Is the image projected by your projector missing one or more colors? Maybe a whirring noise whenever you switch on the projector. These would be the result of a broken color wheel. Color wheels are responsible for parsing color to the screen where your images are being displayed.
When the color wheel is broken, the projector will be noisy. An outright malfunctioning color wheel will actually prevent the projector from booting since the boot sequence requires a spinning color wheel before the lamp gets energized.
We can replace your color wheel speedily with warranty as well. Call us, our service is nationwide
