[YLUG] Balck is Green

[Matthew Gates]

Is it a CRT?  If so it could be caused by your screen having been placed 
near a fairly strong magnet.  This can cause a semi-permanent field to occur 
in some part of the monitor which deflects the electron beam just a little, 
causing dis-colouration. 

There is often an option to "degauss" a screen available from the monitor's 
on screen menu.  Choose this.  It should make a clunky buzz noise and the 
screen will flicker for a few seconds.  With a bit of luck the colours will 
be restored to normal.

If your monitor does not have a degauss option, it is possible to fix (or 
improve) it with a strong magnet which you must waft round the screen to try 
to remove the nasty field which is causing the problem.  However, there is a 
very small chance of success, and a high probability of making things worse.  
You could try taking it to a TV repair shop (if you can find some real old-
school place down a side street).
