Ok so I was playing Last Blade 2 a little and I notice on a white background there is a black smudge like area on the right hand side of the arcade monitor, what is that?
May be time to invest in a manual degaussing wand.
hmmm, I bought one of these: http://www.uxcell.com/hand-held-crt-picture-tube-degaussing-coil-repair-screen-degausser-p-1454.html is that ok? It's apparently very cheap, but does the job
That should be fine
Any magnetic source would cause discolored areas on the monitor. Speakers that are installed in some cabinets close to the monitor are shielded to prevent this. Try removing the magnet sheet to see if it resolves the problem.Ok so I opened the back of the cabinet (finally) and each side of the cabinet there are what it looks like to be a magnet sheet, could that be causing the problem/ do other people's cabinet have those?
