My Sharp is trying to trick me!

My Sharp LC-37HV4U flat panel has decided not to work. It had been working fine for years then one day I turned it off before leaving the room and 15 minutes later came back and it wouldn't turn on. I tried unplugging it and letting it sit but I still got nothing. The little red power led now just slowly blinks on and off. I read some previous post on here and tried to hold down the input and volume- buttons while powering it on and that would turn it on with perfect picture and sound. However, as soon as I turn it off to exit that service menu it won't turn on again until I enter the service menu again. It seams like it "CAN" work but just doesn't "Want to". What do I do next to narrow down the real problem. FYI I can use a multimeter and solder, but have no real experience repairing tvs. Thanks for any advise you can give.
