That clears it up. I was wondering if CRT coolant was low or leaking but
perhaps not. Try replacing C4503 and see if that makes any difference
(affecting delection of the beam within the CRTs. I also assume that it does
this on all three CRTs which would lead me to suspect a deflection related
problem.
