a fan spin a fan spin Steve what are you invoicing sunny for this how many iPhone 6 screens do we take and like prorate it let's see what does open broadcaster say for board repair lesson a 25 minutes of sunny yes sudden death syndrome sudden death by [ __ ] liquid that yeah it's crazy how when you spill liquid on and they just stop working why doesn't make the chip even on the board since you're gonna be paying whatever is ridiculous rate Steve has for you on the invoice let's make the chip straight this thing goes really hot look at how high that goes in here Sonny you know what me trying to move this over and make it straighter just gonna wind up killing it so that's a bad idea that thing's a [ __ ] beast alright so what was even wrong I didn't even bother looking on the schematic to see what was actually wrong with it let's see so the caps that were look nasty looking were what are they for you know how much time I could have saved if you just told me PB 3 B 3 X 5 was it there so let's see C 75 okay so this over here C 7 503 this is for the LDO inside the chip then that capacitors going between that and ground hmm that's odd why that should not be critical well I guess if the hmm let's look in context here yeah I'm really not sure why that would be critical let's see maybe it just means that chip itself has it had exploded our so in fine I almost want to go back in time and unfix it and see but yeah our seven five five to as five power enable so that resistor being burned definitely would have done something here are seven five five to via the chip would have been told to turn on the chip itself is probably bad so yeah that's that you go to Steve to pay your invoice
