Im getting a lot of discoloration of my 29" med res monitor... im not sure of the exact model number (didnt write it down) but it is a Kortek..
Im guessing its magnetic or something cause of the speakers i have mounted?! I bought a 2.1 system (had everything done to the cabinet at once... so not sure if speakers caused this) and im assuming its not shielded... Is there a trick or method i can do to fix this?
Thanks

well.. been reading up on this.. and will try some degaussing stuff and see how that goes

I have the same issue with my WG D9800. There's a small spot in the upper right corner which is darkened. OSD degauss doesn't do it, but I will try getting a degaussing wand and see if it takes care of the problem. I'll keep you posted. ;)

First, make sure your monitor is in it's final location before you do any adjustments. Large monitors (25" and larger) are extra sensitive to EM fields. Even turning them 90 degrees may show changes in color spots. Some monitors are more susceptible than others.
Once your machine is in it's final location (for a while anyway).... do a couple of cold power up cycles to make sure the degauss circuit has run.
Then, go to Home Depot and get some thin refrigerator magnets.... start with the weakest ones. Cut them in 2" strips and you can move them around the back of the tube against the glass. Once you find the right location where the spot is corrected.... tape them in place.

I would try degaussing it also by using a real degaussing tool; but since they are expensive (about $35+ship) you can try with a regular soldering gun. They have a transformer inside that produces a strong variable magnetic field. Because the magnetic field is variable, conversely to a permanet magnet, it's less likely that the tube remains magnetized after it's use. You put the gun sideways at about 1 feet from the screen, pull the trigger and start moving it away from the screen in a circular motion and release the trigger. If the magnetization of the tube is not very strong it should take it away.

I just had to cycle the arcade on and off quite a bit of times and it looks nice.
Very happy to make a 29" fit in my Simpsons cabinet... hahah!! YAY!
