Recently I had some problems with my SM124; and I wonder if anybody could give
me a hint to fix the bug:

About four weeks ago the monitor started to show some unusual behaviour:
Sometimes a part of the screen went black. As I can remember, only the end of
every Quadword (4 Words!) was breaking down, so I got (vertical) stripes which
were visible and stripes which were invisible. The length of each invisible
part differed from (pixel-) line to line, as well as from one screen-redraw to
the next. Finally last week the whole monitor went black.

While using the monitor of a friend everything was allright, so it must be my
monitor and not the computer.

I think, that it must be a synchronization problem; am I right?
A friend told me, that it may be the result of using a screen saver which
switches the synchronization to external; is he right?

Thanks in advance.
