I know this is the completely wrong section to be writing in, not even the
right site really but microsoft support has always done me well. Someone has
accidently put a 6" speaker to close to the monitor and it has drawn out the
colours of it. it was far worse before but i have sorta moved the colours off
teh screen wtih the magnet far away. the monitor doesnt have a degauss switch
and doesnt clear when turned off, unpluged, or shutdown. Any suggestions or
have poked my monitor for good?
Any help much appriciated
Thanks

Similar problem happened with a television set due to a big speaker that was
put on top of it. Yeah it ruined the color for a bit but after a very very
long time, it went back to normal.
 
My husband is a video game tech, and he uses a ring ( I think it is a
magnet). He circles it around the front of the game monitors about 3 times,
then pulls it straight out, away from the monitor. He also used this on our
TV after it had been sitting too close to the fridge. Don't know where you
might get one of these rings, but you could start with Radio Shack maybe?
 
maybe ill try the magnet that did it lol... thanks heaps for ur replys i will
try that. if it doesnt work ill wade it out the previous text sed it should
come right after time. Thanks heaps

Off topic indeed.

However...

You may be able to find an external degausser. I haven't used one for more
than a decade, but I once borrowed one. It was a largish coil that ran on
mains power, and did a nice job clearing up some trouble with the screens of
an Intergraph workstation. (I was lucky, as I might have gotten into
trouble, as the CRTs were built-in. It would have been wise to keep the AC
magnetic field away from the hard drive and other components.)

I borrowed the degausser from an electronics tech at the lab where I was
employed, but they were supposed to be available at TV repair shops.
(Unfortunately, TV repair shops are vanishing, at least in the USA. It's
often cheaper to replace a TV than to repair it.) If you are sufficiently of
the do-it-yourself type, you can find (Google) instructions on how to build
one on the Web.

Or, just wait a while. The ferrous parts that were magnetized by the
speaker's permanent magnets will probably slowly lose their induced
magnetism. The monitor probably also has a built-in degaussing function,
although it may only operate when power is applied. (Also: does the monitor
have a degauss function that is accessed through an onscreen settings menu?
The last two monitors I've had at home were made by Sony, and the degauss
function was only available through the settings menu. There was no discrete
button for it.)

Address scrambled. Replace nkbob with bobkn.

Most modern CRT monitors have a built-in degausser. If it isn't a separate monitor
function, its built into the power on function.

The objective would be to turn off then turn on the monitor. Wait 5 secs, turn off then
turn on the monitor. And cycle that a few times or so until the the colour blotch goes
away.
 
Yup, I had the same thing happen. If my speakers are 11" from the TV, the
color gets wacky. Red gets dragged across the screen. A foot away and it's
fine. TVs and monitors demagnetize themselves each time they are turned on.
The problem goes away, unless the magnet near them does too much damage.
 
Hey thanks heaps guys it just popped right. Thanks for so many posts! i got
about 9 in a few hours thats heaps of support thanks heaps ppl. I cleared all
the colours off as best as i could with a smaller magnet, jst dragging them
off th screen. then turned it off and back on and it poped right. For anybody
else that is dumb enuf to get a speaker close to a screen :)
THanks heaps guys

I mentioned the power cycle degauss, but I thought that it would be
preferable to do it manually rather than power cycling the monitor multiple
times.

I should have warned that some monitor makers recommend waiting between
manual degaussings. I'm not sure, but it may be a thermal issue.

As the OP managed to solve his problem by waving around a permanent magnet
plus a power cycle or two, I guess it no longer matters.

FWIW There is a BIG difference between "shielded" and non-shielded
speakers when it comes to monitor distortion effects.
