I've had this TV for awhile in the bedroom hooked up to cable box with HDMI 1. Over the last year I've noticed (progressively getting worse), it loses connection with HDMI (No Signal message), mostly when first turned on from cold, but lately anytime. It will start by flashing a black screen and then go completely black after a minute or so. Unplugging HDMI cable and back in will normally make it work again.
I thought it was my cable box but after trying new HDMI cables, the 2 other cable boxes in the house, and the Playstation 3, I had same problem. All HDMI ports also do the same thing.
So I'm convinced it's the main board, which had been repaired before (but for bad EEPROM).
I have to open it back up for some pictures which is a hassle on this one.
Any ideas what would cause this?
HDMI Switch IC?
