Optoma IS805 Projector Color Wheel – New Original 6 Segment RYMGBC
If your Optoma IS805 projector has started showing strange colors, a rainbow shimmer on fast motion, or makes that high‑pitched whine every time you turn it on — don’t assume the whole unit is dead. In most cases, it’s simply a worn‑out color wheel. This new original IS805 color wheel with 6 segments (RYMGBC) is the exact replacement you need to restore proper image quality.
This is not a refurbished pull from another projector. It’s not a cheap imitation with coatings that delaminate after a few weeks. It comes from the same service channel as factory repair parts — identical glass thickness, same mirror coating, and proper dynamic balance. The IS805 is a well‑regarded home cinema model; this wheel meets Optoma’s original specifications.

Why the IS805 needs this exact RYMGBC 6‑segment wheel
The IS805’s DLP chip and firmware are hard‑timed to a 6‑segment RYMGBC color wheel. The order — Red, Yellow, Magenta, Green, Blue, Cyan — is critical. The magenta and cyan segments extend the color gamut beyond basic RGB, giving you richer skin tones, more vibrant reds, and deeper blues in movies. Drop in a wheel with a different sequence (like RYGCWB or RGBRGB), and the projector may fail its self‑check or produce permanently wrong colors. This original RYMGBC wheel is what Optoma designed — no substitutes work correctly.
Real‑world signs your IS805 color wheel is failing
You don’t need a technician. Listen: a rhythmic grinding or constant whine that changes pitch with brightness — that’s a dying bearing. Look: rainbow trails behind fast motion, or colors that suddenly look washed out, inverted, or just plain wrong (skin tones turn purple, greens look muddy). And if the projector powers on, the lamp lights, but the screen stays dark or it shuts down after a few seconds — the color wheel has failed its self‑test. A fresh original 6‑segment RYMGBC wheel fixes every single one of these issues in one straightforward swap.
Restore your IS805 — not the whole projector
Swapping the color wheel is a doable repair for anyone comfortable opening a projector case. The new wheel mounts exactly to the original screw holes, and the flex cable connector is a perfect match. Once installed, the fresh bearing spins quietly, the factory balance kills vibration, and the mirror coating restores accurate color decoding. Your IS805 will pass its startup check and deliver the clean, colorful image it was known for. Don’t scrap a perfectly good DLP chip and lamp. Replace the one part that actually wears out — and get back to your movies.
