Set was manufactured in 2012. I'm trying to diagnose where the problem is. I am assuming it is over-currenting after heating up? Display looks fine until it decides to shutdown. If I keep turning it on, it will eventually refuse to power up and requires unplugging to get it to respond again.
I originally thought there would be some easily detected bad electrolytic capacitors, but I don't see the telltale signs. There might be some very minimal bulging on one of the x buffer board. BN96-22092A (LJ92-01852A).
If I unplug the power feed to the X/Y board (LJ92-01854B), the... -
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 here๐ค?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting ๐.
TV Model: Panasonic TC-P55ST50

Good day folks. I wasn't too sure whether I should start this discussion just yet, because I feel I haven't dug deep enough, which I can't do until Monday at work, but I eventually thought I'd just go for it so by the time people start joining in, I'll hopefully be able to complete my measurements.
TL;DR - Panasonic KX-NS500 PBX sometimes dies - PSU issue (schematic attached). 41v rail drops to 25v and 15v rail goes off entirely. Often, even a power cycle doesn't restore it - main cap (C4) needs to be "manually" discharged for it go gain.

Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in... -
The model is 15ec-1061nm
Board number is DAG3EDMB8D0โ
SO i turn the laptop on , and as soon as it starts booting from disk, from usb, windows,linux,HBCD,anything i boot it just turns off....while in bios menu or in linux boot menu it stays on normally...It's like when it starts to use graphics it shuts down...But i measured 0.72V while working on the GPU power line,no excess heat is comming from GPU or CPU, i even removed the heatsink and turned the laptop on and everything worked fine, got a bit hot, fan span to full speed, but it worked like that for few minutes in bios...10-29-2024, 12:05 AM
