Mitsubishi VS-60603 Red Color Problem

[60603Viewer]

My Rear Projection Mitsubishi Model VS-60603 has lost its red color. Everthing else works just fine, just no red color. Is it likely a CRT or some other component problem? What is the least expensive way to troubleshoot?

Make the projector display solid red, green, then blue. You can do this through a computer connected to the projector. If the red is off, then you know there's something wrong with the projector.
