My daughter's X-Box causes the TV to cycle up and down as if the TV's vertical hold is not working. It happens whether there is a game , dvd, or music cd in the drive. Actually it occurs in the menu screen even if a disc is not in the machine. We know it is not a problem with the TV. Is there a quick fix? What do I need to do to fix this? Thank you for any info given. Cheers.

I know it may cost you a little, but try getting a new AV or RF adapter because there is a chance if all else fails, that your video display is failing in your old AV or RF adapter.
