Sounds like a typical comb

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.
