Common Eiki / 4K7-HS 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 →
Choosing / calculating the right lens and throw for a room
Likely cause: Gives the tech the exact throw math to pick a lens by throw distance and image width, plus the ILS memory feature that makes multi-config shows repeatable.
- Step-by-step fixGet the fix →
Control / integration (RS232, network, multi-projector blend)
Likely cause: Points integrators at the exact API doc and the native Twist engine rather than external processors, which is how HS-series blends are normally driven.

How to update firmware and what is the current version
Likely cause: v1.6.0 is the latest release confirmable on Christie's site as of Jul 2026.
- Step-by-step fixGet the fix →
Image looks dim, discolored, or brightness dropping over time
Likely cause: Separates the two failure paths: laser aging (slow, diagnosable in menu) vs color-wheel/calibration (sudden tint or flicker).

Power / electrical planning for the 4K7-HS
Likely cause: Lets the tech size the circuit and rigging load correctly - important because full-power draw is higher than the ECO2 figures and the unit is ~80 lb.

Reading the front/rear Status LED - what each color means
Likely cause: Christie HS-series (4K7-HS/4K10-HS share the D13 HS chassis) uses a single multi-color Status LED plus a Shutter LED.
- Step-by-step fixGet the fix →
Status LED flashing YELLOW but projector keeps running
Likely cause: A clogged filter or hot LD driver raises internal temps; the projector warns (yellow) before it has to protect itself (red).
- Step-by-step fixGet the fix →
Status LED is flashing RED and/or projector shut itself down
Likely cause: The HS thermal-protection logic drops the laser and shuts down on any of these faults to protect the DMD and laser drivers; clearing the physical cause (airflow/filter) resolves the majority of field cases.
