I put a WG 19" in a ms pac cocktail...Interestingly enough, one of the reasons (besides the horrid burn in on the old one) I did so was because of what seemed to be discoloration beyond degaussing fixes...Well, the 'new' monitor also has disoloration in the lower right corner, same spot. Speaker is on the upper right corner so I dont think its that....Maybe the magnet in the cab fan on the bottom? I've used my degausser but no luck getting the color correct...

Also, the monitor is curning a bit on the outer edge all the way up the right side...I've tried with the remote pots to adjust it out but nothing

Ideas on either?
 
maybe get someting like a piece of sheet metal to place/mount near that corner of the monitor and see if it does anything. Could be something in the cab itself as you mention or even something outside the cab in proximity to the cab. As for the curl have you tested this monitor in another game to see if it has curl with all games or just this one? could need to be capped. If this is not the case have you tried every pot on the chassis. Can't remember off hand but when I swapped a monitor into my s pac I had a pretty bad curl. Adjusted all the pots that seemed to make sense with regards ti fixing the issue. Didn't solve the issue. After trying all the pots I eventually solved the issue adjusting something I thought shouldn't effect the monitor in this way. Sorry I don't recall which pot fixed the issue as it was over a year or more since the issue.
 
Thanks!

Well, I figured out the curl...Messed with the H/Vhold on the board...Both were hidded behind the neck.

The color issue is crazy. I put foil over the fan on the bottom of the cab and ALL of the monitor colors went nuts. Deguassed it and now its good except for the same corner...Gotta be the fan I think...Looks 100% perfect when out of the cabinet, close it back up and the discoloration shows up. Something in the cab is doing it...Funny its not an issue for all these cocktails...
 
My cocktail is touchy about discoloration in one corner. If I move the cabinet I have to degauss it. Make sure you degauss it while it is closed. Mine looks great opened but when I close it I have to degauss it again. have you tried turning the game 180 degrees? Is the isolation transformer causing it. Might have to move it. If you think it's the fan, take it out to see if it's better. If so you might have to change the location of the fan or try a different fan
