I cannot remember the issues Kamakiri had with this set after the recap. But glad I decided to trace that circuit back. I figured looking at the schematic that it sure looked like this circuit was feeding the IF and video sections and since I was having issues with both that it seemed more than likely the issue was there someplace. Set was rock solid after 2 plus hours viewing late last night.
