short answers
laptop screen - no, not at all - impossible
desktop (CRT) ruin? discolor, yes.
and permanently. (unless you have a degaussing coil)
hard disk....if it touches the platters ya, but not outside the casing unless it's a supermagnet.
ps, ignore Xeon's paste, it's from a website and has no relevance.
I challenge anyone to prove me wrong

One, magnetic field strength falls off roughly with the cube of the distance. That's an approximation, but it's a useful one, and it means that the one Tesla field from a NIB magnet the size of a marble isn't nearly that powerful 30 centimetres away. Which is why the monitor is not permanently paisley.
The other thing that it helps to know is that magnetic fields and magnetic storage media do mix, as long as the field isn't really amazingly strong.
The field has to be really strong, because it has to exceed the coercivity of the magnetic coating on the storage device. Hard drive platters have a coercivity of a few thousand Oersteds, which means a field of the same number of Gauss is needed to demagnetise them. The ferrite magnet on a computer's PC speaker, assuming it's not shielded, will have a surface field strength of only about a thousand Gauss, so it won't endanger hard drive data even if the drive's right next to it. Even 10,000 Gauss rare earth magnets can't wipe a hard drive if they're not sitting on top of it.

The magnet will probably wipe the hard drive but I don't know if it will do anything to a LCD screen. Just don't take any chances.

Yeah. I've done that before and the green color was always there because of the magnet.

a magnet can corrupt the data on a hard drive or stiffy disk

not with LCD screen

if its powerful and you get to close

ABSOLUTELY,DON'T PUT IT NEAR YOUR T.V. EITHER .THE DAMAGE IS IRREPARABLE.

Don't think so...
