     One possible solution that I have been wittness to
is replacing the VIC-II chip with the latest revision, rev.
EIGHT (8). This latest version has by far the 
best video quality of any of the revisions I've seen.
Check with a local service rep or contact 
Commodore directly to obtain the needed device.
(Please verify that the present device is rev 7 or less.)
