While rare, it's possible that internal components can cause magnetism issues on the screen.
A CRT can be exposed to enough magnetic interference that the image retains a persistent color or geometry issue. Generally, these issues can be fixed by enough degaussings by the built-in degausser or by using a stronger external degausser coil. While rare, it's possible that internal components or the case shell can cause magnetism issues on the screen.

Internal Magnetic Interference

A CRT can be exposed to enough magnetic interference that the image retains a persistent color or geometry issue. Generally, these issues can be fixed by enough degaussings by the built-in degausser or by using a stronger external degausser coil. While rare, it's possible that internal components or the case shell can cause magnetism issues on the screen.
