The optical engine is the heart of the projector, and its failure modes are distinct across technologies. We provide clean-room service for DLP (Digital Light Processing), LCD (Liquid Crystal Display), and LCoS (Liquid Crystal on Silicon) systems.

DLP Diagnostics: The most common catastrophic failure in DLP systems is the "Stuck Pixel" phenomenon, caused by the hinge memory failure of individual micromirrors on the DMD. In Cinema Series 2/3 projectors, a secondary failure involves the degradation of the thermal pad behind the DMD, leading to overheating. We perform certified DMD replacements, ensuring the new chip is thermally coupled correctly. For 3-Chip DLP systems, we also perform 6-axis convergence alignment to prevent colour fringing.

LCoS & SXRD: In simulation environments utilising Sony VPL-GTZ or JVC D-ILA projectors, the primary degradation is often found in the Wire Grid Polarisers. Unlike traditional film polarisers, wire grids are durable but can oxidise, leading to a loss of contrast and a yellow/green haze. We utilise ultrasonic cleaning and replace degraded polarisers to restore deep black levels.

The backbone of any cinema or large-venue projector is its power delivery and logic processing systems. In legacy Xenon systems (e.g., Christie CP2220/4230, Barco DP2K), the High-Voltage Ballast (LPS) is a frequent point of failure. These units must generate a 25kV-30kV ignition pulse to strike the arc, followed by a high-current, low-voltage hold. Unlike generic repair shops, we load-test repaired ballasts to ensure the "Ripple Current" remains within manufacturer tolerances (typically <3%), as excessive ripple causes arc instability (flicker) and premature lamp explosions.

On the logic side, Series 2 Cinema Projectors rely on the ICP (Integrated Cinema Processor) and the Enigma/Formatter boards. A common critical failure is the "Marriage Error" or "Tamper Detection," often triggered by a dying coin-cell battery. We have the capability to repair the underlying board components and, where applicable, re-establish the cryptographic marriage between the IMB and the projector.
