      tom66 might have a training manual, check the little print under the sentence that says "don't pm me" on his post above, post number 18.

        ok i bought service manual for this panasonic model.



        i attached photo of connector A6 which connect power board and main board, it does look from this schematic like Power SOS signal sends Power board to main board. on pin 8, which is Power SOS voltage, I have 3v(2.96). I think if power board sends SOS signal means it is damaged, am I right ? please confirm this.

          if you upload pics. right here, its a lot better, I clicked your picasa link, they want me to sign in to google etc, if you upload directly here, its faster and easier for us to see them.

              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 hereπŸ€”?
              Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting πŸ˜‚.

              Hi all folks.

              My old Plasma TV blinks 10 Times when i try to start it. Its now 2 weeks that i search like an old donkey on internet and i try everything.

              Samsung UE75TU7020k No picture, Standby blinks 2 times
              by brithepi2k
              My Samsung UE75TU7020k lights up fine when one of the ribbon cables are disconnected from the main board, lights stay on but not getting half a picture, I do the same with the other ribbon and put the other one in and lights stay on but not getting half a picture. The standby light flashes 2 times then reboots then it then tries to come back on again and just keeps looping until I take either one of the ribbon tables out (doesn’t matter which one I take out it stays lit when either one is out). I’ve tested the backlights but all working with none shorting out, I’ve replaced the main board...

              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,...

              Samsung UN70NU6900FXZA - Red Light Blinks 2 Times Then Screen Flickers
              by Samunggg
              I've happened upon this TV, it came with no power cord or remote and it seems to be experiencing a common issue where the red indicator light blinks 2 times then the screen flickers as if it's trying to turn on. No picture, no sound. I suspect the functions of the TV are in good order and that the underlying issue is with the power button which is missing. It's just a white tab where the button should be which means I can't cycle it.

              I wanted to know if there is anything I can do or if I should just get a replacement module with the hopes it will fix the system. Alternatively if...
