The eMac was an all-in-one G4-based Mac designed for the education market and released in April 2002. It was the last Mac to use a CRT display and was sold at a low price to schools and other institutions.
The CRT has green and purple blotches on the left side. I think degaussing will solve the problem but I've forgotten how to do it.
Are you sure it's been magnetized though? Have you already ruled out other factors via standard troubleshooting steps?

Yes. The standard startup degauss isn't cutting it.

Try a wand then
The degaussing wand can be used and can be found here
I just did some research and you should be careful with the wand, since its much more powerful than the built in one and it can wipe hard drives...
According to this kb article it automatically degausses on startup, though you may want to try with a wand.
