Real‑world signs you need to replace the laser module
- Dim image even after cleaning the optical path – the lumen output is significantly lower than when the projector was new.
- Color shift – whites take on a greenish, yellow, or pink tint, and skin colors look unnatural.
- Brightness flicker – the picture pulses in brightness, especially during warm‑up.
- Projector error codes – the status LED flashes a pattern indicating laser/light source failure (often after 15,000‑20,000 hours of use).
- Uneven illumination – one side of the screen is noticeably darker than the other.
If your projector is still mechanically fine but the light source has aged, replacing the H901MCP_R1 gives you another full lifespan at a fraction of the cost of a new projector.
