My grandchildren were playing with magnets near the pc & the screen turned different colors. Is this permanent
Answers:
No, if it's a CRT monitor (cathode ray tube - not a flat screen) you'll probably find an option on the front panel controls called "de-gauss" select it and the screen will shake and -hopefully- restore itself.
If there is no such option, turn the screen off and then on again and repeat every couple of minutes until it looks normal.
The last-resort method is to use the same magnet on the opposite side of the screen to coax it back into position.
Unfortunately yes, and you're going to need a new screen.
It is only permenant if the magnets stay on there for long periods of time.
If it does your monitor may have a built in deguassing feature in it (consult the manual) that will help reset the monitor to a state before then.
As long as the colors are still not there your ok but degause just in case.
Turn it off and turn it back on
Sorry that happened, it is permanent. :( NO magnets on any screen from now on k?
Unfortunately, yes. The magnetics have damaged the color components within the monitor, which is why you get rainbow like circles or line. There is no repair for the damage. Replacing the parts would cost as much or more then a new monitor.
(Sorry)
Yes, and I'm sorry to hear that.
Though there may still be hope. Try degaussing your monitor.
Good luck, and sorry about the monitor :(
It depends. It will probably fade in a day or two. If a semi-permanent field has been induced in the mask, then it need degaussing.
I don't know where you would find a degaussing coil or degaussing service these days. LCD panels don't have this problem, so its becoming obsolete.
Don't listen to the doomsayers. All that has happened is that the magnets have magnetised the metal colour mask behind the screen a tiny bit, which is deflecting the electron beam a bit. The mask is metal and doesn't form a permament magnet. Many screens have a degausser built in that is activated at switch on (the short boinnngggg sound you hear when you turn it on). So usually, such magnetic fields fad in a few days or sooner.
i was playing with magnets near the tv once when i was a kid and this big blotch came up on the screen, and i freaked out. but somehow my brother knew what to do. you know how magnets have two poles, like one side attracts and the other repels? just put the opposite side of the magnet that was used first up to the screen and it will get rid of the blotch. it should work in an instant like it did on my tv.
It is only permanent depending on the strength of the magnet, and how long it was left there. The same thing happened to my TV, but within a few days it was back to normal. Just wait to see if it stays there for more than a week. If it does, its permanent.
No, it's perfectly normal. Try turning it off and on. If not, use the degausser. It's usually in the menu for the monitor. This triggers a magnet that resets the charges, so the picture will shake for a moment, click, and go back to normal.
Insanity is hereditary
You get it from your grandchildren
But seriously as to your problem.
As long as the magnets not very strong, e.g. refrigerator door magnets, the effect should be reversible

As others have said, use the degauss button, or turn the monitor on to activate the degauss circuit.
If it does not clear it in one hit keep trying. However, the degauss circuits typically need to cool down between hits, so leave the monitor for about 20 minutes between degauss cycles.
If that does not look like it is working, then take it to a TV repair shop. They will have a much more powerful degauss wand or ring that they can wave over the screen and fix the problem.
Then you just need to hide all the magnets!
