xcuzme222,

I'm sorry to hear that you're having this issue.

It may be the input board, but first, try checking the resolution on your cable/sat box to make sure that it's sending a HD signal through the component or HDMI output. If the problem was with the screen, the menu wouldn't come up clear, but also be pixelated.

If the box resolution doesn't help, you might want to have your unit inspected by a technician.
