Troubleshooting; Power; Lamp - Christie roadie 25k User Manual

If the projector does not appear to be operating properly, note the symptoms present and use the following guide to
assist you. If you cannot resolve the problems yourself, contact your dealer for assistance.
NOTE: A qualified service technician is required when opening the projector to diagnose any "probable cause".

1. Check for green "Proj. Status" light on projector. If not on, check all breakers on
the ballast and at the wall.
2. Is the ballast breaker staying on? If it is "tripping" to OFF position, there is an
electrical problem requiring investigation by a certified electrician.
'
1. Make sure the ballast is on (indicated by the breaker in the "up" position), and
that all 4 ballast cables are properly connected to the projection head.
2. If the lamp won't ignite, there may be an interlock failure such as an open lamp
door, failed lamp fan, airflow problem at the extractor, etc. The LCD status
display also indicates this.
3. If a temperature is too high ("DMD over critical temp limit", e.g.), the lamp will
not ignite until the temperature is low enough. Cool the projector and try again.
4. With the lamp off, press
status display window matches that of the installed lamp (2.0 kW, 3.0 kW, 4.5
kW or 6.0 kW). This should also be indicated on the Lamp Installed label.
5. Check lamp anode and cathode connections (qualified service technician
required).
6. Check communication cable connections between the ballast and projection head.
7. For suspected communication failures, power-down the projector and try again.
8. If the lamp does not ignite after a second and third try, replace the lamp.
9. If there is no "buzzing" or high voltage "snaps" indicating that the igniter is
attempting ignition, there may be a problem with the igniter itself (Christie
service required).
10. If there is a brief "buzz" or snapping sound (which is an attempt at ignition) but
the lamp still does not ignite, the lamp likely needs to be replaced.
