Discoloration on Monitor - Sharp Image SI-319S

[RetroJames]

I have a Sharp Image 19" color raster monitor in an omega race cabinet.

Probably needs to be manually degaussed.

I had them unplugged

Unplugging the speakers won't stop the speaker magnet from affecting the monitor colors. If speaker magnetism is suspected of causing color problems you need to actually remove them from the cabinet and get them at least 4 feet away from the monitor. Then manually degauss the picture tube.

As it is an Omega Race cabinet and I mounted the monitor as the original would have been, that is using the reflective mirror arrangement, the speakers are already at the top of the cab while the monitor is at the bottom.

I did use an amp from pc speakers andmounted the internals near the topofthe monitor.  You can see them on the upper left, the small pcb and what might be some magnets?

Also note the switch is for the monitor and I routed the power from the switch to the rear of the monitor across the area above the coindoor which is where the top of the monitor rests when mounted. 

Do you think it is possibly comming from one or more of those sources?

Thanks!

Could be that fluorescent light ballast is too close to the monitor. Try disconnecting that light fixture.

I did turn it off and tested again with same results.  Does the ballast have magnets in it as well?
