My tv had been working great. I went on a month long business trip and when I got back I don't have a picture...initially when I turned it on the screen remained black and a blue LED light near the power button on the tv would blink 8 consecutive times.

I unplugged it for a day and tried again. Now a message pops up on the screen stating the the display is "starting up" but the screen then goes black and the blue LED blinks 12 consecutive times. Any ideas?

There's someone selling a repair service for this issue on eBay.
