Thank you for confirming, just ordered some from AliExpress, and an ESR meter. I have removed 2 of the suspect capacitors. Sorry for the dumb question but the hole where the leg is soldered to the board has small section of brown is that because I have removed too much of the solder? I was worried I may have damaged the board!

Spray alcohol and wipe with a q tip. Probably will go away
Using flux right?Comment

Not used flux as I didnβt have any.Attached FilesComment

That's a big mistake. You must use flux. You burned that pretty good. As for fixable I don't know since I've never done that. Maybe someone else can tell ya
ββββββdont do anything else until you get it.Comment

Yes, I think Iβve messed up here. Hopefully I can do can do something with it.Comment

this nothings to do just solder new one in place..
BUT good to see the circuit.. don't use any caps as yours first questioned on 680uf 10V will work,,,so don't use over rate more than 10V and don't use any over or less 680ufComment

It's not a big deal, you just overheated the pads and they peeled off, you need to add flux or use rosin, old boards used getinax (modern ones made of PCB) and they don't like overheating, clean them with a toothbrush moistened with isopropyl.Last edited by lotas; 09-26-2024, 04:55 PM.Comment

Thank you, I will use flux next time. I have some on order.
The 2 caps I removed were 680uF 6.3v and 680uF 10v. I have ordered 680uF 10v as a replacement for the 6.3v as I couldnβt see any that were shipped by AliExpress.Comment

Cleaned but it looks a right mess! Lesson learnt! Hopefully I havenβt destroyed the board!Attached FilesComment

Carefully clean (remove the mask (varnish coating)) with the sharp tip of a scalpel, wipe with an ear stick moistened with alcohol and tin the area with solder...Attached FilesComment

Appreciate your help, thank you. How about the other part of the board? (the one that looks the worst) Do I need to remove the mask?
Are the brown sections without the solder just the none conductive part of the board?, I think the pad was under the solder so nothing conductive left?
I need to understand how the board works.Attached FilesComment

Well, the same thing here, clean and tin...Attached FilesComment

I have replaced both capacitors, the machine powers up and plays videos but the dvd player audio isn't working. When I dub from VHS to DVD no audio can be heard from the VHS, the disc does record the sound though as I finalized the disc and played in another player. Any ideas?Comment

recording / copy Data are blind work.. playing / review are coding matter.. if the code not supported you can nothings do with itComment

I should of mentioned audio on the DVD doesnβt work at all, you can hear like a static noise.Comment

Hello Everyone,
My name is Haris and, I am new to the forum. I would appreciate any help I can get.
Little back story on me and the issues that we are dealing with...
I work on a fleet that uses Panasonic CF-20s we have about 65 of them. Up until the beginning of the year they all had warranty so all the repairs were covered. Fast-forward to now and all of the units are out of warranty and it can't be extended past this point. We don't have the budget this year to replace them, so we will be stuck trying to fix any issues that may come up.

Hi guys got a Corolla factory cd cassette player that was giving a lot of issues. It's from 06 Corolla, my friend the same unit in his corolla and he has the same issues.
1. Stereo restarts by itself (thought loose connection but does this on bumpy and non bumpy surfaces) ''ST'' letters would blink on off on the radio when this would happen.
2. Audio cuts in and out randomly for a second or a few minutes at a time.
3. Shows MTL ERROR (randomly or after turning it on) assuming to do with tape deck which actually plays.
4. Shows ERROR 3 (randomly or after turning... -
Hello. I need help opening the service menu on a Panasonic TC-59R62
Its an old CRT with bad overscan. The top left of the screen is cut out and I need to adjust it. Ive tried multiple methods online ie, holding volume down on the TV then pressing recall (with the 30m timer as well). Nothing I have tried has been able to bring up the menu if there's one at all.
Or is there an adapter I could use to fix this? Trying to use the TV for old retro games but again the top left of the screen is cut out and cant see anything displayed there. -
Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing hereπ€?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting π.
TV Model: Panasonic TC-P55ST50

Hi all
I have a Panasonic TH-65AX800A that turns on for about 2 seconds and then turns itself off.
I got it like this hoping it was just a bad cap and an easy fix.
I have pulled the power board and cannot see any obvious capacitor damage.
Is there any other likely causes? Anything else I should check for?
The power board is
TNPA5937 2P
with an additional silver sticker saying
A1318VAL
TNPA5937DA
V1434
I have tracked down another power supply which has the markings
TNPA5937 2P...
