This question is starting to earn its place on a Macintosh "most frequently
asked questions" list.  If anybody has exact details about just what the
problem is, I would be more than happy to reply to any and all subsequent
posts, after I got my monitor fixed as well.  This problem is quite annoying,
and seems to occur when my monitor passes some not-very-well-defined
temperature threshold.  Usually, once the monitor warms up beyond this
point, it is fine.  Sometimes, getting beyond the temperature point takes
quite a while, with the monitor being unusable for hours; othertimes, it
takes no more than a few seconds to pass this "threshold".

Just what is the problem here?  What can I tell my dealer?  The problem does
not happen to me unless it has gotten pretty cool overnight, but does not
consistently happen even then.  I know I'd like to get this fixed, as I can
just see the monitor finally failing when I am most in need of it...
