Why RGBCWY & 5x Speed Matter
The EX728EST uses RGBCWY timing for short‑throw education and business. White segment boosts brightness in well‑lit rooms; cyan and yellow improve color accuracy. 5x speed sits between standard 4x and high‑end 6x – noticeably smoother than 4x with less rainbow effect, yet easier on motor longevity than 6x. Wrong wheel causes startup failure or wrong colors.
Signs Your Color Wheel Is Failing
- Projector shuts down seconds after lamp lights
- Grinding or high‑pitched noise (worse on bright scenes)
- Flickering image or rainbow artifacts
- Washed‑out colors, yellow/pink whites, or orange reds
Replacement takes about 20 minutes. Mounting holes align perfectly; fresh bearing kills noise, factory balance stops vibration. Don’t scrap the whole projector – swap the one part that wears out and get back to reliable short‑throw performance.
Tip: Match segment pattern (RGBCWY) and diameter with your old wheel. Send a photo if unsure.
