My tv worked fine for years and now all of a sudden it went of. You try to turn it on and nothing happens. I unplugged it and let it set over night and when I plugged it back in it worked fine for about an hour then it does the same thing.

These DLP tvs sometime u unplug suddenly and replug it back wright away,tv will go into protective mode and will not work wright away.Tries tv unplug,replug it back about an hour later,now the tv will reset itself back to the factory setting.The tv should work now.
Tries unplug,replug an hour later.Still no power than.Ur power board is dead.Tries websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.
I had a similar problem when there was a power outage or the lights went briefly out. I unplugged the TV and left it for a few days/weeks and then plugged it in and the TV worked. I think newer TVs should be treated like a home computer and put them on surge protectors.
Most likely it's your memory ic (eprom). Sometimes depending on the make, an authorized service center can flash the eprom back to normal. This is something you can not do but I hope this helps a little.
I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.
Unplug the set, remove the back and follow the power cord onto the main board, where you will see a small glass fuse. Replace that fuse with a new GMA 6.3 amp fuse. I have seen many of those fuses in Panasonics "pop" for no apparent reason. If that does not fix it then replace the back and have the set serviced by an experienced tech.
