H818 / H819 Light Route (Optical Path Assembly) – Genuine for Epson CB‑2140W / CB‑2155W
The H818 and H819 light route (optical path assemblies) are designed for Epson business projectors CB‑2140W and CB‑2155W. These two part numbers are fully interchangeable – either H818 or H819 will work as a direct replacement for both models.
When the optical path degrades – even with a new lamp – symptoms include:
- Overall dimness that does not improve with a new lamp
- Uneven brightness or dark patches on the screen
- Blurry image or loss of sharpness
Replacing the faulty optical assembly with this genuine H818 or H819 module restores original brightness, color accuracy, and image clarity. This is a complete, drop‑in assembly – the LCD panels are factory‑aligned on the prism block, so no convergence adjustment is required. Installation is recommended for experienced technicians only.
Before ordering: Confirm your projector model (CB‑2140W or CB‑2155W). If your original assembly is either H818 or H819, this replacement will work. Send us a clear photo of your existing optical block if unsure – we will verify compatibility for you.
