OOPSIE! TV COLOR MESSED UP!

I set my flashlight with the VERY powerful magner inside of it near the TV in out kitchen. Now the bottom left corner's color is funky. Any way to fix it cus the TV is to old and has no degausing functions? I herd it migth fix itself?

Yeah, it needs to be degaused, it might go away on its own, although I'm not sure.

what causes that to happen?

ive done this loads of time on purpose just to look at the colors.

all you have to do is either deguass, or get a maganet, and sort of move the color so that its no longer on the screen. its hard to explain, but basically get a small magnet and try to move the colored area around.

i found that if you unplug the TV for 1 week, it should be gone.

Try this: a degaussing coil.

CRT displays have a metal mask right near the front of the monitor, with a holes (or slits) the size and shape of each pixel.

(i once had the opportunity to look at one of these when i found a smashed CRT monitor. the holes are sooo small man. it looks like a see-through piece of metal)

anyways, when you put a magnet near it, it may become magnetized itself. the electrons that are being aimed through the holes will deflect in the presence of this magnetic field, and electrons intended for one colour pixel may hit another colour one, or just the mask itself.

I learn a ton more here than at school.

I did that with my TV. It just fixed itself over a period of an hour (being on the first half hour and being off the second.).

@Vskid: As do I.

The TV isent used often mabe on for 2-3 hours a day so leaving it off wont fix it.

Degausing coild is to expensave as I am a cheepscate!

I believe I once saw a diy degause gun on g4tv.com. It worked like this. You had two magnets (I believe) and they straped them on a drill. Get them near your screen (while it's on) and start spining. it looks cool and degauses your screen.

If it's a fairly small TV you could try waving a metal bar with a bunch of magnets on it around the screen.

If you have another TV that's a similar size which does degauss itself, you could try this. Face them glass-to-glass on the floor as close as possible, turn the bad one on, then turn the good one on. The good one should degauss itself when it turns on, and it might have some effect on the bad TV.

Or you could try that trick but with a CRT computer screen. At school we have a couple old ones that are strong enough to degauss any other CRTs within a couple feet away.

If all else fails you can try looking up a repair place in the phone book.

Only thing I have that can degaus is a computer monitor...

Set it close to the bad tv, and degauss. it should work.

I went and samshed a screen just to look and the are small! reallly small!

thanks for the description, very concise
