What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.

Image too blurry to read the menu (new lens / focus way off) — how to fix focus blind
Likely cause: Calibration re-homes the motors to the installed lens.
- Step-by-step fixGet the fix →
Zoom / focus / lens shift won't respond from the remote, keypad or web UI
Likely cause: Either setting stops the projector from driving the lens motors; calibration re-learns the lens travel limits.

Image discoloration / color cast NOT fixed by a new lamp
Likely cause: 3DLP separates white light into R/G/B via prism onto three DMDs; color errors come from filter state (YNF), lamp spectrum/age, color processing, or the prism/DMD block — never a color wheel.

Lamp(s) switch off on their own for ~15 min (lamp LEDs flashing green)
Likely cause: Mercury lamps benefit from periodic off-time on 24/7 duty; the projector does it automatically.

Christie M-Series specs (power, weight varies)
Likely cause: Draw depends on lamp wattage (200/350/450W) and dual vs single lamp; the license label is the authoritative per-unit figure.
- Step-by-step fixGet the fix →
Dim image / short lamp life
Likely cause: Mercury lamps lose output with age; M Series offers 200/350/450W lamp variants with different lifetimes.
- Step-by-step fixGet the fix →
Over-temperature shutdown / thermal warning
Likely cause: Heat removal depends on airflow and ambient; the unit is only rated to 40 °C and 10,000 ft.
- Step-by-step fixGet the fix →
Pulling power at load-out / unplugging too soon
Likely cause: Lamp cooling fans need to run after the lamps are extinguished.
- Step-by-step fixGet the fix →
Status LED meanings (power LED flashing red, lamp LED amber/red)
Likely cause: Quick read of the LEDs tells you standby vs fault vs upgrade before touching anything.
- Step-by-step fixGet the fix →
Software/firmware upgrade procedure (.shar)
Likely cause: The .Shar bundles all board firmware; interrupting the post-upgrade first boot can corrupt the image-processor flash and brick the card.
- Step-by-step fixGet the fix →
LCD/status alarm — how to read warning vs critical
Likely cause: M Series flags conditions in two tiers; distinguishing warning from critical tells the tech whether they can keep running or must stop immediately to avoid damage.
- Step-by-step fixGet the fix →
Color/convergence misalignment (colored fringing on edges)
Likely cause: A 3DLP engine combines three panels; small mechanical drift shows as color fringing that the electronic convergence grid can pull back into register.
