Epson Projector Repair
Epson is the world's leading 3LCD projector manufacturer, producing the most natural colours in the industry. The optical engine is complex: three LCD panels must be aligned to within a micron. We are the UK's leading Epson 3LCD specialists with factory-grade convergence tools.

Common Epson Faults & Fixes
Our technicians regularly resolve these Epson 3LCD-specific issues.
Discolouration — Yellow or Pink Tint
The image develops a yellow or pink tint. The organic polarising plates in the optical engine have degraded due to heat and UV exposure. We rebuild the optical engine with new inorganic polarisers to restore perfect white balance and brightness uniformity.
Overheating (Temp LED Flashing)
The temperature LED flashes red and the unit shuts down. While often caused by blocked filters, it can also indicate a failed thermal sensor on the LCD panel. We clean all airways and test or replace thermal protection circuits.
Lamp Ignition Failure
The projector attempts to start but the lamp never strikes. This is usually a failed ballast (high-voltage power supply). We test the ballast under load and replace it if the output voltage is below specification.
Auto-Iris Motor Failure
The auto-iris mechanism in home cinema models (EH-TW9400, EH-LS12000B) sticks or produces clicking noises. This reduces dynamic contrast. We disassemble the iris, clean the mechanism, and replace the stepper motor if necessary.
LCD Panel Degradation
Individual LCD panels age at different rates, causing colour non-uniformity across the image. Visible as green/magenta tints in corners or vertical banding. We recalibrate convergence to factory spec or replace degraded panels.
Lens Shift Mechanism Jamming
The motorised lens shift in EH-TW and EH-LS series stops responding or drifts from stored positions. We service the lens assembly drive mechanism and recalibrate the position sensors.
Epson 3LCD Technology Explained
Understanding how 3LCD works helps you identify issues early and make informed repair decisions.
How 3LCD Works
White light is split into red, green, and blue. Each colour passes through a dedicated LCD panel, then recombined via a prism. This produces natural colours with no rainbow effect.
Why It Degrades
Organic polarisers degrade under heat and UV. Dust settles on panel faces causing "dust blobs." Thermal cycling loosens prism alignment causing convergence drift.
Our Repair Approach
Clean-room optical block disassembly. Replace polarisers with inorganic equivalents. Precision convergence alignment to sub-pixel accuracy. Full brightness and colour calibration.
Epson Repair Value
Epson projectors are built to last. A professional repair is highly cost-effective compared to replacement.
