Our traditional TV has been knackered by our 4-year-old playing "distort the image" with her magnet. Are plasma or LCD TVs any safer?
I don't know if a magnet hurts them, but once they die they can't be fixed.
So I heard anyway a couple weeks back when some people on the radio were talking about HD tv on my sports radio.

• No colour staining
Unlike CRTs, Plasma TVs are immune to magnetic fields,
which means they can be used in close proximity to
hi-fi or surround sound speakers, with no danger of the
picture becoming affected by the magnets inside the
speaker.

I don't know about LCD TVs though.

I think this says that LCD TVs are affected.

When kids get near the set with a magnet, the magnet makes part of the electron aiming mechanism take on a slight magnetic field which ruins the aim of the beams in that vicinity so things change color. But the Degauss coil, which can be an external one you plug in and wave around in front of the screen or internal. Good luck deknackering it!

Originally posted by MixoLCD screens at least, and IFAIK plasma ones as well, don't work by bending a ray of particles using a avrying magnetic field, so yes, they're safer in this regard. OTOH, they're easier to push over, because they're lighter and typically less stable.

I must say, though, that I share your daughter's amusement at what a magnet can do with a CRT. You can make very pretty, colourful patterns that way. Unless it's truly badly banged up, a good repair shop should be able to fix it, by the way, and for small spots you can often do it yourself with a bit (or sometimes a lot) of patience.

Instead of using magnets on LCDs, you just poke it with your finger to get interesting patterns.
