Projector does not move from standby to full power mode

• Check the touch panel controller (TPC) for error messages.
• If a failure with PIB communications exists, reseat the board.
• Check the Ethernet status LED on the rear of the TPC.
• Verify that the internal fans are operating.
• Look through the rear right side grille and verify that the upper right LVPS (Low Voltage Supply)
and the lower left main input LEDs are on. If the green LEDs are not on, check the breaker
wiring to the terminal strip.
• Check all of the harness connections between LVPS and backplane.
• Replace the LVPS.

DMD over-temperature warning

• Tap Menu > Status and then Temperatures in the left pane. Verify if the DMD temperatures
are too high. If the temperatures are too high, cool the projector.
• Check the condition of the air filters and clean them if they appears to be dirty.
• Verify that all fans are operating.

Lamp functionality

Lamp does not ignite

• Tap Menu > Advanced Setup > Lamp History and verify the number of hours the lamp has
operated. Replace a lamp nearing the end of its operational life.
• Tap Menu > Status and then Interlocks in the left pane. Check and correct all interlock
failures.
• Tap Menu > Status and then All Alarms in the left pane. If a ballast communication error has
occurred, restart the projector and turn the lamp on.
• Tap Menu > Status and then Temperatures in the left pane. Verify if the DMD temperatures
are too high. If the temperatures are too high, cool the projector. Ensure the projector is
properly ventilated and the air filters are not blocked.
• Listen for a clicking noise that indicates the ballast is attempting to strike the lamp. If you do
not hear a clicking noise, there might be a problem with the ballast. Contact a Christie
accredited service technician to resolve the issue.
• If you hear a brief clicking noise, but the lamp does not ignite, replace the lamp.

Lamp suddenly turns off

• Tap Menu > Advanced Setup > Lamp Power/LiteLOC Setup. Increase the lamp power.
