I heard about this the other day but didn't pay much attention. Then my 52" LCD started turning on and off 10 times when you hit the power button. Apparently they put a bunch of junk capacitors in these and there was a class action. They are coming out to do the repairs next week as part of the settlement. Thought I'd share in case anyone else has one of the listed models:
