MAN HOW DUMB AM I >:(
the monitor was on while i was working on it..that what happend before too..i was working while the thing was on...it was for someone else..i was trying to help a really dumb friend of mine...
i know i am bothering you so much mamefan..but please help...
if i buy that disgussing coil..will that fix this?
i do see the black wraping thing around the monitor..what i do with that..please explain it little clear..i am not very good with monitors so i did not understand what you tried to explain...also if i try the magnet,is there any chance i make it even worse?after all..i do not wanna make it even worse while i try to fix it...PLEASE POST...much thanks in advance..this is why this board kick serious --I'm attempting to get by the auto-censor and should be beaten after I re-read the rules--..i did not ever think about what i did(working while monitor on)..anyways..thanks again.

Actually, it didn't matter if the tube was on or not when you used the drill by it. It magnetizes it either way. (When it's on, you just have the ability to see the effects immediately)
The degaussing coil around your tube is there and works automatically every time you turn on your monitor from a "cold" start. (e.g. like after it's been off at least 5-20 minutes, depending on design). That's why most computer monitors, when first turned on give a lound "thunk" sound and the screen wavers a bit. That's the monitor sending 120 volts thru that coil to help remove any magenetism that built up on the metal mask. (side note: This gets built up normally just because of the earth having magnetic poles. However this is a minor amount and not like what you did by putting a large amount of magnetism towards one side of it)
My FIRST suggestion is to simply turn on the monitor, then turn it off, let it sit off a good amount of time to cool down the circuitry that activates the degauss, then turning it on again. Basically turn it on, then off for 15-20 minutes (or longer, depending on monitor), then back on. Do this for a day or so. See if it makes the color/bending less in that corner.
(You see, it works by sending a ton of volts through the coin when first turned on, which, in turn increases heat in a resistor. This resistor shuts down after a few seconds, but must cool completely, and be activated again when it turns on the next time. Without this circuitry, it would constantly be degaussing the screen, causing it to wave and change colors while you used it (and heating up the coil like a light bulb and burning up besides! :( ))
If this doesn't work (assuming the circuitry is working), then your next step is to get a separate degaussing coil or find someone (or buy) a Bulk Tape Eraser like from RadioShack, sometimes you can find them at thrift stores too for a few $, I know one near me had one a few weeks ago for $5.
Follow my instructions in the previous reply on how to use an external degauss coil or tape eraser. You might want to also check out Bob Robert's instruction pages (www.therealbobroberts.com) and click on "you need help" link at the bottom. I think he talks about how to manually degauss things.
Finally if all that fails, try the magnet trick. Start first with something small, like a small poster magnet or fridge magnet instead of the massive speaker magnet. Then you cant ruin it too much, but it might not remove it all. Yes, you CAN screw it up so bad you might not get it out... However, I've gotten some bad bending/color problems fixed by using a broken sliver from a ring shaped speaker magnet (about 1/6 th of it's size) on a 19" arcade monitor a couple times. If you go too far in one direction (e.g. turning purple to green), simply flip the magnet over to use the other "pole" and then undo it the other way.
Good luck.

well you wanted to know what the monitor was..its 19" eygo..i just finished my cab and there is this new problem :'(..i will post about how it turned out..i tried with magnet..nothing but i did make some other spot little darker..the color are okay i think but the spot i was talking about has like a missing color of some sort..i will email you with how its going...thanks for the help ;)

MAMEFAN,
if you are reading..i did try the magnet thing..it made it worse...so what i happend was that the black wraping around the monitor just not in place..somehow it moved by itself...now i just wanted to know if i can just move those black cord and just use duck tape or something to put it back in place..if you are reading...please post..or if you have AIM,ICQ,yahoo messenger...please let me know..i am very sad with the monitor overhere..thanks a lot man.. :D

sNnnakE,
You should put the deguassing coil back into it's proper position. Duct tape should hold it in place just fine. You shouldn't be using a magnet unless you know what you are doing. It sounds like you kinda screwed up your monitor because you don't know how to deguass with a magnet, but if your degaussing coil is put back where it should be, everything should work out eventually after enough cold starts.
