My Mitsubishi 55613 won't come on. It was working fine Sunday, but when I went to turn it on Monday night to watch Heroes it wouldn't come on. The green power light (which blinks slowly when tv is off) came on when I turned on the power like always, but after a few seconds the light started to blink rapidly. It usually blinks like that if it loses power. So, I waited a few minutes for it to stop blinking. When it did, I pushed the power button again and then it started blinking fast again, but this time it didn't stop. I have tried unplugging it for a while, plugging it into a different socket, and I've pushed the reset button on the front, but that light just keeps blinking and tv won't come on. It is plugged into a Monster Cable surge protector and everything else that was plugged into it is fine. Its a RPTV and its only 3 years old. Any ideas whats wrong with it or what it might cost to fix it? Any help is appreciated.
