Some monitors have a degauss button to manually degauss (demagnetize) the picture tube. Newer monitors generally do this automatically at power-on (that's the "don-n-g" you hear and the shakiness you see when you first power on the monitor). If you open a monitor case (and don't know what you're doing - you'll get knocked across the room when you come in contact with the high voltage circuit), you'll likely see a thick cable running around the circumference of the monitor. This is the built-in degaussing coil. On even older monitors/tvs, you'd need to use an external degaussing coil (although a bulk tape eraser would do in a pinch) and manually move the magnetic field in circles around the monitor as you slowly pull away from it.On Thu, Feb 20, 2003 at 01:21:30PM +0000, Glyn Millington wrote:Have you tried pressing the Degauss button on your monitor?GlynHuh? Speak up, man!
The same type of discoloration can also be caused by external magnetic fields, such as by having a second monitor too close to the first one, or a fan, or over-powered speakers, or etc etc etc..
