Epson CB‑L1000U LCD Module Replacement, Compatible with L1100U / L1105U / L1200U Projectors – Complete Block (H733)
Factory pre‑aligned – no convergence adjustment needed. This is a genuine Epson complete LCD assembly (part H733) for CB‑L1000U, L1100U, L1105U and L1200U laser projectors. Unlike single LCD panels, this assembly includes all three LCD panels (red, green, blue) factory‑mounted and pre‑aligned on a single optical base. Installation is purely mechanical. You do not need to adjust focus, convergence, or panel registration. Simply remove the old assembly and install this one.
The assembly is brand new, original Epson spare part. It is factory‑calibrated, so after replacement you get perfect colour alignment right away. This is the correct repair solution for failed polarisers, burnt LCD panels, or optical block damage – without the complexity of individual panel alignment.

Why choose the full H733 LCD assembly for laser Epson projectors
Replacing a single LCD panel on a high‑end Epson 3LCD laser projector requires hours of delicate convergence work. The H733 assembly eliminates that. You swap the whole pre‑aligned block – all three panels are already matched and focused at the factory. This saves significant repair time and guarantees a factory‑correct image. If your projector has colour fade, severe polariser degradation, burnt panels, or optical block damage, this assembly is the correct long‑term fix.
Signs you need this LCD assembly
- Severe colour fade or yellow/brown tint – polarisers or LCD panels have degraded.
- Blank or dark image on one colour channel – one panel or its driver has failed.
- Mura / uneven brightness across the image – blotchy or non‑uniform colour.
- Physical panel damage – burnt spots, cracks, or delamination visible inside the optical block.
- After poor repair attempt – previous misalignment or dust contamination that cannot be cleaned.
Installation guidelines
The H733 assembly is a direct mechanical fit. You will need to open the projector, remove the optical block from the main chassis, and swap the old LCD block for this new one. Dust management is still important (work in a clean environment), but because the assembly is pre‑sealed and factory‑aligned, you do not need to touch individual panel adjustments. The flex cables attach exactly as the original. Service manual steps are not included, but if you can replace an optical block, you can install this assembly.
Important: Work in a low‑dust area. Take clear photos of the original cable routing and screw positions before removal. No test patterns, convergence tools, or service menu calibration are required.
Restore your laser installation projector to factory condition
CB‑L1000U, L1100U, L1105U and L1200U are high‑value laser installation projectors. Replacing the full LCD assembly with a genuine H733 block restores original brightness, colour accuracy and uniformity. It is far cheaper than buying a new projector. This plug‑and‑play optical block keeps your installation running for years.
Note: If you are unsure whether H733 matches your projector, send us a photo of your original LCD assembly or the part number label. We can confirm compatibility before you order.
