    Panasonic TC-P50UT50 A Board repair?

    Hi all, so I have a 2012 Panasonic TC-P50UT50 with the 13 lights flashing (confirmed a dozen times it's 13 flashes and not 14 flashes). Google (and repair documentation) say it's a A Board replacement. The TV is turning off and on on it's own and now and then clicking, with some weird lines horizontally.

    I have already gone ahead and replaced the whole TV with a new 2021 model (for my wife, it's hers in the living room), but I am extremely bored these days with camping season over, so I would like to try and take this on and try and repair it.

    I have some experience at fixing consoles, and other electronics needing soldering (not phones yet), but this will be my first crack at a Plasma TV.

    Replacement A boards are nearly impossible to find, and those available are just not worth buying, (especially with me being in Canada) so my thoughts are to remove the A board and actually try and see if I can find out what went wrong.

    My question is, although I know the SC boards have been fixed by many, has anyone ever fixed an A board on one of these.

    I have not taken the back off yet, but curious what I could be in for.

    To clarify, I don't expect to fix this, mere practice and something to do, but hey I would like to at least try.

    Thanks for any help.

      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
      by Tynan Dill
      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

      Upon bringing it home and plugging it up, it showed a standby light.

      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

      The screen seems to blackout and stay black, but with a flashlight I can see the display.

      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

      HP Pavilion 15-eh Board DAG7HAMB8F0 - CPU throttling to 0.4GHz (PROCHOT_EXT) and black screen
      by m1ch43lzm
      Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
      Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

      Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
      by sam_sam_sam
      I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

      This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

      After all of...

      Panasonic TC-P54VT25 No image. A or D board?
      by canadaboy25
      I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

      The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

      I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...

      TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
      by howardc64
      All left and right refers to looking from rear of TV (or looking from front with TV upside down)
      • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
      • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault
