Sounds like a typical comb filter problem or a trouble with the tuner or tuner control circuit. The only wat to really tell would be with a service manual and a good ociliscope to look at the video and croma waveforms. This is not a repair for the hadi person or the end user. Good Luck and let us know if you got the set fixed.
