I would suspect the Y-Driver PCB. When viewing from the rear, it is the first board on the left which connects to the Panel.
The IC on the bottom of this board has most likely failed.

I have no idea about the EEPROM. I don't do much tinkering with the Main PCB unless I find a faulty regulator. Other than that, I generally just replace the entire board.

Your right rufa33. After some review of your model, I see that it does in fact have a separate analog board.
I would first make sure all of the connections are seated properly. If you still have...

If the image is freezing or blacking out, and it is not a signal issue, I would suspect a bad Main PCB.

True. I believe Windex was used in the pic I posted. However, water will corrode the electronic connections as well. The connections will corrode worse/faster with heat (e.g. with the set on).

Unless any possible corrosion can be removed, the LCD is most likely junk/unrepairable.

The problem is most likely a loose tab bond (factory bonded ribbon cable) inside the LCD panel. Heat will cause materials to expand while lack of heat will cause them to contract. In either case,...

I am guessing that he will replace the Main PCB. He should have one with him, along with a power supply when he shows up.

Those key voltages all seem to be correct. There is another voltage I would check. On some panels it is called VDA. You should be able to find it at the bottom connector of the X-Main. This voltage...

Yes, that's one of them (VS). I assume that is the X-Main in the picture. The Y-Main also uses VS.
