Recently, my venerable P1110 has gotten "jumpy". The screen will begin
to get pincushion and "twitches" between a good display and the
distorted one. The distortion gets more severe and more frequent until
the deflection totally collapses and the monitor suddenly shuts off,
restarts, and goes back to the same thing. Or not. Sometimes the
twitching is incessant, sometimes it's not a problem for a few hours.

Because convergence and focus are fine during the "seizures", I suspect
a power supply problem in the deflection drivers.

Any suggestions or info on known problems? (This is the same model that
has a tendency to drift to higher and higher brightness -- I've already
dealt with that one).
