Try this:
Access menu service by press on your command, with your TV OFF:

INFO + MENU + MUTE + POWER ON

Then you should get access to Service Menu.

The last item says: RESET

This will do a reset to the TV.

Make no harm.

WARNING: If when on service menu you feel tempted to "screw" on anything FIRST take note on ALL you change! You can compromise the TV ...

R U using HDMI? If so that be the problem.

I had the same problem and I replaced the t-con board. My t.v. is fixed!!!! I just couldn't see spending another 700.00 dollars for a repair shop to fix it. The t-con board is located at the top of the t.v. once you remove the back cover. Be very careful removing the two plugs at the top of the board which was easy once I figured out how the clips worked. there is a black lever like connection which flips up, then grip with your fingers the tab and slide the tape like wires straight out. The bottom plug is very simple. Also to expose the t-con board you will have to remove a heat shield cover. Once removed there is foil looking tape that needs to be peeled back to expose the board. The board is very sensitive to static electricity so if you have a grounding strap that you can strap to your wrist and ground to the frame while performing your repair. Its best to lay the t.v. face down on the kitchen table with a blanket to protect the screen. Good luck!

I just fixed this very same problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.
