My 42 inch plasma TH-42PX75U has lost its picture. There was a spike though the cable coax during a storm that affected every piece of connected equipment. The cable box and surround system were both repaired under warranty. The television simply will not display a picture. The set will come on, and all of the on screen menus will show up, display and function, So I believe all of the backlights, panel, etc are fine.. Non of the external inputs or tuner will produce a picture. I tried replacing the input/output board, but this did not fix it. Could it be the main system logic board, does it have a signal processor on it or something? Any other ideas?
Thanks so much in advance.
Dave
