After watching some youtube videos and checking some forums, I'm at a loss. With both ribbon cables connected, we have no image. With the left one pulled out, the screen is black and white, split down the middle. With the right cable removed, it is all black. Backlight is working fine and we have sound and can open applications. We are strapped for money right now and are hoping to repair whatever the issue may be. I think the TV was manufactured in 2012, so I'm aware that may not be possible. Edit: Found a single vertical line of blue pixels on the left side of the screen with one of the ribbon... -
Hello, got a ST50 plasma TV for repair. No signs of life, not even blink codes. Opened it up to check the power supply, type MPF6914. Apparent issues from visual detection and measuring for shorts:
Diode type G972s6 - D101 with a short
Mosfet 06N90E - Q301 shorted
Fuse T5AH 250V - F103 blown
Diode D301 shorted
Relay DG1U-17VDC II - RL001 blown
I have not found a circuit diagram. Maybe someone here already dealt with a similar issue? Thanks for tips where else to check π... -
Hi,
the TV has a black screen. Sound OK, backlight OK.
When I measure T-CON voltages, there is VGL+VGH=0V. After unplug the right side of the screen from the T-con, voltages are OK and half screen works normally.
I tried to search for any kind of short on the right side, but I had no luck. I have a beginner experience in measuring and repairs of the LCD panels..
Thanks to anyone who can guide me in solving the problem.. and be patient with my english ππ -
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 hereπ€?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting π.

Hi all,
I have here a Plasma TV TX-P46G10E that before had a problem where it had issues with 11 blinks (FAN SOS) BEFORE starting normally. After that it works for all day long.
It had some bad cold solder and I remade them all. After I replaced a fan that was half-dead (no RMP signal from the respective pin, but ok with 9V).
Now the TV power up instantly and works perfect... only without the backplate!
If the backplate is placed on the TV shutsdown after about 10min and start blinking with the 11 blinks. If I shutdown and re-powerup it starts blinking after a bunch of...
