How can I Fix JVC XV-F80BK Component and S-Video distortion?

I have a JVC XV-F80BK DVD/CD 7-disc changer/player. The Component and S-Video outputs are distorted like the tracking on a VCR was off. Very wavy black and white picture can barely make out whats playing also does this with out playing a disc. Haven't checked the composite video output and the audio is fine. I would like to fix it rather than replace it. I am an electronic tech. but don't have all the tools needed at home to troubleshoot the problem.
