NEC CR5450H Color Wheel Replacement – Factory Part (P/N: 102421856, also fits CR5450W)
This NEC CR5450H color wheel (part number 102421856) is a brand new, direct factory replacement built to the same specifications as the original component. It restores your DLP projector’s brightness, color accuracy, and stable operation.
Designed specifically for the CR5450H model, this replacement part also works with the NEC CR5450W. It comes with an NEC Authenticity Verification Barcode Label matching P/N 102421856 – so you know it’s the real thing. Ideal for large venues, rental fleets, and fixed installations.
The wheel uses a Nidec precision motor, spins at 4x speed, and features a 6‑segment RGBCWY layout (Red, Green, Blue, Cyan, White, Yellow). The cyan, white, and yellow segments expand color gamut and boost brightness, while the precision balance cuts down vibration, noise, and flicker.

Why Color Wheels Fail & Common Issues Solved
Dust buildup, long operating hours, and normal wear on the motor bearings are the main reasons a color wheel starts to fail. Typical warning signs include:
- Whining, grinding, or clicking noises from the projector
- Flickering image or colors that look wrong (color distortion)
- Projector shuts down by itself or won’t turn on
- Overall brightness drops or colors look washed out
Swapping the old, worn wheel with this NEC replacement part clears up those issues – you get back stable brightness, accurate color, and quiet operation.
Installation Guide
Color wheel replacement requires opening the optical engine. Unless you have experience with DLP projector repair, professional installation is strongly recommended.
Always handle the wheel by its outer edges. Never touch the colored segments or the glass surface. Use ESD protection (anti‑static wrist strap) during the procedure. A service manual may be available on request, depending on the model.
