Re: CRT Monitor Odd Behavior

With the ageing of the monitor, the power supply regulation and scan
circuit stability has decreased. The most common cause are electrolytic
capacitors going high in ESR. If all the capacitors in the monitor were
to be checked with an ESR meter, there is a possibility of finding many
of them out of specs. This may not be a feasible repair for a monitor as
old as the one that you have.

I've had this Viewsonic PF790 19" CRT monitor for quite a few years now
and
it has been used daily since it was new without any issues. Recently I
have
noticed that large white images will cause the horizontal size to shrink
about 1cm overall. I keep my desktop set to black so if I minimize a
window
I see the picture expand or if I open a window I see the picture shrink.
It
is possible that it has always done this, but I don't believe that it
has.
Any thoughs on what might be going out?
