Magnetized CRT

Hey everybody~

I was curious what everybodys opinion is on this (http://www.woil.ws/fixmonitor/) fix for ruined monitors (when degausing doesnt work). I have never had a magnet next to/on the tv and my speakers are pretty far to the side, along with the subwoofer so I can't see what the deal is, I've even taken away the speakers and sub for a while to see if that did it. Does anyone think this same technique would work on a 27" direct-view crt? My Samsung TXP2764 has given me probs for a while (I've gone through 3 with the same problem and my 4th didnt have any problems until now) by having a slight blue blotch on the lower left, green blotch on lower right side, and purplish blotch on the bottom. It's pretty random when it occurs (except the green splotch is always there but its hardly noticable during non white/red images). When red images come on the lower right side is somewhat faded into an orange color which can be pretty annoying. When i turn the tv off for about 2 minutes I can hear it degause somewhat, and it makes the problems in the lower corner a little better when they get out of hand (randomly gets worse every now and then) but it's not a perm. fix.

I also have a problem on the lower right hand side where when brighter colors come on and there is a darker color ontop of the bright background, there is a red line along its contour. It only occurs in about 2 inches by 2 inches on the lower right hand side but it gets annoying too. Having a tech come out to take a look but I hope I can just get Samsung to give me my money back or send out another... I just hope it doesnt get even more messed up after coming back from the tech working on it.

Thanks for any responses/advice

Something is causing the issue and that cause will need to be found and eliminated. Many times there is some magnetic field that comes from unexpected places. I suggest you get a compass and see if you can find the source of the magnetics. The set should degauss itself. They used to sell degaussing coils for this purpose.

I was thinking a degausing coil might do it too, I'll have to look into that. I've moved the TV around to different areas as well but the problem still occurs. Once the set is somehow magnetized, will the problem stay with it until it's fully degaused, or what?

I used a compass also, and the magnetized area is directly underneath the tv, increasing when going upwards towards the bottom of the TV... only where the problem mostly occurs (if I move the compass to the other side it goes back to pointing in the right direction), but nothing is even under there so could it be the TV itself?

You've only succeeded in finding the power supply... look for EXTERNAL magnetic fields... transformers, motors, electric supply lines... Speaker magnets, of course...

My new Samsung TX-P3075WH had a greenish area in the lower left corner, and I fixed it by unplugging the TV for over thirty seconds, and then plugging it back in. This happened after I was messing around with my 18 year old VHS VCR at the lower left side of the TV, so I am guessing that was the cause.
