[comp.sys.amiga] 1080 Monitor Burnout

kagle@batcomputer.tn.cornell.edu (Jonathan C. Kagle) (07/14/87)

	Recently, I've noticed that the right side of the screen of my Amiga
1080 monitor (coming up on 2 years old) is yellower than the left side.  I
wrote some short programs to diagnose the problem, and I seem to have iso-
lated it.  When the Amiga displays a screen that is black (000) on the left
side and white (FFF) on the right side with black borders, the white part of
the screen becomes shaded with a burnt-looking brown.  The problem is 
especially noticable when the brightness and contrast controls are turned up.  
Has anyone else had a similar problem?  Is my CRT bad, is the monitor
circuitry dying, or what?

Try de-gausing / de-magnatizing your crt.  Better yet when your amiga is first
booting up and your screen is white, check for uniformity!  If not uniform
try the de-gaussing routine.  If that doesn't work its possible to extend the
life of your tube a little while by finding an HONEST tv shop that has a crt
re-vitilizer.  What it basically does is shock the coating off the guns in the
crt that appear with age.  Some times it works other times no. .... Just a few
ideas.
