    Panasonic TX-P50U20B - hours logged before failure

    I recently acquired and repaired a TX-P50U20B and checked the hours usage in the service menu.

    For an 8 year old tv it had clocked up an impressive 37,000 hours plus - that's over 12 hours a day, every day before it failed.

    That despite the fact it's the base 1080p model with no cooling fans and no heat sinks on the Y buffers and the notorious TNPA5105 SC, which was the failed part.

    Anyone seen higher hours before failure?

    Panasonic TC-P55ST50 8 blinks then no blinks
    by Andre Gilbert
    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 here๐Ÿค”?
    Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting ๐Ÿ˜‚.

    TV Model: Panasonic TC-P55ST50

    Problem with PANASONIC CF53 laptop after changing BIOS settings
    by AquaMan Ua
    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...

    LG 49UK7550PTA - after couple of hours screen starts to blink
    by JohnML1975
    Hello Forum team

    Have this TV; searched for the model and could not anything so thought I would share in here

    Had an issue, some years ago, and looks like some placed sticky tape over some of the lines on the FFC cables between the T con and the mainboard
    Anyway, the owner, who gave me the TV, says it starts to blink after a few hours

    So I removed the covers, and could not see anything visibly
    Removed the power supply and thought some of the solder joints, on the hot side, were not the best. I thought some looked like they were cracked.
