Laser Phosphor & RGB Projector Repairs
Christie laser projectors represent the cutting edge of projection technology. Our workshop is equipped for deep component-level repair of both laser phosphor and pure-RGB laser arrays.
Laser & RGB Repair Services
Laser projectors require specialised diagnostic equipment and clean-room handling for optical components. Our workshop maintains both.
Laser Driver Board Repair
Gate driver failures, current sense resistor faults, and TEC module issues. We repair to component level rather than replacing entire driver boards.
Phosphor Wheel Replacement
Contamination, delamination, and sync errors on phosphor wheels. We source genuine Christie parts and perform precise alignment on replacement.
RGB Array Balancing
Individual diode derating causes colour shift. We measure each channel with spectroradiometers and rebalance output for uniform white point.
The RGB Pure-Laser Challenge
RGB pure-laser projectors like the Griffyn and D4K40-RGB represent the pinnacle of projection technology. When they fail, replacement is rarely economical — repair is the intelligent choice.
Diode Array Analysis
Each laser diode bank is individually tested for output power, wavelength drift, and thermal stability. Failed diodes are replaced in matched sets.
Beam Combiner Alignment
X-cube and dichroic combiner alignment is critical. We use precision jigs to restore factory alignment within ±0.01°.
Colour Calibration
Post-repair calibration includes white point (D65), colour gamut (Rec. 2020 / DCI-P3), and multi-projector blend matching.
Laser Models We Service
Comprehensive coverage of Christie laser phosphor and pure-RGB laser platforms.
RGB Pure Laser — Griffyn
Christie Griffyn 4K50-RGB / Griffyn 4K35-RGB / Griffyn 4K25-RGB
Flagship pure-RGB. Diode array imbalance, beam combiner misalignment, and cooling failures are the primary repair drivers.
RGB Pure Laser — D4K & M Series
Christie D4K40-RGB / D4K40-RGB 3D / M 4K25 RGB / M 4K25 RGB JS
Cinema and large-venue pure-RGB. Complex multi-module arrays require careful matching during repair.
Laser Phosphor — Crimson & D20WU
Christie Crimson WU31 / Crimson HD31 / Crimson WU25 / D20WU-HS / D16HD-HS
High-brightness 1DLP laser phosphor. Phosphor wheel sync errors and driver faults are the most common issues.
Laser Phosphor — HS Series
Christie D13WU-HS / DWU2022-HS / DWU1612-HS / 4K10-HS / 4K7-HS / 4K22-HS
Versatile 1DLP platforms for rental and installation. Cooling path blockage and phosphor degradation at high hours.
