Magnets on CRT Screens
Date: Around 1999
Someone put a large horseshoe magnet on several computer
screens and screwed up the picture how do I revert the screens back to
normal. I've seen it done in an old physics class but have since forgotten.
The monitors need to be "de-gaussed". Some monitors have a button that runs
AC through an internal coil that does this automatically. Otherwise, I
think it can be done with an external coil; however, I don't recommend
trying it until you know "exactly what and how". Contact a local TV repair
shop, they will be able to tell you "exactly what and how" to do this.
