    panasonic tx-p50gt30 8 blinks afrer 7 blinks repair

    Hello again.

    I have a little problem with my tv: it had the 7 blinks failure, and I repaired the SC board. After that, it starts for 1 second and goes to 8 blinks. Everything on the SC board looks to be fine but I discovered that I have one shorted transistor on the SS board, Q102. I have a new one but I am wondering if it would be better to replace also IC 191.
    I did not check the SS board before the 8 blinks. Do you think it's possible that it went off together with the SC board or it died after my repair?

    You should be fine with replacing Q102 only. I've had this fault myself.

      Ok, thanks. I'll give it a go.
      Have you found the cause of this double failure?

        Just the loose screws that mount the boards.

          Yeeeee! It's alive!
          It was only Q102 on the SS board.
          The SS screws were not loose. On the SC yes, they were loose, almost all of them. I had some screws with washers and replaced all of them.

            Good job! Those damn screws have kept a pretty good supply of cash coming my way.

              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 here🤔?
              Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.

              Panasonic P58V11B 8 and 12 blinks error "fix"
              by Biruslapio
              Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.

              Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner...

              Panasonic plasma TX-P42ST50 - 6 blinks
              by jm1234
              Hi,
              anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
              It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
              I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
              I checked that board for any obvious faults...

              Panasonic Plasma TH-50PZ85U No screen No blinks on red power light
              by Alicat
              Hello,

              Stopped by this site trying to fix my parents Panasonic Plasma TV.

              Model number is TH-50PZ85U

              Power comes on and the red power light stays on solid.

              Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.

              I also hear a few clicks.

              I also think my parents said there was a thunderstorm and the TV failed after that.

              Section 6 in the service manual talks about power and no screen,...

              Looking for assistance troubleshooting a Panasonic TC-P65ZT60 with 3 LED Fast Blinks
              by CrewmanRedShirt
              Hello all,
              As the title states, I followed the troubleshooting guide located here: https://www.manualslib.com/manual/23...page=53#manual, which concluded the 'A' board needs to be replaced. Looking around the net and eBay, I see that there are repair services for the board (TNPH1043UE? Not sure if it is a 'UE' as the suffix grid does not appear marked). What additional troubleshooting can be performed to ensure 1) this board is the problem and 2) since there are repair services, what are they fixing on the board?) I expected 3.3V not to be available anywhere...
