Try in any other power outlet.check out if the wire got cut or loose any where also look at the power led on the front pannel if its not comming on totally then it might be just the fuse got blown problem.other wise can be the problem of internal main board that has to be checked properly.

Search internet for a solution. Called the Repair Center for the Company I had purchased the TV from. I have a 5 year warrenty. I thought maybe there was a quick and simply solution but I could not find one. Thursday Repairman is coming.
I had the same problem. The repairman said the Convergence ICs were bad, located on the big aluminum heat sinks on the center board in the TV. He replaces both, and a couple of fuses (that look like resistors).
The tv worked fine for a couple of days then did exactly the same thing. They are coming back out to fix it next week. If there is anything different, I'll post an update.
IFyou feel confident and can locate switch mode power supply with back removed.
Try warming switchmode power supply before turning TV on.
If TV turns on normaly then there are some small capcitors that are a common cause of this fault.
Otherwise look for DRY or CRACKED solder jointson PCB
BUT DON'T do any of the above if your are not confident send it to a TV repaiman.
