Hello! I have a th-42px75u which does not power on but gives me a solid red light. I can hear 2 quick clicks then a third one when I press power button. With the tv plugged in I get 0 volts on pin 1 of P11, P2, P5, P6, P7 which are the ones I've tested so far and according to the schematic on the service manual there should be 15v at least on p5, p6 and p7. C611 and C446 don't look puffed but they don't look super flat either, I don't know if that's normal on such a big cap. Any help will be appreciated.

Re: Panasonic TH-42px75 Solid red led no codes
No one ever had this "Not blinking any codes" problem? Just a solid red led and 3 clicks. -

Re: Panasonic TH-42px75 Solid red led no codes
The 'clicks' suggests to me that the PSU is OK. The domed top on the main cap is normal. I would remove the jack from the PSU to the Y-sus Bd and see if Vs and Va come up.Comment

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 😂.

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... -
Hello. I am hoping the very smart helpful people of this forum can help me repair my TV. Here is the history of the what I have done so far.
I was given the TV by a friend who was going to throw it away because it did not work.
The TV definitely had a bad TNPA5349 board that was shorted across the power input. I sent it to a repair service on ebay and was told it was rare case and not repairable.
I then bought a refurbished TNPA5349. Before installing it I checked for a shorted power input and it was good. I installed it and powered on the TV. I could... -
