Thanks for the input Chuck, those were the first diodes suspected, no dice.
The set is on now and I'm monitoring cr8712, (8.2v zener), it's stable at
8.17v. The picture is still shifted to the left, no change when poking
around. Gonna scope the video going into the jungle again to see if I missed
something. I've replaced the sub carrier xtal to no avail.
Cheers, Steve
