[comp.sys.atari.st] Monochrome Monitor Problem

os9paul@gkcl.ists.ca (Paul Good) (03/13/91)

I recently purchased a 'previously owned' SM124 monochrome monitor.  It seems
to work quite nicely except for one minor problem.  When the display is a
black background and there is very little text on the screen, the image is
quite dim.  As more characters are displayed the image brightens as if the
brightness control were being turned up.

Any comments or suggestions about possible components to check/replace?  The
monitor is from Korea and is dated December 1987.

My SM124, purchased new, has always done this. Since I prefer a white 
background, I haven't tried to figure it out.
