If I am right, this is an expensive problem.
The minute pixels that make up the display are turned off and on by circuits arranged in an X-Y matrix. To avoid using one circuit to control each pixel, the circuits are rapidly scanned at a rate higher than the eye can detect.
One or more of the circuits that do the scanning have failed on your set and the ugly part is, the display panels often have these mounted on the display itself forming a 'package' that speeds assembly and are made only by a few companies. If yours is one of these, the entire panel would have to be replaced since the integrated circuits used are very small and have pin spacings that pretty much preclude replacement by hand since they were originally placed by robots.
I hope for your sake the display panel and its control circuits are separate and the panel is still fine since the cost of an integrated replacement may prove to be about 1/2 to 3/4 of the cost of a new set.

I had the same problem. I bought the TV with the same symptoms and couldn't find a solution. So just on a hunch I tried different button combinations on the front of the TV while I turned the main power switch on in the rear. One I got to the Channel up and Channel down the TV came to life and works great. So just hold those 2 buttons down at the same time while you flip the switch on the back. Hold them for about 10 seconds and then you should be good to go.
