Optoma HD803 Color Wheel Replacement – Original 7-Segment 6x Speed (RGBRG+ND+B)
If your Optoma HD803 projector is shutting down after startup, making grinding noise, showing rainbow flicker, or producing incorrect colors, the issue is almost always a worn color wheel. This new original Optoma HD803 color wheel is the exact replacement to restore proper performance.
This is not a refurbished pull or low-quality copy. It features factory glass, original mirror coating, and precision balance – exactly as installed by Optoma. The HD803 uses a 7-segment design with 6x speed (180Hz), delivering smooth motion and minimal rainbow effect.

Why this 7-segment 6x wheel matters
The HD803 is calibrated for a specific RGBRG+ND+B sequence. The ND (neutral density) segment improves black levels and contrast, while 6x speed ensures smooth, flicker-free viewing. Using an incorrect wheel will cause startup errors or inaccurate colors.
Signs your color wheel is failing
- Projector shuts down after power-on
- Grinding or high-pitched noise
- Flickering image or rainbow artifacts
- Incorrect or washed-out colors
Installation takes about 20 minutes. The mounting points align perfectly, the flex cable connects directly, and the new bearing eliminates noise. Replace the worn wheel instead of the whole projector and restore original image quality.
Tip: Verify segment pattern and size before ordering. Contact us with a photo if unsure.
