Original H838B Polarizer (21.5×16mm) for Epson Projectors
The H838B polarizerV ( Blue ) is a genuine original Epson spare part, measuring 21.5mm × 16mm. It is designed for use in the following Epson laser projection models: CB-X39 FH52 FH06 990U 2042 2142W and 2247U.
Polarizers are critical optical components that control light transmission. When the green polarizer degrades – often due to heat or UV exposure over time – you may experience:
- A persistent green, yellow, or pink color cast
- Overall dimness or uneven brightness
- Loss of contrast and image clarity
- Visible color shifting across the screen
Replacing a faulty polarizer with this genuine H838B restores proper color balance and light transmission. Installation requires disassembly of the optical block and precise alignment – recommended for experienced service technicians only.
Before ordering: Confirm your projector model is in the compatible list above, and verify that your original polarizer measures 21.5×16mm and is marked H838B (or visually identical). If unsure, send us a clear photo – we will verify compatibility for you.
