Re: 55 inch Plasma Viera (VIERA TC-P55GT30) not turning on. 7 blinking red lights.

I also had the seven flashes of death. First tried the "unplug for a couple minutes, replug and hold down the power-on button (on the tv) for a few seconds. That fix didn't work for me. I heard these tv's are notorious for the loose screws shorting out the boards, so figured that might be it. Also heard that you can get a new screw set with locking screws. So hauled the tv down to the repair guy. Turned out it was the IC (signal processor). I got him to replace it AND put in the new locking screws...
