Common Griffyn 4K35-RGB errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.
- Step-by-step fixGet the fix →
Coolant/pump errors then lasers shut off: "Coolant Low Flow", "Impeded Flow", "Liquid Cooling Pump High RPM", or "Light Engine Overheating"
Likely cause: The RGB laser bank thermally throttles or trips off when coolant flow/pressure drops.
- Step-by-step fixGet the fix →
Focus drifts / image softens when content changes with the ultra-short-throw lens
Likely cause: Thermal expansion in the UST optic shifts focus with sustained light-level changes; Christie documents this as a known characteristic of that specific lens rather than a fault.
- Step-by-step fixGet the fix →
How to update firmware / what version to run
Likely cause: Griffyn runs the shared Christie TruLife+ firmware; staying current fixes known bugs and adds features, but exact build numbers are gated behind Christie support.
- Step-by-step fixGet the fix →
No image / source not displaying
Likely cause: Standard image processing is 24–60 Hz; anything above that is gated behind the Mirage option, so a "no image" at high refresh is often a licensing/mode issue rather than a cable fault.

Projector dims or throttles in a warm room
Likely cause: Rated 36,500-lumen output is specified only up to 35 C ambient; above that, or with a fouled radiator/degraded coolant, the laser bank self-protects by reducing output.
- Step-by-step fixGet the fix →
Projector much dimmer than rated / only about half brightness
Likely cause: The dual-voltage design intentionally drops to limited brightness on low-line power (which also more than doubles laser life).
- Step-by-step fixGet the fix →
Red/green/blue color fringing or misconvergence on screen
Likely cause: The 3DLP engine uses three separate 1.38" imagers; slight mechanical shift shows as color fringing, correctable by the built-in convergence adjustment.
