Cry for help
So for some reason my monitor has decided to go a lurid greeny yellow colour with more than a slight resemblence to a fluro combination of both the above. There's something else I could compare it to, but I don't think I will

You know? I mean, I don't really, I'm not a hardware guy. But pixels on your screen are made up of red, green, and blue. The explanation I was given is that there is an electron gun for each colour. The guns sit at the back of the crt and scan across the screen.
Anyway, my monitor had no red. This turned out not to be a major problem, since there wasn't too much pure red in what I was doing (using linux and calling BBSs, as I recall).
A little later (half a year, maybe?), the green gun went as well. Having a monitor that can only display blue was a bit tough.
Anyway, I observed that it was temperature-dependent: on warm days, or days where I put the heater on before turning the monitor on, I might have all my colours. Or, I could run it for a while, and then (once it had warmed up), thump it a few times to get the other colours back.
In the end, the guns were too weak to reach the top and bottom quarters of the screen, so the whole picture was compressed into the middle bit. And it was only blue. That was when we finally decided to get rid of it...
I don't know if this is relevent to your problem; I just felt like telling the story :-)
