We have a pioneer plasma tv and there was a loud

I had the same thing happen a few weeks ago to my zenith 50" plasma tv. I tried to turn it back on with the remote and the power button on the set but the only thing that happened was the led would flash green 3 times and then go back to red. I took it to a repair shop and they called yesterday to tell me it was going to cost $700 to fix it by replacing the power supply. No guarantees either that it will last any longer than the 3 years I've had it for either. But it's still cheaper than replacing it with a new "bigger" tv which is what I will eventually do anyway. I've heard of people looking on ebay for repair parts and doing the repairs themselves but there is no warranty on human error...
