I've had this problem with both my machines.  Also a freind has had this
happen to him also.  In all three cases, the problem was dirty connectors.
All I did to fix it was open up the back of the monitor case (with the
power off, natch) and wiggle, unplug and re-connect every connector I
could find.

It worked for me, maybe it'll work for you.  In any case it don't cost
much to try it.
