This subject was discussed at considerable length about a year or so ago
on the net, with the consensus being that some significant number of
Commodore monitors have this problem.  I also have one of these, and have
lived with it for almost two years now.  The problem, at least as far as
my monitor is concerned, literally seems to vary with the weather.  Lately,
my monitor has also started causing reboots, something that it never did
before, which has led me to try and seek a solution.

I disassembled the monitor (WARNING -- high voltage inside, even after
unplugging; don't do this unless you know what you are doing), blew all
the dust out of it with compressed air, clipped off all the sharp leads 
on the bottom of the circuit board under the HV section, and liberally
sprayed the HV section with corona dope.  So far, it has not popped again,
but I only did this yesterday and used it for a few hours last night, so
I'm not sure if it is really fixed or not.

Has this problem ever been officially recognized by Commodore and an
official fix and/or monitor replacement policy issued.  If not, since
the problem is obviously a design or manufacturing defect, it seems that
C-A might be leaving themselves open for a class-action lawsuit.
