I picked this up from a friend. It's not economical to fix, but since the panel was cracked, it is now dark and the 7 blink code is all I get from the unit. Is it likely all the boards would be good for parts, or could the panel crack have damaged one of the buffers or other? Thanks!

Re: Panasonic TC-P60U50 7 blinks cracked panel?
The panel crack has probably damaged the buffers. You can however test them:

In your case, you can use the screw marked HV DANGER and the output ribbon connectors.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Thanks Tom! I think I've seen this video before
What specific boards stand to get damaged in a panel crack?

Usually only the buffers and then only some of the time; everything else survives.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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... -
49UJ6500 LCD panel has a lighter band on top when first powered on. Goes away (or gets much fainter) after TV on for a few min. After powered off for awhile and power back on, same band appears. If powered on immediately after powering off, no or much fainter band. Running the latest firmware.
Disassembled the TV and lifted the LCD panel during testing. Band is on the LCD panel (can see the band on the panel as I lift it slightly) Backlight is perfectly even at the top edge. Double checked LCD panel alignment in the frame and is perfect but since band moved with the panel, its on... -
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 -
TV flashes backlight then reboots over and over. no image. Client said it used to have image for a bit before rebooting. Got worse over time.
tcon is built into mainboard.
Only one cable goes to panel boards.
there is a cable from one panel board to the other that links them.
cost cutting measure that results in us having harder time to diagnose.
removing the link to the second panel board allows TV to stay on with stable backlight but no image.
used cut off tape method to mask 1 maybe 2 pins on the side of the cable that goes to that second panel board....
