Problem was Q2206/2N3906, near video processor. I used NTE159 and have a great
picture.

When I first saw the problem, I rejuvenated the CRT..emissions were low on red
and blue. Rejuvenation was
successful and emissions look good. Picture brighter, but wrong colors.
Where I should have blue, it is green.
I checked every resistor on the CRT board..some I had to pull, they check fine.
Collect on blue transistor is over 200vdc. The other transistors are
considerable lower.
Does anyone have any idea where I can go from here without a schematic? Is the
problem the video proc. IC?
Thank you,
Jeff
