I have an IBM "Enhanced Color Display" EGA monitor, type 5154.  It has a
hardware failure.  When I last investigated getting it repaired, all
avenues seemed to lead to a fixed fee of ~$370.  I am seeking advice
about whether to trash it, try fixing it myself, or pay.

Symptoms:

1. When first turned on, the background brightness is unusually high and
   the vertical height is too.  Both recover to normal during 5-10 minutes
   of warm-up.

2. Failure takes one or both of two forms, both after some warm-up:

   (a) The raster splits near the center of the picture, creating a
   mostly blank horizontal stripe across the center.

   (b) A generalized raster degradation takes place in which the
   characters are just recognizable but poorly formed.

   There is an accompanying smell, like of an electrically overheated 
   component.
