Nope. That sounds completely normal. It sounds like the degauss function is doing what it should. Degaussing is the act of passing electricity thru a coil of wire around your CRT (Picture tube) for a few seconds as to create a magnetic field that removes any magnetic charges from the CRT. If CRTs were never degaussed, the tube would eventually build up enough of a magnetic charge that it would interfere with the color guns causing mis-convergance (Red, Green, Blue not being aligned properly) and also cause color spots/splotches on your CRT. Degaussing is normal. Most of the time, degaussing takes place when the CRT is cold and therefore you never see this "rainbow" effect. But if the CRT is warm enough to display a picture when it is powered up, you will see the degaussing coil in action for a few seconds. -Steve -- I Didn't Want To Do It, But I Was Sick Of Spam!
