No blinks but this is what I get on screen when powered up. Any suggestions? Set was made in 2005.

This would have me thinking this could be a y sustain problem. The control board is obviously getting some information.Did I leave the soldering iron on? -

Re: Panasonic Veira TH-42PD50U
Moved cable and cleaned plugs and sockets on both end while I did that--no change.Comment

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 😂.

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... -
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, I've had this TV for 3 years, 2 years ago it stopped working signaling 12 Blinks, SOUND_SOS according to the service manual.
It has no VSUS or VDAT, and P15V has 1.0V instead, the same 15V goes to A board. F15V is ok and other main voltage rails.
It seems the power supply is defective, since unplugging D20 ribbon cable that goes from D-board to SC-board makes the behavior change, the TV stays on, there's no image nor VSUS, but 15V reads 2.4V, high enough to not trip the SOS 12 blinks, so it stays on, fans do not spin but I left it 2 hours, green led lit up...
