5.2.1 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, click the LED in the top, left corner to open the Status
window. (Figure 5-3). Alternatively, click the
and select Status. With the Status window open, click
Interlocks. If a failure is shown, interlock needs to be
cleared before the lamp will light.
3. 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.
4. Check for an alarm condition. From the Main panel, click the
LED in the top, left corner to open the Status window. Click
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.
5. 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).

5.2.2 Lamp Suddenly Goes OFF

1. Check the lamp power in the Advanced Setup: Lamp Power/LiteLOC Setup window. Try increasing the
lamp power. NOTE: Older lamps may not reliably operate at significantly lower than rated power.
2. An interlock may be interrupting lamp function. From the Main panel, click the LED in the top, left corner
to open the Status window. Click Interlocks. If a failure is shown, interlock needs to be cleared before the
lamp will light.
3. If EVB errors occur, check the door interlock.
4. The DMDs may be overheated. Check for an alarm condition. From the Main panel, click the LED in the
top, left corner to open the Status window. Click 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.
5. Replace the lamp. For more information, refer to
