4.2.1 Lamp Does Not Ignite

1. Verify the hours currently on the lamp. If the hours are close to
the typical lamp life, replace the lamp.
2. Check for interlock failures. From the Main panel on the TPC,
tap the LED in the top, left corner to open the Status window.
Alternatively, tap the Menu button and select Status. With the
Status window open, tap Interlocks. If a failure is shown,
interlock needs to be cleared before the lamp will light.
3. For EVB communication failures, re-boot and try again.
4. If the All Alarms field of the Status window shows a Lamp
Power Supply (LPS) communication problem, re-boot the
projector and try turning the lamp ON again.
5. Check for an alarm condition. From the Main panel, tap the LED in the top, left corner to open the Status
window. Tap Temperatures. If a DMD temperature is too high, the lamp will not ignite. Cool the projector
and try again. Ensure there is proper ventilation, air filters are not blocked and liquid cooling reservoir has
coolant and is circulating.
6. Listen for a "clicking" noise to indicate the LPS is attempting to strike the lamp. If the lamp does not ignite
after the second attempt, check the power level of the lamp in the Advanced Setup: Lamp Power/LiteLOC
Setup window. The lamp power may be too low, especially if the bulb is old. If the lamp power is
acceptable, replace the lamp. For more information, refer to
Alternatively, if you hear a brief "click", but no light appears, the lamp likely needs replacement. If you do
not hear anything, it may indicate a problem with the LPS (Christie-trained service required).
