Unfortunately the effect was permanent, the built in degausser wouldn't work. I wouldn't recommend fixing it the way we did but it worked. We had to fix it fast to avoid catching heat for ruining that $4000 monitor. We got a big spool of 16 gauge wire and hooked it up to 110 AC USING A HOT PLATE IN SERIES AS A LOAD, to limit the current to less than 10 amps. Holding it close to the screen and slowly pulling it away degaussed the screen and fixed the problem. After about 15 minutes the spool of wire got hot enough to soften the plastic core of the spool. It would be real easy to electricute yourself doing this. You need the screen 'degaussed'. This takes about 5 minutes with the right tools. They should only charge you $10-$20, they don't even have to open the monitor up. Regards, chuck@pierre.mit.edu
