Lamp suddenly turns off
The lamp unexpectedly turned off.
Resolution
•
Increase the lamp power.
•
Review and correct all interlock failures.
•
Ensure the touch panel controller (TPC) has no temperature or fan RPM warnings.
If all fans are running normally and the air filters are not blocked, the ambient air temperature
may exceed the maximum operating specification. If possible, reduce the ambient
temperature.
•
Ensure no heat sources are exhausting into the projectors intake, or move the projector to a
cooler environment.
•
Verify the number of hours the lamp has operated. A lamp nearing the end of its operational
life should be replaced.
•
Check for a cross-connected condition.
A cross-connection hazard can occur when installing multiple projectors at once. A fire hazard
exists if a lamp power supply interlock cable is connected to a different projector than its lamp
power cables.
