Nice set.. shame to throw it away... lots of good digital features for an old analog set.

Every channel with a fairly bright image will give a slight "brightness pumping" effect (2-6Hz). If the program image darkens, the pumping effect stops... so it's related to a high-brightness picture.

HV varies around 30-31KV.

Don't have, can't find service manual online, not really interested in spending $40 to get a manual.

HV block has 3 adjustments w/no markings, no way to know if they're all focus or HV adj.

Visual inspection turned up nothing - except dust.

It was doing this when I got it (cheap), about 3 years ago... time to fix it or get rid of it.
