Hi Dave, I follow you for some time, I love your videos, I watch them all even if is not for something I need to fix. I work on IT but love to fix stuff. How do I get in touch of you about fixing a audio equipment? I'm in Oregon US. Anyway, I have a Panasonic RX-DT690 where the tape deck was working but one of the "rollers" that rotates the tape came off (not the rubber roller in touch with the capstan) so I had to disassemble the deck to hold it from behind to behind to snap back in. So to do that I had to lift the cassette circuit board a little bit. Not the deck is unresponsive, when I press play or any of the buttons, the display shows the action but nothing happens, after a few seconds it displays the error H01. I wonder if I burned something on that board when I lift it, maybe it touched a metallic part and shot circuit...dont know. I was thinking on sending it to you to fix it. Thanks, Fernando.
Nice closeups of the boards!! I like how they put on the silkscreen all the circuit blocks names. That's a nice detail. I guess the problem with electrolytics is that liquid on a sealed can. The seal won't last forever. Electrolyte formulation is important. But at the end they are small batteries. And batteries leaks when discharged too. Water based ones dries, specially in hot environments like the ones on the CPU VRMs of some computer motherboards.
Was leaking capacitors just a problem from the 80's and onwards? I can't say that I've ever seen capacitor leakage on anything pre-80's, but I wasn't there.
Did you salvage the usual parts from this cam corder? Love these vids you bring out. Giving old tech another chance at life or at the very least. Doing a tear down to see the insides of the old hardware and how it worked. video request, would love to see how you go about cleaning mold off of VHS and Hi8 tapes etc. I know there are other videos about cleaning mold off tapes. But I'm interested to see if there is anything that you do that might be different as well as any advice you could give.
So it wouldn’t be economical or sane, but theoretically, assuming the capacitors didn’t corrode the board, if one replaced the caps, the camcorder would work again?
Are the caps on audio equipment from the same era also a problem? I've been looking at an old Aiwa component stereo but was wondering if it would be subject to this kind of degradation.
There were many cap problems in the mid 80s to early 90s. More the compact capacitor design. It was when they switched from oil based to water based electrolytic. If a manufacture user certain brands that had the problem they leaked. Elna had tons of leaky caps on sony and Mitsubishi VCRs.
I have this camera Sony CCD-TR317E: the playback is distorted, I recorded some stuff on it and the playback still distorted..any ideas about the cause of this?
@@johnhpalmer6098 I took it apart and I only could find one capacitor which according to my testing nothing is wrong with it. when used as camera it gives me good picture, the only problem is when recording or playing back the tape. I unplugged all flex cables, cleaned them and added Deoxit 100 to the connectors but nothing changed.
I managed to obtain a Sony GV-9 video walkman that has this board design and is dated 1989 but works perfect as it looks like the caps were replaced more than once over its life.
It's a real shame about these old units.. I would love to own some of these larger older 90's units for my camera collection but they all seem to have bad caps now so most my range is 1997/1998 and onwards. I can't believe a company would have only one person with the info on how the caps are made.. I seem to recall it was down to all the companies trying to buy the parts cheaper and they did from some company in china and they all went bad and they swap to a new company for the parts but I guess will never know the truth behind it all haha.
The rumours were one of the workers stole the formula when he left but the formula he took was incomplete. Perhaps a "bait". Whatever happened the company making caps that Sony and canon used were all bad and they failed after a few years.
This is great never a dull moment while watching your videos Dave. Very complicated camera designs. At least you have a large screw selection now!

I heard that same rumor back when I was repairing electronics here in the States.

80s and into mid 90a

Do you have tutorial for simple am/fm radio fix.
Do you think if they made those units with the caps they have today, they would last much longer?

If the board wasn't shot yes.

Leaking capacitors on anything will cause that. Doesn't matter the era.

maybe they self destructed due to the amount of homemade sex tapes these things were used for lol

As already said, likely your caps have failed if it's of this era.

Did you used to repair cameras of this type or similar? You seem to really, really know where everything is! Very cool.
Yes unfortunately I spent over 20 years slaving away on these bloody things. I hated every minute of it.
A lot of computers died because of the same capacitor problem.
Sounds like the same rumour resurfaced for the mid- '00s cap plague where they'd all build pressure and the tops would blow out...
I heard the 00 issue was fake branded caps making it into the supply chain

Or it was used regularly.

Good good
I hate this models very very problematic
