See if you can isolate the problem to the computer or the monitor.  If
it is the monitor, it is very likely to be the flyback transformer,
get it replaced.  If the computer is the culprit, either a transformer
or a coil is the most likely culprit but I couldn't begin to tell you
how to isolate which one :-).
