Need a little help on my winter project. I am building a M.A.M.E. (Multiple Arcade Machine Emulator) machine and this past weekend I finally assembled all of the pieces into my cabinet (email me at email@example.com for pictures if you would like, don't have anywhere to post it online). What I have done is taken a used 21 inch computer monitor, removed the plastic case, and mounted it into the existimg arcade monitor mounts, it was near a perfect fit! Exen thought I have removed the plastic case, there is still a smaller, metal shell around all of the interior guts. This is a good thing, keeps me from shocking and potentially *killing* myself. The exisiting monitor mount was a metal frame. I tested the monitor at the angle it would sit in the cabinet before assemblt just to make sure there would be no problems with the angle. It is pretty sharp, I would say between 60-75 degrees, on its back that it is sitting. Picture an arcade cabinet that you would stand over and look down into for the monitor. When I put it together and fired it up, I noticed color disortion at the corners of the monitor, just like you would see if you placed an unshielded speaker too close to a TV or monitor. My guess is that over its 20 years (the cabinet is dated 1981) the metal monitor mount must have picked up some sort of magnetic charge. So my question is what can I do to exliminate this. Is there a way to "demagnetize" the monitor mount, or should I build a sheet metal "shield" to put between the monitor mount and the monitor. If so, what type of metal should I use. Looking forward to any ideas you may have.
