[comp.sys.mac] Mac display white-out

I recently got a SE/30. One day last week, a walked out of my office for
some coffee and while I came back, the screen was different. At first, it
was hard to define exactly how it was different, except that it looked
brighter and was less legible. On closer examination and comparison, the
difference seems to be that it is smearing white dots slightly more
in the horizontal direction. As a result, vertical single pixel wide black
lines appear much less dark than before. 

It is livable, but I prefered it the old way. Three questions for the net:

	* Is this an indication that my Mac display is about to go boom?

	* Does anyone else have any experience with this?

	* Is there any adjustment on the analog board to change this?
	  It doesn't seem to warant the replacement of the entire video
	  board. Also, I would be leery of taking this to a dealer 
	  unless I knew what I wanted adjusted; they would be likely to
	  look at it and say "its not busted". 

  Many thanks to anyone who can supply answers,
