This can be caused by a number of things, usually a dry solder joint on the cathode contacts on the small square board connected to the back of the tube.

Other cause can be a malfunctioning transistor which you would find 3 of also on the small square board connected to the back of the tube. these control the (R)red (G)green (B)blue output from the cathode/anode.

Or it could just be that the screen has had a bad knock at some point and damaged the phosphor coating. badly damaged phosphor would not normalise with a degauss.

MY ADVICE: TAKE IT TO THE SHOP![U]
Please be aware that you should not open a CRT monitor and fiddle unless you really know what your doing as they can hold around 25,000volts!!!!
Thanks, you obviously know a bit. I have been thinking about taking it into a shop.. if I can get it fixed for $50 or less, i'll do it. And yeah, thats a lot of power, I wouldn't dare open this thing.
