Projector Colour Wheel Repair: Symptoms, Causes & Solutions

A failing colour wheel is one of the most distinctive projector faults because it produces both visual and audible symptoms.

How Does the Colour Wheel Work?

The colour wheel is a rapidly spinning glass disc coated with dichroic filters that separate white light into red, green, and blue components.

Common Symptoms

Rainbow effect, flickering colours, reduced saturation, and high-pitched whining or grinding noise.
