    Panasonic plasma TC-42PC2 single blink = bad "A" board (equiv TC-42PX24)

    I picked up a 42" Panny TC-42PC2 plasma (mfr late 2010) a while back for next to nothing and it had no picture with a single blinking red LED power light. The 6, 7, and 10 blinks are well documented but single blink not so much. Fast forward to a few days ago when I came across a TC-42PX24 with a broken screen and bought it for even closer to nothing. Turns out these both use the same panel and boards with the main (only?) difference being that the 42PX24 has an anti-reflective (AR) glass on the front. I swapped the A board which is the board with all of the inputs and my 42PC2 is now working perfectly. I wanted to document this fix so others searching might stumble upon this thread.

    Now, my curiousity has me wondering what it might have taken to fix the A board if I had dug into it. Not sure it is worth it now. I'm expecting that I can sell the power supply and sus boards to more than cover what I have into this entire project so maybe I'll just throw in the bad A board for free to whomever buys the other parts.

      The A Boards are a very common failure on this set. Apparently a combination of BGA bond failures and sometimes a voltage regulator failing.

          Panasonic ZT60 plasma tv with strange behavior and 8 blink code
          by cloo
          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...

          Un50cu7000 2 blink oddity *partially solved
          by EazyBone
          I write this to maybe help another with this TV.

          So I aquired this TV a 2023 model. It started the 2 blink reboot problem which indicates bad panel. It was still under warranty and the repair man came by.

          The Samsung repairman brought a brand new panel and switched my original boards to the new panel. The new panel then had the 2 blink error code. The repair guy said he has seen this and the MAIN board on this model will cause the 2 blink. He then replaced the main/power board (they are both connected) and put it back onto my original panel. Voila it worked.

          panasonic TX-P50V10E 6 blink led problem
          by Vebririon
          Hi everyone,

          I'm new here and trying to repair my Panasonic TX-P50V10E plasma TV, which is currently showing the 6 red blink error code.

          Just for context: I'm used to building PCs and installing modchips in old consoles, but this is my first time trying to fix a TV. I'm French, and while my English is okay, I'm using ChatGPT to help translate and clarify my messages as much as possible — so please forgive any odd phrasing.

          I'm also not very experienced with using a multimeter, but I'm very motivated and ready to follow instructions carefully and report...

          Pioneer Kuro Pro 111FD 8 red blink error

          Pioneer Kuro Pro 111FD 8 blink red LED.





          I have been trying to solve the power-down 8-blink red LED problem with my Pioneer.


          So far I have replaced the power supply board, and the digital assembly board, I have reconnected the ribbons to all boards, ensuring the connections are good. Even though the problem is the 8 red light error and not the more common 8 blue light error code, I had Kcrownie,
          based in North Carolina replace the chips that cause the 8 blue LED problem (the main board and audio board) the plasma is still powering...

          Panasonic TH-42PZ800 8-blink error mystery
          by nervx
          Years ago my tv gave a 7 blink code which turned into 8 during diagnosis. I had ordered a replacement ss board but somehow the tv started working again and i never used the board. Now a week ago my tv flickered and shut off at random and gave the 8 blink error code. The same issue it had all those years ago. The only difference this time is that over the last few months there has been some purple and green tinge that comes and goes in more solid colors such as white.

          Anyway i checked all the screws and replaced the ss board with a known good one and still got 8 blinks. I saw a...
