Query: Very Disappointed

I bought a Vizio VP50 about 20 months ago. The picture goes out of control and eventuall goes black after it's been turned on for 10 minutes. Vizio techs seem to know what's wrong and estimate it will cost $578 dollars plus to repair. Sorry, but I'm going to go out and buy a different brand. If you buy Vizio, you better also buy the 2 year extended warranty plan and make time for repair service down the road!
