Is your audio coming through the TV, or a secondary source like a tuner? Try the menu button on the front. If the menu does come up, then your problem might not be the TV, but the source of the video.

If your menu does not come up, then your display may be shot.

SINCE THE AUDIO IS OK SO THE PROBLEM COME FROME VIDEO STAGE TRY DIFFERENT SOURCE OF VIDEO IF PROBLEM PERSIST IN THIS AREA ONLY OF SATALITE
SO THE PROBLEM COME ONLY FROM THIS STAGE ONLY OF RECEIVING SATALITE THE GOOD EXPLAINE PROBLEM EXPLAINE THE SOLUTION
THANKS
