    TC-P55S30 7 blinks problem

    I saw a similar thread to the one I'm about to post but it was a different model number. Originally had 7 blinks, replaced sc board and i heard a loud pop and the set went into a 14 blink error. I then sent my original SC board in for repair as well as SD/SU boards. They fixed my SC board, no more shorts and they informed me that one of my two SU/SD boards were bad (can't remember which). So I then replaced the bad one before putting my fixed SC board into the set. I went to power on and i no longer get any blink code error but the set refuses to power on. I can hear a buzzing noise over some of the boards as if the tv is working, but i have no picture on the screen. I went from 7 blinks to 14 blinks to none. I'm getting frustrated and confused Any ideas of what might be wrong here guys? Thanks so much in advance!

      cardinal sin i'm afraid. Always check buffers before replacing the SC. It's tragic you found us after the fact, we would have kept you on the straight and narrow.

      Who did the Sc repair?

      Post a picture of how all the boards are hooked up especially the Sc,SD,SU

      Did you notice if an onboard green LED was lit whilst you had the buzzing?

          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...

          Problem with LG Plasma 60PM6700 - Random power downs
          by theone111
          I have an LG Plasma TV 60PM6700 for the past ~12 years.

          In the last ~3-4 months I have been having some issues.
          1. Problem: It started with random picture disappearing (sound still worked).
            Frequency: Happened about once a week.
            Solution: Had to turn off TV wait a few seconds before turning it on again.
          2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
            Frequency: Happened about once a week.
            Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
          3. Problem: TV shuts down

          Hp DAOP5FMB6A0 blink caps/lock problem
          by dclass-pro
          Hi guys, I have an HP model 15s-eq1040nl main DAOP5FMB6A0 REV:A with a caps/lock 5 long 3 short led flashing problem, I tried to remove the battery and program a new bios and when I restarted it immediately worked correctly, the pc turned on and loaded the operating system.
          As soon as I turned off the pc and connected the battery, the problem reappeared... caps/lock 5 long 3 short led flashing again!
          the battery was dead, i charged it and it works fine, but the pc won't turn on again.
          What do you recommend me? Do I have to redo the bios or is there anything else to check?...

          Thinkpad X1 Carbon "LMQ-1MB 12298-2 48.4LY26.021" VCC3M problem
          by Zeonalbasta
          i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
          The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...
