The unsolvable projector issue: Green/Purple edge shadows



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!
