I have set this aside temporarily in the hold area,but I remember I did see faint video.Although on the cable from the main board to CRT board I scoped almost nothing on any pins.The high voltage and 1 volt drop on those 2 watt CRT resistors indicate the CRT is barley being driven. I suspect a jungle chip, but the orig. are about $23.00. Ane it's a 19" set... maybe a "junk" set will yeild one.
