Bright white screen with faint images
I suspect a lightening hit. Audio is fine, channel selection is fine. Screen is bright white with very faint picture images (almost look like negatives).

If lighting did strike, you would be suffering power supply problems, due to a power surge from the strike.
The problem sounds like it could be related to the LCD panel becoming faulty or if your able to test inside the unit with a multimeter, you can measure the voltages from the printed circuit boards, especisly those suppling power to the LCD panel as well as the Logic PCB, A small printed circuit board you will find either attatched to the LCD panel. I hope this helps.
Good luck.
