I have a same vintage SVHS Panasonic with the exact same playback / FF issue. I put it aside to look at eventually ... Looks like you found the exact issue, our old friend broken solder joints. Thanks!

Isn’t that around the time when they started having lead free solder in products? That sure doesn’t help.😂

Yup

Always a pleasure watching your videos, your a legend in electronics! I’m trying to learn as much as I can off your content. I have a question I hope you can answer. I’m loading a tape in a dvd/vcr and it seems like it begins to rotate counterclockwise for a couple seconds before it stops operating. I don’t see a mode switch and I’m also wondering if some units?

@kyoudaiken Ай бұрын

Pausing at 5:25 I think this thing is out of alignment. And maybe the mode switch has some issues as well. Let's see if I'm right. Edit: Ah, the sensors! Yeah, these stand up tall and over time these solder joints can crack. By the way, it also happened when they used leaded solder. Yep, something is out of alignment over all these years. Flimsy chassis as well. I wonder if you could put something that pushes the mech to the right. Like some scrap plastic or so and epoxy it to the case, pushing it over to the right. Or maybe manufacture something that makes the front face push it to the right.

It only dies it with this tape so perhaps the tape is a little our if spec too.

@@12voltvidsjust yesterday I was having an issue with a cheap floppy disk that was molded slightly out of spec and would not load and seat fully on the two alignment pins. Cheap ass Chinese crap causes so many problems all to save a penny or two.

Just raising Tariffs alone does not fix the issue. In order for that to work some tax money should be... (Diverted) and used as incentive for companies to begin manufacturing again in Canada. Otherwise I agree with you that raising tariffs just causes things to be more expensive and China is fully capable of absorbing the loss. Also tax breaks on companies that manufacture locally would also help. Is that going to be a painful change? At first yes. Anyway, just an opinion mind you, however I can say that we tried it here in the US and it was starting to work. there is a TV manufacturer called Element that was staring to make TV's in the US for a while. Two problems. 1. we did not have the willingness to follow through and help element continue so they soon stopped. also, Liberal politicians soon stopped caring about tariffs stating "China is our friend, why would we want to hurt their business?" Not an exact quote but yea, you get were this is going. When I hear d that I knew this was not going to work. at the end of the day, you just end up paying more for the same crap.

No kidding. Trump did that with aluminum and steel made in canada to try to get the us aluminum and steel production back. All it did was drive up prices. A 30% tax on aluminum used to make beer cans for example just put up the price of beer. Even for us because many of those cans were shipped back. They won't spend the money because they are promising tax cuts. That's how they seay voters. They promise that they are going to save us money they cut to the bone, everything goes up in price, services go down. Then they get kicked our and the other guys get in spend a bunch of money fixing stuff and they get the boot because taxes go up. I hate politics. The guy in now is an idiot but the opposition is down right scary.

I would have guessed mode switch. Edit: Used to tape over the little button to hold it in when I had a tape that wouldn't open the flap while loading. That was a very rare occurrence. I even put the reels in a different shell sometimes.

@12voltvids Ай бұрын

Mode switch is the go to, but careful observation showed fault only happened on forward direction not reverse so that took me right to the rotation sensor.

@ArchivoHumano Ай бұрын

Why is it common for the solder joints in those sensors to crack? Do they experience any stress?

@12voltvids Ай бұрын

It is common. Especially the end sensors.

@@12voltvids The ones with plastic gears will be. I have some Sharp ones that used idler wheels and belts and i still have plenty of service kits that i bought when they were been sold off, The best i have found for still working are the Sony decks that you can still buy the blue gears for. replace the capacitors at the same time and they will keep going until the head tips wear down. Why buyers raved over Panasonic decks i could never understand. Mitsubishi made some good ones, but sadly they have long gone.

Same here. I got out June of 2003 and didn't pick up a screw driver again for 10 years. it was this video: kzbin.info/www/bejne/kGS7eneto7ONnqs That brought me back. Let me explain. I had no interest in fixing anything. I had moved on, working for the phone company was happy to not have to deal with electronics. An old ham radio buddy had this satellite receiver he was having problems with. He wanted me to help him fix it. I was at his house replacing an LNB on his big dish for him and he hauled this one out and asked if I knew what was wrong. I said looks like power supply and he wanted me to fix it right there. I told him I didn't have the tools but would take it home and fix it. The old guy was disappointed as he wanted to see the inside, so I offered to shoot a video and put it up on youtube so he could see it. I already had the channel, and the name was due to the early videos I had done on the 2012 chevy volt. That's where the name came from, car videos. I put the video up but forgot to make it unlisted and it started getting many views. Hit 100K views within a month and youtube reached out and asked if I wanted to monetize as they had been monetizing the video since it hit 10K views in the first few days. My first payout was about 300 for 1 video, and I got the idea that i would break out the camera and film me fixing a few of my broken devices. The rest is history. The shop I used to work for also closed their doors permanently about the same time so former customers were looking me up asking if I would work on their stuff. So I came back as a side gig, mainly for the content creating opportunity. I make much more from the video than actually fixing this crap.

Tape frame is shrinking! : (

@12voltvids Ай бұрын

Could be. Only that one tape was problematic so perhaps the cassette shell is a little off. I tried about 8 tapes off camera and only that one tape hangs up so it us probably a little of both.

The older VCR are of much better quality except JVC =junk video Corporation . Sony made some good vcrs but when they got too like 2000 it was all downhill from then on

@12voltvids Ай бұрын

The best era for VCR were late 90's. Sony always had the best video recorders when they made them in house. Sure some of the sony units had issues. The blue gear, which is still available, and some power supply issues because they used off the shelf power supply units and they had bad caps. Sony had the best SVHS on the market. The SLVR5 was fantastic and the SLVR1000 even better. Even though they did not have a TBC they had a video circuit designed by Faradja labs which featured very good stability and chroma processing. The quality off these machines (and the industrial SVO2000) is at the pinnacle of VHS and SVHS capability. Of course this is to be expected from the company that invented the video cassette recorder. JVC can claim they invented VHS all they want, the fact is without Sony inventing the VCR format itself (Umatic and Betamax) and having a strong hand in the VHS system too it would never have existed. Now someone is going to try to prove me wrong, but I was working in the industry at the time Sony released their first VHS recorders, the SLV555 and SLV757. On all the sales literature printed right there in bold print stated that Sony co-developer of VHS format and inventor of the video cassette recorder. The fact was they shared information with JVC believing they were on board with a universal standard that all the japanese were working on, Betamax, and JVC released VHS and gave away the patents to anyone that wanted to make them.
