The unsolvable projector issue: Green/Purple edge shadows

Hello,

 

I've been having an incredibly difficult time getting to the bottom of a projector issue.

 

One of the projectors in my classroom (Canon WUX5800Z, with Ultra Short lens) has a discoloration on the edges of objects. For instance, black text on a white background appears normal but with a thin upper edge/shadow above the black that is purple and a lower one that is yellow.

 

I've tried adjusting sharpness, gamma, and focus, but to no avail. The item is almost brand new (<1 yr) and only one of the two projectors is experiencing the issue.

 

Any thoughts on what additional troubleshooting could be done?

 

Thank you!
