Optoma GT720 Color Wheel Replacement

Optoma GT720 Color Wheel Replacement – Original 5-Segment RYGWB

If your Optoma GT720 projector shuts down after startup, makes grinding or whining noise, shows rainbow flicker, or displays incorrect colors, the issue is almost always a worn-out color wheel. In most cases, this is the only part you need to replace.

This new original Optoma GT720 color wheel replacement is a direct factory-grade spare part designed to restore proper brightness and color performance. It is not refurbished and not a low-quality replica — built with original glass, mirror coating, and factory balance.

Why Choose This Original Color Wheel

• Factory-spec mirror coating – accurate color reproduction
• Correct RYGWB sequence – ensures proper DLP timing
• Balanced rotor – quiet, vibration-free operation
• New bearing – eliminates whining and grinding noise

Why the RYGWB Sequence Matters

The GT720 uses a 5-segment RYGWB color wheel specifically tuned to its DLP timing. The white segment boosts brightness for short-throw use, while yellow and green improve color visibility in bright environments. Using a different segment configuration (such as 6-segment or RGBRGB) can cause startup failure or permanently incorrect colors.

Common Symptoms of a Failing Color Wheel

• Projector shuts down shortly after startup
• Grinding or high-pitched noise
• Rainbow artifacts or flickering image
• Incorrect or distorted colors

Replacing the worn unit with this Optoma GT720 color wheel replacement restores stable operation, eliminates noise, and brings back original image quality.

Installation is straightforward for technicians or experienced users. The mounting points align perfectly, and the flex cable connects directly.

Don’t replace the entire projector. Replace the one component that actually wears out and get your GT720 back to full performance.

Tip: Compare diameter and segment pattern with your old wheel. Contact us with a photo if unsure.
