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... -
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... -
Hello,
I have a Panasonic TC-P50U50 plasma TV which powers on briefly, then powers off and flashes the power light with 8 blinks. This TV is infamous for this, of which the suggestion that the SS board has failed due to loose grounding screws and requires a replacement of the following components on the SS board:
2x DG302 (Q16051)
2x RF2001 (D16041)
2x 5.6 ohm SMD resistor
1x BD8694 IC
I have already gone ahead and replaced these components, as well as cleaning off the ground connections on the SS board as well as the associated...
