Or you had a really strong magnet…
Comment on Are modern electronic devices (i.e. cell phones) still susceptible to damage from magnets?

A magnet on a old CRT TV would distort the colors and image in cool ways along the magnetic field. Nothing permanent unless you left it there for a long ass time. Ahh memories…

A magnet can absolutely fuck up a color CRT beyond repair by causing an extreme misalignment of the shadow mask or aperture grille that even a degaussing wand can’t fix.
Black and white CRTs are fine, though.

A strong one would fuck it up ‘permanently’, as in it took active measures to restore a good picture (degaussing).

Had an audiophile buddy who had two giant speakers next to his CRT TV.
There were two permanent half circles on either side of the TV. It was bad enough that degaussing didn’t help.
He didn’t care one bit about video performance, just wanted his audio to be the best he could.

I got permanent damage on a CRT by playing with some magnets neat it. Never left them around it overnight or anything. They were the magnets from the magnetic beyblade arena lol. The sides of the screen got sort of more red. If bright colors, especially white, were on those areas for a long time they’d get progressively more discolored. It would fade back to its mostly normal dull red shade after some time without the bright white. So it wasn’t the worst damage ever, but it was definitely permanent damage and definitely noticeable.
