Goldstar KN-20V20 Tuning Problem - Need help


Greg Delgado

Jan 1, 1970
In this TV/VCR combo, right after changing channels, picture is
perfect for less than a second then "drifts" slightly out of tune
immediately although picture is still watchable with herringbone lines
and snow. Sound is still ok.

On some channels I see a ghost image of a different channel drifting
from left to right.

33V, 12V, 9V and 5V all appear normal although 5V line is measured to
be 5.85V.

IF output of the tuner goes to a LA7575 IF Processor IC.

Any help would be kindly appreciated.
