Sanyo VHR H600 VHS VCR No Tape Load

today I have a sanyo VHS hi-5 VCR mechanisms jammed won't load a tape so obviously it's not gonna play because you can't put a tape in it anyway let's see why this one's not working if we can get this one going I'm cleaning out my garage so I get to get this stuff working so that I can sell or give it away so let's check this one out and see if we have six s annual VCR and watch it that's what the symptom you have to listen I do this too here the motors you hear the drum spinning up and I can see the front loader trying to move but the front loader is is back aways so let's take the top off this one so I try to try on the power you see it's trying to load so I believe we have a timing problem on this one or maybe a mode switch problem so we're gonna remove the chassis there's a couple more screws to take down the front here there's a couple more screws on the front to add there's some furs on the bottom so you just remove some screws here my cats hollering you can hear them once the screws are removed now plug the drum and they behead from the preamp and now I should be able to remove the chassis so here's our mode switch on this one we will clean this for sure and check the timing of the mechanism so the mode switch in eject mode sits like that I should be able to pop this one apart without I'm soldering it too I just get a screwdriver in here I should be able to pop it apart oh yeah that's it needs to be cleaned you can see see the oxidation that's probably what went wrong with this in the first place is the remote switch got dirty and caused the mechanism to blow out of alignment it's going to get some contact here put a drop of to have dioxide I'm just using the the 100 D 100 clear just because this is very pure I don't need much and I think for control as to how much I dispensed so it makes it go long long way I can also use the metal tip to kind of scratch the surface slightly to help break any surface tension and get the cleaner on to the contacts then you just cotton swab to polish the contacts up you can see what came off of these contact that's a little cleaner than we started do the same for the switch contacts himself put a little bit of deoxys on to the contacts and wipe them and then we put another drop or two onto the switch so we can work it in with the the switched rotor pop the switch back together and give it a couple spins and be sure we align it with the eject mode with the little mark timing mark that way when I put the mechanism back together in the eject mode the timing should be correct for the mode switch also on these chassis we don't have a problem with it now but other things to keep in mind that can cause problems on here is these rotation sensors they read they stick up through the bottom and into the real tables and they read slots in the real tables that go through here and here and basically they're just an infrared beam that shines across and as the real table turns it's got slots in it so that determines how fast each of the wheels are turning that's used by some features such as calculating how much time remains on a tape because it calculates the relationship between the supply and the take-up so these can fail and if these fail your symptom will be the intercoastal to play for five seconds and stops or three seconds or whatever it is let's take a look at the actual mechanism itself looks like our timing is off by a little bit looks like this gear here is out of position for starters the other ones I don't know look they might be okay that's just let's just remove this mid weight gear that way I can work everything else through its paces and we'll remove this gear this is the gear that operates the front loader now with the front loader is ejected this gear here as it turns this is what operates the mechanism as you can see it operates the the main cam which loads and unloads the tape as it goes to the modes main plastic cam lips to be okay on here they don't see anything broken everything seems to be going through its paces this cam I think this cup washer holds it on so that won't come off but typically on this one you've got one main timing mark assist in you can see the word in there that's going to probably face towards a timing mark on this Midway gear and when it's loaded there's different modes that it goes through FL it's probably fully loaded there are also timing marks I've never worked on with these make that so first light so I'm kind of learning as I go along but if we look down through here there is a timing mark there is a hole in the chassis you can see it right there so those line up and there's another hole down here these line up when the mechanism in its it's unloaded position there's a hole on this gear here below can we see it when I kick it all the way out or not yeah there it is there you see that hole there so that hole lines up with this hole here when it's on the unloaded position so those holes line up that hole lines up and this the laird in over here is going to point towards this other gear there's another timing mark over here and that's pointing towards looks like there's a timing mark on this gear to let me just get a closer look at that see the timing mark there so that one's the timing is correct right those two are lining up with each other you can see right there it's a little arrow there those two arrows point together this one's gonna point at the front loading gear says FL so that's gonna point towards the front loading gear and this one's gonna point towards the other gear so when you have these these timing marks lined up this mechanism should be ready to go there should be a timing mark on this one which there is there's a little indentation there so when this when this front loader is all the weight forward I should be able to drop this gear in place and line up those marks and snap that in place now when I turn this gear by hand I should be able to load the mechanism and have the basket operate and drop into place and go through its motion so let's do that before I put this gear back on so I have to release the latch there's a there's a latch on here to stop the cassette from being pushed in unless there's a tape in there's a little lever here that we have to pull down and that releases this catch right there so we pull down that catch start the mechanism moving as I turn the gear I can cause the mechanism to drop like that as I continue to turn the gear here we have our one of our tape guides pulls into position and I mechanism loads and there pinch roller no engages as you can see so this should work I don't know what's up or there's someone jammed the tape or whether that right I suspect what happened is the mode encoder switch was dirty and it caused the motor to run and it's caused the teeth to skip although I don't see any broken or mashed teeth but usually that's the case but it looks like that's what's happened is this this just gear jumped either either it skipped here or skipped here one of the two but looks like it jumped out of its out of its it's a home position so if I put this gear on just see what lines up here I don't think it matters but there should be a couple tiny marks on here in being lines up with that hole there and then this whole points over here you see so this in mark is going to line up with that hole and then this one lines up on this side and if you look down through there that hole looks like it's lining up with one below it so that I think will do it so let's just put this chassis back together we're gonna drop the chassis back in the main cambiar here is gonna drive I think the main cannon gear drives the mode switch so that's why it's got this it's got this little tooth here that sticks out that's gonna sit into this slot here on the mode switch so we drop the chassis back in now I'll just put a couple screws in it to hold it in place for now I never got a chance to work on these machines these were I was gone up and all year this is this looks pretty modern by made it and it made and then Onision what year was this thing I think this is this has gotta be after it's gotta be after 2003 I never saw any of these I don't see a date of manufacture on this thing but I'm guessing it's gotta be it's after 2003 has to be around there I never saw any these when I was in the business plug the head back in if we can get plug without breaking it that is sometimes you gotta do it that way and the other ribbon cable okay it's supply power and see whether this thing does anything different and that's a good sign let's gonna put my TV on the correct input fingers crossed that works it works volume well alignment sounds beep nope can you check the alignment on the sink sounds like the high fight audio is not tracking up right we'll just put the scope on it and check the alignment switch point in envelope is right down here in the back it's marked C envelope and this one says switch point swp so switch point in envelope right there and lifting on the scope where you are a little bit off so we're going to adjust the p2 guide here and the p3 guide to get the alignment correct so let's do it yeah that's looking pretty good no almost perfect it's not quite we're getting there let's clean the heads so we just use some isopropanol on a piece of paper hold it up against the head drum press moderately and spin the head drum to clean the heads himself and we'll use a q-tip clean the rest of the transport we're getting low on on this isopropyl but rest assured I have more have a full bottle of it run away clients got me some it's funny you know you go into the drugstores look for isopropanol and these days with the pandemic and everything everybody's buying all the alcohol they can and the kicker to this is that I'm cleaning the upper portion I'm not cleaning the heads with this the kicker to it is this stuff is 99% same with this new bottle that I've got here 99% this is good as a solvent for cleaning in fact this is what you want to use you don't want to use 70% or 60% you need to use 99% when you're using it for cleaning tape heads and the reason why is that 70 percent has 30 percent water 99% is 99 percent alcohol it's isopropanol alcohol is typically a mixture of methyl alcohol and ethanol and they do that so that it's denatured so that you're not going to drink it because ethanol is what's in booze but methanol is toxic so they mix the two alcohols together but it's still 99% alcohol to make their rubbing alcohol of 99 percent which is isopropanol but you don't want to use the 70 percent stuff because 70 percent has got water and water well first of all we'll take a lot longer to dry when you're putting it on the heads it's gonna take longer to dry but also water can cause rust so you want to use pure high purity 99% alcohol for cleaning circuit boards cleaning heads and that type of stuff but this stuff's no good for people making hand sanitizer because I just I've done some research and some reading and it turns out that to make hand sanitizer water is necessary because the 99% stuff won't kill viruses and bacteria it won't break the bond it will only it will only kill what it touches on the surface and it won't it won't break the bond and get to other viruses that are hiding below that layer whereas 60 to 70 I think a sixty to seventy-five percent will the water will carry the alcohol in so people run out and buy this stuff for making hand sanitizer they're buying the wrong stuff they should be using 70% our sixty percent for that purpose or mixing this with 30 percent deionized water just something I learned after reading with all this pandemic crap going on everywhere you've turned now there's all this info out there okay there's our playback it's looking and sounding good you hear the sound no more no more snapping and crack that in poppin and if we look over at mr. scope our way firms looking pretty good and that's all I'm gonna do on this thing because this thing's not worth spending any more time on it is now working all I need to do now is put it back together and find it all home this is mine so this one I'm gonna put this up put this one up for sale seems to be that there's a market now for VCRs so now that everybody's gotten rid of them they're finding that people are finding girl tapes and they want to play them again so I've actually unloaded a couple of VCRs in the last few weeks so now that this one is fixed I'm gonna put this one up and find it a new home now the fun of putting these things back together stupid place yet hold the Mecca doesn't love the way it the screwdriver in there see I didn't have to do this taking it apart because the mechanism was already out of out of position but to put it back together it's a little more of a challenge is you have to get in there with the screws screw them in with it yeah make it as I'm pushing back on you now I'm not showing the recording of this thing because I can't do recordings up because you see this piece of crap you need a remote to clear the the initial screen when you plug it in it's asking for what RF channel you want the modulator on channel 3 or channel 4 and you can't advance past that screen without the remote it's another one of these stupid ridiculous asinine designs I'll show you power this thing up Auto setup RF channel selection 3 4 select ok to start menu TV none of the buttons on the front do anything they'll take that off and say no cassette if you press the play or fast-forward or rewind or record it'll go back to that screen no cassette if I play a tape what happens if I play a tape what will it will it or will it not go to the tuner stop goes right back to that there's no way to select the channel until you select your RF channel even though we're using a V you have to select the RF channel so a machine like this will only be functional as a playback machine it will never be functional as a recorder without the original remote that is a stupid design anyway this piece of garbage is back together thanks for watching we'll catch you in the next one real soon my
