All this talk about VHS's is frigging awesome!!!!!!! I truly miss them days!
I have a couple of VHS players/recorders..........Can't remember what brands or how old, and a ton of old VHS tapes in a very large box. Hell, some of them are recorded tapes from having it hooked to a TV. I remember Syfy had a marathon with The Stand and I recorded it. Been some time now.
Older units or modern ones? Either way you should take them all out from storage & make sure they work. If not, then maybe you can fix them? It's a very satisfying job
Speaking of VHS repairs, I'll be having more stuff to show & talk about soon. I'm negotiating for yet another (older) VHS unit, made by Casio. Description reads "doesn't work, won't accept the tape", so it's clearly something to do with mechanical deck. I might be able to pick it up cheaply, or even trade it for a modern (and cheap) DVD player in which case I'll only have to pay for new parts, in case I'll be needing any.
Meanwhile I got some problems of my own, that Funai-Shintom unit is having a weird problem with the tape speed. I'm guessing it's electrical fault, but until I confirm with my meter, it might as well also be mechanical one. What happens is that during the playback tape gradually slows down to the point where the picture (and sound) are distorted. It only happens after 5-10 mins of usage, so I'm guessing it has something to do with either voltages or control head. Sometimes playing in reverse, going back & then reversing again to regular playback helps with the problem (temporarily corrects it), but it usually reappears again within 20-40 seconds. Actually, now that I think about this, it sounds like a tape alignment issue, which SHOULD be fairly simple to fix... Either way, this will have to wait for a day or two, since hunting down the problem might take me a while, as I want to do it properly.
Edit
Well, I don't want to jump ahead of myself here, but it seems I fixed the problem
Took the VCR apart earlier today & after analyzing the situation inside, I assumed it's the Audio/Control head behind the problem, so I tried to adjust it. To my surprise, it actually worked, I managed to stabilize the picture but only for a short while, before the problem reappeared. This led me to a (wrong) conclusion that I'm dealing with damaged A/C head, so I replaced it... I found at least two other (identical) heads laying around, so it wasn't really a problem to source a replacement part, except of course the actual calibration process took me a while, since the head has to be perfectly aligned, in order to read (or record) the signal. Anyhow, long story short - I still had the same issue despite using a "new" head, so the next step was aligning the tape. Then the VHS threads the tape around the drum, it needs to be perfectly aligned, so that the tape goes from one end to another, passing through all the 6 "checkpoints" so to speak, before it's being wound back into the cassette. This includes the following: Erase head, left takeout arm, head drum, right takeout arm, audio/control head & pinch roller, then it goes back inside the cassette. However, it seems the alignment was just slightly off-track, causing the tape to be out of sync with the heads.
Still have to give it a proper test tomorrow, to make sure the tape isn't getting wrinkled or damaged in any way, but as far as the signal goes, it seems to be working OK now.
Edit2
Here's a nice (and educational) video on how to set the VHS tape alignment using the scope. Unfortunately I don't have one available, and even if did I wouldn't have anywhere to put it, since I don't have a proper "work bench
There's just too much stuff laying around, so I have to use the more conventional methods instead. In other words, you power the VCR & tinker with takeout arms, until you get decent sound & picture, without wrinkling or tearing the tape in either direction (upwards or downwards)
