I've fixed this problem on my mono monitor more than one. It is
a power supply filter cap that goes south. It a long way from the
regulator chip (other side of the board), but it's easy to see that
it's gone. Just open up the monitor and go looking for a blown cap.
I mean really blown. It takes a 2.2 micro farad to replace it.
