Hi i was hoping someone could help me with my problem?

I have a Hitachi 55" Plasma television that I am having a picture problem with, Im hoping someone can help.?

• The issue I am having appears to be that my television works for about 30-45 mins when i turn it on, then randomly, it turns the picture off. Another odd part to this is that I still have sound, but the picture is gone. I have found that if I turn the television off for a few minutes and then turn it back on, the picture is back for awhile again, but turns off again within another 30-45 mins. I have a Hitachi 55" Plasma, Model #55HDT79. I have read up on a few things but cannot seemingly come to a conclusion on what may be going on. Can anyone give me a suggestion, a website to visit etc... that may be able to help in curing my television. I appreciate any and all advice, and please if you need any more information just ask! Thanks!

• Answer:

  There's no easy button on this one. You'd have to measure the voltages with the set on after the picture disappears to find out what voltage your missing. I'm just going to pick on the main digital board. It's #JP50763 list $190 say $100 labor so $299 plus tax so over $300 to fix. Do you want to stick that amount into the set? You can buy a 50" for $500/$600. The set is almost 5 years old. It's like putting a new motor in a car that has 188,000 on the transmission.
