Your problem is different than Mike's. All you need to do is degauss the
tube....this can be done by turining it on....letting it sit on for a
little while, then shutting it off for a while. The degaussing coil that
is apart of the monitor will cure it! You do not need to go buy a
degaussing coil unless there is something wrong with your's (or the
degaussing circuit on the monitor).
I am assuming you are seeing "blotches" of different color mixed in with
color you expect....
