my tv will work for a while, then all of sudden it will shut off, reboot it self this time staying on a little less. It will then freeze until I unplug it from the wall and let it sit for a while and do the process over again. I looked for bulging caps didn't see any, I understand that don't mean any are bad. But would a cap do that? seems to me its a heat issue. I just don't know where to start. thank you in advance

Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.
Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner... -
Hello,
I'm trying to fix a TV that got damaged by rain (open window during a storm).
The TV at first would start up and work completely normal, with no lines on the screen or anything. But after about 30 seconds, it turned itself off. After it shut itself down, starting it up directly afterward is no longer possible.
The standby light is red and it blinks once on the power-on command by the remote. The relay also does not click anymore when plugged into the wall.
Standby voltages are all present and stable, approximately 13V for the 20V line... -
Hi guys!
I'm in need of some support so I can try to fix my laptop/gpu.
While I am a cerified automotive mechatronic, I have only basic understanding of electronics repair and identification.
I'd like to identify the issue and replace the specific component myself to learn about electronics and expand my skills a bit.
No better time than now, when my laptop, Alienware 18 from 2013, shut down when playing and refused to start again.
I know about electric diagnostics in and about cars, but I've never dabbled with electronics.
However, I know... -
I recently got my hands on a 60" Panasonic P60ZT60 plasma tv (european model) that has some strange issues along with an 8 blink code.
It know this tv is getting old but it was once considered one of the best plasmas ever made, and i think it is still holds on to that even by todays standards.
So, long story short. When i first got the tv it had a very bright washed out picture with very raised blacks in all picture modes and i couldn't find the cause in the picture setting menus.
After doing a factory reset this problem was gone and the picture was back to...01-06-2025, 06:02 AM -
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 here🤔?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
TV Model: Panasonic TC-P55ST50
