Monitor Problem

Hi there

So i have a common CRT monitor, and i accidentally put a powerful magnet near it. As expected the monitor colors turned pink/green etc. and stayed like that. I degaussed the monitor a few times and turn off and on the PC and it kinda went off. It seems there are still few marks of it, like a really light gray are underneath the center of the screen, although its barely visible. Do you guys know how to remove it?

And also i have the same color problem (just a bit on the right side and on the upper side) with a normal CRT television, not monitor, i am not sure if this happened cause of the magnet too but anyways. Since it has no degauss how do you think i can solve this problem?

Thanks a lot and sorry for being a bit long in the questions but it's really worrying me. Thanks again.
