Re: Hitachi P50V701 (possible buffer issue)

I have a Hitachi Plasma 55HDX99 that the top half of the screen had vertical lines. One day the tv didn't start up no sound nothing worked. It sounded like it was trying to power up but didn't. Pulled off cover, the night ridder lights all blinked in sequence and turned off. I pulled the upper buffer board and the Tv started up and the bottom half of screen was perfect/ the upper was black. Put the upper back in and the TV wouldn't start and had 8 blinking blue lights. Is the upper buffer just bad or could it be more?
