BenQ Th671st projector color wheel Replacement

BenQ TH671ST Color Wheel Replacement – Original Label 102426843

So your BenQ TH671ST projector is acting up. Maybe it shuts down a few seconds after the lamp lights. Maybe it makes a grinding or whining noise that gets louder with bright scenes. Or maybe the colors look wrong – skin tones appear muddy, whites have a yellow tint, or you see constant rainbow flashes. Before you throw it out, know this: that’s almost always the color wheel.

This is the genuine BenQ TH671ST color wheel, factory fresh with authentic label 102426843. Not a refurbished pull from some other dead projector. Not a cheap copy with unbalanced motors or coatings that peel off after 50 hours. Exact match to the original: 6 segments, 6x speed, RGBWCY sequence (Red, Green, Blue, White, Cyan, Yellow).

Why the RGBWCY sequence and 6x speed matter

BenQ’s DLP timing on the TH671ST is specifically calibrated for the RGBWCY color wheel sequence (Red, Green, Blue, White, Cyan, Yellow). The white segment boosts brightness for gaming and well‑lit rooms, while the cyan and yellow segments improve color saturation and skin tone accuracy. This combination makes the TH671ST ideal for short‑throw gaming and home entertainment. The 6x rotation speed virtually eliminates the rainbow effect, providing a smooth, flicker‑free image. Using a different wheel (such as RGBRGB or RYGCWB) can cause startup failure, washed-out colors, or permanently incorrect white balance.

Common symptoms of a failing BenQ TH671ST color wheel

• Projector shuts down shortly after power‑on (often with a loud whine)
• Grinding or high‑pitched spinning noise
• Rainbow artifacts or flickering image
• Colors look dull, whites have a yellow/pink cast, or reds appear orange

Replacing the old unit with this genuine BenQ TH671ST color wheel (label 102426843) restores proper operation, eliminates noise, and brings back accurate, bright colors – perfect for gaming, movies, and short‑throw projection.

Swapping the color wheel takes about 20 minutes if you’re comfortable opening a projector. The mounting holes align perfectly, and the flex cable connects directly. Once installed, the fresh bearing eliminates noise, and the factory balance ensures smooth, stable operation.

Don’t scrap a good DLP chip and lamp. Replace the one part that actually wears out — and get back to rainbow‑free, vibrant projection in no time.

Tip: Verify the label number 102426843 on your old wheel. Match the segment pattern (RGBWCY) and diameter. Contact us with a photo if unsure.
