Last night I was watching TV just fine. I turned off the TV when I went to bed and then tried to turn it back on this morning when I got up. It wont turn back on and I have checked to make sure that there is power to the TV.

Check ur power source?Tries tv unplug,replug the tv back like about an hour later.Now the tv are resetting it self back to the factory setting.The tv should work now.If still have the same problems,some how ur power supply board is causes and is not providing the tv the wright voltages anymore.That the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
