The Killer Magnet?

Well I was having a good time working on a 600watt sub (bare speaker, no box) and i was hooking up the cables....
and knowing me i has it a lil too close to my monitor and as soon as it got within inchs of it, the screen was sucked in to a 1 x 1 inch display...

lol its kinda funny cause it was and older monitor that was hooked up not my good one!
"whew"

i'll put pics up once i get my digi camera back

You can fix it. It needs to be degaussed. If it has built in degaussing then activate it several times (may take a LOT of times). Some monitors only degausse when you power them up, so you may need to turn it on and off several times.

Also, a soldering gun (not an iron, a gun) or bulk tape eraser can be used as a more powerful degausser. Rotate it in circles 4 - 6 inches in front of the picture tube for a few seconds at a time.

I've fixed some severely magnetized picture tubes with a weller soldering gun.

lol yeah i know its fixable, i'v done it before but i found so funny cause i never noticed and than i put the speakers away and went to sit and play on the computer. But... it was soo small so i had to sit there for a while trying to figure out how it got so small????

Thx, FlyingPenguin

bulk tape eraser? i thoght thoes were system destroyers!! so tahts what they actualy do!

I have one of them (soldering gun)... but never had to use it in that manner.

The trick is moving it in a circle near (but not touching) the picture tube. You want to remove the magnetic field the tube developed.

A real degauser looks like a ring - about 1 foot in diameter, and it's wound with wire:

All you're doing is creating a larger magnetic field nearby the picture tube which strips the magnetic field from it.

Most modern monitors have a built in degauser which is just a metal ring wrapped around the outside front edge of the tube and wrapped in wire.

A soldering gun and bulk eraser are nothing more than big electro magnets and, while not ideal (a degauser ring works better) can be used as a degauser.

A bulk erase does the same thing essentially - strips the magnetic field from a tape.

A soldering gun is basically a big transformer which also - as a side effect - produces a large magnetic field.
