Sharp Lc C3234u Buttons Don't Work.

I have a Sharp LC C3234U and the button to turn on the TV works, but none of the other buttons located on top of the TV work. The volume control button will automatically take the volume down to -0-. If you turn up the sound, it automatically goes down again. Is there a board that can be replaced where the buttons are or is this hopeless or too expensive to fix?
