Go to Radio Shack and get a degaussing coil, ask the sales person how to use it.... it will remove the residual charge left on your picture tube.

The earths magnetic field affects the magnetic deflection in a tv set. This causes your tv to get colour blotches over the screen, but this is corrected by a degaussing circuit, which comes on momentarily at switch on.
If you have hifi speakers in the vacinity of the tele, they could cause your blotching. If you have swiped a magnet over the screen, you may have caused damage.
Here is a possible cure: remove any magnetic fields from near the tv, such as speakers. Turn yout TV off from the Main switch, not the remote. After a minute turn on again.
Most degaussing circuits only come on when the set is turned off from the mains. If the problem is still there (which it could be as you have swiped a magnet over the screen!)
You will need a tv engineer to de-magnetise the screen.

Don't do it man, I got grounded for 2 weeks when I was a kid because I discovered that you can do some pretty neat things with magnets and tv monitors. Well my little experiment ended up costing my parents a couple hundred bucks to replace the TV and costed me a sore ***. I don't know what happens but I know that it isn't good and you'll muck up your tv!
Think of Magnets and TV's like Water and Oil. They don't mix and it is a recipe for disaster. LOL

Big mistake going any where near a tv or pc screen with a magnet, I know because we bought the grand kids a large one from toys are us and they put it too the screen and bingo green and purple figures now come up. My daughter rang a tv engineer and he said it would eventually go but 1 year down the line it hasn't.So sorry you are probably stuck with it.

Picture tubes work by steering an electron beam with magnetic fields. Sometimes a residual magnetic field can get left in the tube and a magnet can reduce it.

With what campbelp2002 said especially with Cathode Ray Tube TVs. I've done it myself and it will slowly resolve on its own as long as you didn't leave the magnet over the screen for too long

The magnetic field bends the path of the electrons so that they don't hit the correct phosphors on the face of the tube.

magnets mess up screens. They mess up computer screens too. I don't know what you can do, try to use a reset to reset the screen... or turn it off and on again.
for the future keep magnets away from your electronics.

magnets will mess the the electronics and the colors of your computer and tv. depending on how long you left it on there it will eventually go away. i did it to my computer when i was little, and it stayed there for like a month.

Try to switch it off completely,like take the plug out for half an hour.
