How to Degauss


Hello,

LCD flat panel monitors do not have or need a degauss function. The older CRT monitors had the degauss button to remove any magnetism that built up in the metal frame that would cause distortion. LCD monitors do not rely on magnetic fields so no degauss button. If your display is showing strange patterns and text the most likely cause is a bad video card. First try a different monitor on your card. I would bet the display is bad on it too. It you find this problem just replace your video card and the issue should go away.

Degaussing


Degaussing only applies to CRT monitors not LCD. The old CRT monitor could build up a magnetic interference and the degauss would repair this by activating an electro-magnet that was wrapped around the outside of the picture tube. You have probably created a "burse" on your screen, the only choice is to replace the screen.

Hope this was of some help

When i turn on my tv, the screen has like rainbow color all over it. i found out if you hold a magnet up to the screen, the color moves if you move the magnet. no picture of anything,,just color i...


To fix this, you need to do something called degaussing. You should keep magnets away from the screen in the future, because they cause this problem.
The first thing to try is to turn it on and off, making sure that all magnets and speakers (which have magnets in them) are kept far away from it. This will activate the monitor's auto-degausser if it has one. If this does not help, this guide: http://www.wikihow.com/Degauss-a-Computer-Monitor gives a couple solutions, including using a soldering gun (not a soldering iron), illustrated in the video below:
With a powerdrill:

Or investing about 60 bucks in a degaussing coil like this which is a guaranteed fix:
One other trick that might work is to take an old CRT monitor ("fat-screen" rather than "flat-screen"), hold it up to the tv screen to screen, and turn it on and off to have the monitor use its own degausser. The monitor may have a button to activate degaussing, or it may be in the menu you can bring up with the buttons on the bottom of the screen.
If you don't want to deal with any of this, a tv repair shop will degauss your tv for you quickly.

Where is degausses key on my monitor"


LCD monitors don't have degauss buttons. Degaussing was needed with CRT monitors because a magnetic charge would build up on the screen and need to be reset occasionally, though in later CRTs this was done automatically whenever you turned the monitor on.

Color is all messed up and the reset button will not reset.. what do we do to fix it?


Describe the problem more clearly (color blotches purple and green?) But it sounds like the set is probably magnetized and needs degaussing (demagnetizing).
All CRT type TV's have an internal demagnetizing circuit that is engaged when the set is first turned on after being off for the day.
If this circuit is working then you sometimes hear a "bonk" sound (about 1/2 a second long when the set is first turned on. If this circuit isn't working the set will become magnetized over time and will have to be degaussed using a degauss coil available at a TV repair shop (cost aprox. $35.00) and you should have the circuit checked at the same time. A set will also become magnetized if a large speaker (magnet) or motor is close to the TV. Be sure to vote/rate me if this helped Thanks!

Permanent dots and lines have been developed at the right corner of the monitor how can i remove them


Try this; it may help. There are some buttons in front of the monitor. Hit the "menu" button. See if you have a "degauss" option. Select the "degauss". If the monitor has stayed close to a magnetic source, it will be effected by the magnetic (try to put a magnet close to the screen and you will see what I am talking about). The "degauss" will take care of the problem.

Or you may simply have a bad monitor. Good luck.

Picture on monitor is distorted


I went to the panel buttons, and then punched the reset for each of the icons on the menu. That restored the display picture to its factory settings. The degaussing did not help the picture, and any stray magnetism is generally automatically degaussed when the computer starts up. As to the flickering of the picture, that is because of the refresh rate. I am using a relatively updated operating system, and the refresh rate has changed somewhat. I also believe the temperature of the computer affects the flickering. I hope this comment helps someone who has a similar problem.

Best regards,

Monitor colour change


The discoloration problem is due to the near by magnetic field (magnetic interference or due to magnets) appliances like speakers which are very near to monitors ...
so what you have to do is just keep some distance to the monitor from the speakers and other magnetic appliances and then press menu button & just give degauss..

Degaussing a NEC LCD1700M+


LCD type monitors don't use a degaussing coil. Older CRT type monitors used/needed a degaussing coil built around CRT for de-magnetizing.
