Help with Toshiba 55" flat screen. Blinking light, shuts off.

[yankeefan22408]

I have a Toshiba 55" model 55L621U TV. It's always has restarted itself intermitantly while watching it. But the other day while it was on, it shut off and wouldn't turn back on. I unplugged it, and plugged it back in several times. Each time, the splash screen comes up, the red light blinks about 4 or 5 times, then the TV powers off. I'm guessing probably one of the boards went bad (of course it's 2 years old and out of warranty). Can anyone help with which board that needs replaced? Thanks in advance...

Did you find any resolution? Was it the main board or LED strip?
