I'd first suspect an HV arc/corona issue....I've seen that type of issue on electromagnetic deflection sets when the HV is arcing.

Micas most often go bad in the deflection section (where they take the most abuse), so they should be on the list under the "after everything else tests good or has been replaced in the ____sweep circuits if problems remain change the ____" heading. Never change RF/IF stage micas without first PROVING they are bad.
