You may have dying power supply module, that will be the first place to check.

It can be due to unstable DC power from the power supply due to bad caps, or bad main board (I had to replace my main board, and later on the inverter boards). You may want to think about putting money into this TV.

I had a similar problem with my Phillips 42 in. LCD HD TV.
Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.
Hope this helps

I just fixed mine, I am not exactly sure what did it, but I held the power button down while pushing and holding each button for a few seconds after going through each button I unplugged power cable and then plugged it back in and it powered it up and it worked
