I had an IBM PC that developed the identical symptom:  after the
machine was turned on and things had a chance to warm up, the IBM Mono
Monitor would take a sharp drop in intensity from time to time, then
quickly recover.  This problem didn't happen when the machine was new; it
appeared after about 1 and 1/2 years of pretty heavy use.

I experimented by removing the IBM Mono Monitor and replacing it
temporarily with a Princton MAX 12 amber monitor.  The problem
never happened with the Princeton, but started up again as soon
as I reconnected the original IBM Monitor.   Thus, in my case at least,
the problem was with failing parts in an aging monitor.
