Ok, got a sams as it was easier than digging for the moto manuals in the back room.
I know we eliminated the "H" panel but did we check or sub the "E" panel? that's where the Vertical sync comes from. Might be a crapped out cap causing problems on that board.
As far as the resistor, I don't see it on this chassis and may have been thinking of the Quasar II "hybrid" chassis instead.
So check that panel, there are two 4.7uf caps in the feedback circuit that I am sure are dried up. Also check or replace a 1.5uf on the emitter of the vertical shaping transistor.
Just to be safe, (they are probably on their way out anyway)replace instead of checking C18E, C19E and C28E and let me know what happens.
