Subject: Hitachi SuperScan monitor displays odd "ribbon" across top of
screen
This is my first time posting here, and I hope this is the right place
for
this problem.
An area about 2.5 cm at the top of my Win 98 desktop shows extra
lines --
white, gray, a few black -- just after starting. Icons in this area look
stretched vertically and at the very top of the screen they look "folded
back" on themselves. When I move the mouse pointer to its upward limit,
before it stops it emerges again stretched and heading downward.
The area spans the screen and used to shrink to about 4mm high after ten
minutes or so. Lately I've noticed that it doesn't reduce as much (ie,
problem getting worse?). If I shut the monitor off with Win98 running
and
then turn it on again, they're back.
One odd thing is, the length of each successive line is a bit less than
the
one above it, so the ends of the "band" are angled inward. Also, the
Win98
splash screen doesn't show the lines during boot-up. Weird?
I've been thinking maybe a reinforcing wire on the mask broke? Someone
suggested a "broken sweep generator." I hope it's a software problem and
not
the monitor, but please tell me if you know what it is and what to do.
Please help if you can. Thanks.
Oh, and it's a Hitachi SuperScan Elite 751.

Defective capacitors in the vertical amp section in the monitor are
usually
the normal cause of this. It is possible to have some semiconductor or
other
component failures to cause this, but not very often. If you continue
to
use the monitor this way, there will be more damage, thus increasing the
cost of the repair as usage goes on. Take the monitor to a service
centre
that is authorized to work on computer monitors. This type of repair
should
generally not be too expensive.
After your monitor is properly serviced, it will work normally again.
