Christie maintenance services

1. Protect your investment in Christie products

From preventative projector maintenance to light engine cleaning, Christie maintenance services help optimize the safety, efficiency, brightness and lifetime of your Christie projector. We have the expertise, the tools and a state-of-the-art ISO 6 – Class 1000 cleanroom. We’re here for you!

Did you know? Failing to perform maintenance services can actually void your products’ warranty. And all maintenance services must be performed by Christie accredited service technicians. Please refer to the user manual of your Christie projector for detailed guidelines.

2. Preventative projector maintenance – available for all projectors

We offer 3 levels of preventative maintenance for Christie projectors:

  • Level 1 – Includes a 60-point inspection, cleaning, new air filter, and any needed software upgrades. We also confirm convergence, verify color quality, test all inputs, check audio/video and computer imaging, test focus and zoom, and more.
  • Level 2 – Includes Level 1, plus we remove all covers and any dust from within the projector, clean the light engine, and lamp reflector if applicable.
  • Level 3 – Includes Levels 1 and 2, plus a full optical alignment and correction, including lamp adjustments, boresight, fold mirror and integrator alignments.

3. Bring back brightness with 3DLP projector light engine cleaning

When dust and debris accumulates, your projector loses lumens. A clean light engine can bring back brightness! When you send us your 3DLP® light engine for cleaning, we disassemble, clean and reassemble it, then realign it to maximize light output. It’s only possible at Christie: Using proprietary technology and software, we also align your 3DLP chips and colors for maximum optical output. Your cleaned light engine leaves with a 1-year warranty.

4. Did you know? Even sealed projector light engines benefit from regular cleaning

Sealed light engines reduce the impact of dust and debris on projector optics, which in turn helps extend life. Send us your light engine for sealing. We disassemble, clean and re-assemble it, re-align to maximize light output and then seal it for added protection. Your sealed light engine leaves with a 1-year warranty.

Note: Not all projector light engines can be sealed. Contact Christie Technical Support to find out if yours can.

5. Our promise

During any Christie maintenance service, if we determine that any additional work or parts are required, we’ll contact you, provide a quote and estimated turnaround time, and only proceed with your approval.
