My RGB went green!

My Apple II RGB went totally green on me!  Just the night before, 
everything was fine.  I must admit, I've been leaving the computer on 
longer now that I've paid for UltraBlank and it works so well.  At first, 
I thought it might be a harddrive virus with all my downloads.  The 
brightness knob did nothing, the other knobs, very little.  It glowed 
green even with the computer cable detached.

Any ideas?  Is it fixable?  Should I just get a Sony RGB from Alltech for 
$150?  Does anybody want it to tinker with if I can't fix it?
