56:34 Well stated Dave, I have a customer who brought in for repair a Sony GV-200 purchased from an ebay seller who "specializes" in Sony. He had fully restore it and it worked fine for about 3 years and then suddenly the color now slowly fades like a line down the display to BW. If I slightly bend the mainboard in one corner the color comes back. :)

I got a slvr1000 shipped in that was rebuilt from a big eBay seller restorer. It's on my channel. It had a broken board that soneone attempted to fix, poorly.

You've stolen my thunder! I'm just editing together a video for release this week where I repair a Sony EVS1000 (same "Sony U-mechanism") and exactly the same linkage had fallen out. And a heap of other problems too, of course. What's the chances of that?! Well perhaps this was a common problem. I took the deck out for slightly better access. I probably made work for myself too because I removed the cam gear that the linkage had fallen off, so that had to be re-timed when installing.

You mean M mech. The U loader has a gear that spins like the one in the opening logo. I have all of them.

@@12voltvids Strangely enough, "U mechanism" is what Sony called this one, despite the fact it uses the M-loading system. Just checked the EV-S1000 and 3000 manuals to confirm.

I had to change 22 bad SMD caps on a PCB with very fragile traces. I don't have SMD tools, and when I used a sidecutters it would break the trace. Ended up using a soldering iron in each hand, hitting both legs at the same time. Felt weird but worked incredibly well.

@12voltvids 9 ай бұрын

I've done that. 2 irons. Only problematic when the caps are very close together.

Unrelated to email, but I found out KZbin was storing videos on my phone. Found out it was for offline viewing. Maybe I did download the videos, but couldn't find them. I had to turn off downloading videos in options. There are so many ways space is wasted. Interesting story about your email spammer. And great VCR repair, which I will watch now.

Thanks for reminding me I have an EVC3 in the cupboard that I think just needs new caps in the amplifier board under that silver metal box. It plays BW then after about 5 min changes to color.

Hi Dave, Another interesting posting, thank you. It’s amazing how much damage can occur from leaking caps - sometimes quite a distance from the guilty party. I blame “Mr Wick” myself. It’s also amazing how a preamp fault can masquerade as a single faulty video head sometimes. As for the guides, I’ve been wondering for time as to they work loose. Did Sony use some kind of locking nut or grub screw arrangement, perhaps it’s some kind of tapered thread (unlikely?) or did they rely purely on a dab of glue or paint? The things is, if it’s really loose, having set it up correctly whilst laced up (naturally), will the unlace sequence move it again. I mean, when is the glue applied, whilst playing perhaps (and certainly before an unlace)? I get the feeling that these 8mm decks get regular guide trouble. My late father’s camcorder went into Sony multiple times with the same problem. Such a shame. You certainly have some patience Dave. Hats off to you sir!!

There is a lock screw on the side. I didn't show tightening on this one but i did snug down before i even touched the guide alignment as it was really lose. It's a tiny Philips screw on the base facing sideways. I showed it on the last evc3 I did a few weeks back i believe.

@@12voltvids Thank you Dave, all understood now. Wow I bet that's a bit of a faff! I mean, you've got to have it loose enough to allow adjustment whilst laced up and running, but tight enough to stop it spinning out of position once you've finished alignment and gone and done an unlace sequence. I'm still amazed how those rogue caps got to eat the ribbon cable to/from the drum! Just goes to show. PS I don't think people can understand why firm quotes can't sensibly be provided upfront for repairs, but this posting shows exactly why that's the case. You also have to have a stock of interchangeable parts of course (again this posting shows why). Again, this is something else that folk generally don't understand. Keep up the good work Dave! I'm always looking for your next postings to keep me sane. Cheers!

That's just it and has been since the start of time. People want a free estimate. Well a free estimate is a guess. It is completely impossible to do an estimate without actually repairing the unit and do that we need to get paid for the time. So what happens here is I have spent the time and hopefully things will work out. The owner could just abandon it which has happened before. Since i don't need another 8mm player I would end up selling it but around here these do not go for much. I know people will say they go for hundreds on eBay well i have tried eBay before and none of mine have ever gone for much. I had a tascam da30 dat up on eBay for 4 months. It finally sold for 52.00 and when the buyer found out the shipping was 120.00 to the states they wouldn't pay so I got stuck with the closing fees. So i listed again and this time i put 140 shipping fee in the ad and got no bids. So here it still sits.

Hello, i’m from the previous video and I just wanted to let you know it was the Sony Handycam Trv308. My issue was that the camera would always be black when recording and when I would playback the video it would have the same black screen but have audio. I believe its the camera because the user interface still works.

I had the same problem with the exact same deck, on my Sony CCD-V6000 Pro camera when I changed all the SMD capacitors I had to re-grease the moving parts, put super glue in the holes to keep the loading brackets from coming off and remove a yellow sponge on the head near and tighten the alignment screws the camera will write and play the video correctly just sometimes there are some colorful horizontal bars this will also happen when I don't play a tape directly the CCD image on the TV when I turn off the digital effect these bars will disappear maybe the two throoghole capacitors that I didn't replace on the TBC digital board, such a good technology that went bad unfortunately, do you know any hi8 player that supports TBC?

@@12voltvids In my case, what do you think, I have cleaned the boards and changed all the capacitors of the camera, the camera works normally sometimes and some other times colored horizontal lines appear both in the reproduction and in the direct connection to the TV from the CCD. and when i turn off the digital effects the horizontal lines disappear

@12voltvids 9 ай бұрын

Sounds like a grounding issue somewhere in digital board. Remember these are multi layer boards. Any crap that leaked our if the caps has already wicked into the board and eaten into internal copper traces which can cause an intermittent or permanent failure. The v5000 and 6000 were full of leaky caps. I had one way back and i totally recapped it back in the late 90s avd sold it. A couple years later it showed up at the shop with intermittent faults related to the bad caps that had already been changed. It was condemned and scrapped at that point.

@salvatorev_ 9 ай бұрын

@@12voltvids the digital board has been completely cleaned there is no leakage oxidation anywhere, maybe it must be the bad grounding because I didn't glue the grounding of the board to its metal case enough I will probably have to look at this at some point, however the camera sometimes shows these colored lines and some he plays very correctly 🤔

@12voltvids 9 ай бұрын

You can't clean the board. You can only clean the surface and wetting the board to clean creates more trouble. The boards ate 4 or 6 layer. There are traces sandwiched in between and any liquid on the surface of the board soaks in and spreads out into those internal layers and causes damage. Yes you need to resolder the metal can to the board, but if the damage is internal it's impossible to fix.

updates and processors all they are doing is updating to make the processor run slower so you eventually have to update your phone. I have so many expensive equipment that runs like shit on i7 processors and runs perfect on a ancient core 2 duo processor with more power and performance.
