It's probably something up with the input (voltage fluctuation
maybe?), or the coils (yoke?). CRTs work on the principle of electron
deflection and the coils (yoke?) around the monitor push electrons
(fired by the electron gun) towards parts of the screen on a per-pixel
level. They scan in some kind of pattern doing that if I recall. So,
if the input is higher or lower than it should be the electrons will
get pushed farther in whatever the direction of movement than they
should (even off the screen). That is, more voltage is being applied
to the coil than you want is what I think. The question is why.  I'm
going to assume that this could be a  capacitor problem or some kind
of issue with the input signal generation. So it would seem likely to
be either the power supply or the analog board (the bit with the
monitor controlling pieces).
