Good morning, everyone.
My Panasonic TX-P42GT20E 3D Plasma TV, which I used for my PS3 in 3D, has stopped working. The screen turns on, but there is no video signal, I mean no display of the current source, audio volume level, or system menu.
The TV receives signals from the remote control (the LED flashes), but nothing happens. It won’t even turn off. I can only turn it on and off using the main power button.
I managed to trigger the diagnostics; the LED flashes 13 times, which indicates a critical error on board A—the board with the main processor. I can provide the service manual if you’d like more details.
Does anyone have experience with this device?
I’d like to remove the board from the TV to take some measurements, but I have no idea how to power it since the connectors are all proprietary and I don’t have an external power supply (which I could buy).
I found a replacement board on eBay, and even though it’s a bit expensive (70 euros), I’m considering buying it. I’d still like to try repairing the damaged board (I’m just an hobbiest), though. The board code should be TNPH0899 or TXN/A1NBUE.
Also, in the attempt to put out the board, I cut the flat cable connected to the Satellite tuner (which I do not use) with my finger. Do you know where I can find a compatible flat cable? Maybe one of these Chinese companies like PCBWay could be able to replicate it?
Any suggestions?
Thanks, everyone
AI: Have you already checked any voltages or done any measurements on the power supply/A-board (for example standby 5 V, Vsus, 15 V, etc.), and did the fault appear suddenly or after some event such as overheating, storm, or previous repair attempt?
no
AI: Can you share the exact part number/revision written on the A-board and, if possible, the markings/part number on the cut flat cable or its connector? That would help people confirm whether the eBay board and a replacement ribbon cable are compatible.
The board code should be TNPH0899 or TXN/A1NBUE
The code on the flat cable is not readable but I can upload a photo
