- Every CTX monitor (and most others) that I've been under the cover of
- have a degaussing coil, but no switch. The degauss is controlled by
- a time/temp device that runs the degauss coil for n seconds when the
- monitor is powered on. Power it down overnight, let it cool, then
- power it on. If the magnetization of the shadow mask is too extreme
- for the built-in degausser, I would suggest that you try a tape deck
- head demagnetizer over the two areas that are affected. You can get
- these at Radio Shack quite reasonably.
