I have a 42" Hitachi Plasma TV. Every so often, but more often than not lately, it won't turn on. The red standby light is lit on the front of the set, but no matter what I do it won't come on. I've tried unplugging it and plugging it back in, plugging it into a different outlet (although everything else that gets plugged into its normal outlet works just fine), turning off the main power and turning that back on... nothing seems to work with any regularity. I've been trying to turn the TV on for over an hour and it won't work... any suggestions?
