I think the problem maybe in the "video unit pwr" board, or the board the video drum connects too, there are pots on it but adjusting them had no effect. The "video unit pwr" board is cluttered with caps, finding a bad one is going to be a problem for me (don't have an ESR meter)...
So you've been cranking on the pots? I can just guess since I no longer have access to service manuals at my old shop (they are all boxed up and buried in a warehouse now unfortunately and I cannot physically get to them any more ) but pots on the head amp board are probably the luminance and chroma record current adjustments and they will need to be realigned properly.
