Re: 4 Blinks Panasonic TC-P50G20 Help to target the problem.
Unplug the tv and wait 10 minutes. Unplug the connector going from the power supply to the SC board. Plug tv back in, turn on and see if you get 7 blinks. If you do, the SC board is bad. They are very hard to find. You must also check the upper and lower buffer boards.Leave a comment:

4 Blinks Panasonic TC-P50G20 Help to target the problem.
Hello everyone, I have a panasonic tc-p50g20. There was some flash of electricity and after this event the TV began to flash 10 shots. However, when I press the power button after the relay clique when reconnecting the TV, it flashes 4 shots. So I followed the troubleshooting guide for the 4 blinks. The last test gives 3.3 volts on pin 9 of connector P7. Subsequently, he tells me to change the P-Board.I would like some help in targeting the problem component on the P-Board. By the way, The VSUS and P15 is dead. By cons, I did the different test the Short for VSUS VDA and P15. No results below 1kohm.Thank you for your help.Jeff

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 😂.

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... -
Hi,
This is my first post in attempting to keep my beloved 2013 Panasonic plasma tv going.
About 6 weeks ago the tv was turned on but then immediately shut off. There was no recent power surge or popping noise or any other symptom.
I checked all of the obvious things and decided to try a replacement power supply board (PSS in Panasonic lingo).
I would like to check the Vsus but this is one of the final models and at that point Panasonic did not indicate the Vsus and Vad voltages inside the chassis. It looks like they were discouraging people from making adjustments.... -
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,...10-30-2024, 10:09 AM -
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...
