Lamp burns out or makes a
popping sound
When the lamp reaches its end of life, it
will burn out and may make a loud
popping sound. If this happens, the
projector will not turn back on until the
lamp module has been replaced.
Contact your local Compaq authorized
dealer, seller, or reseller to purchase a
replacement lamp module. To replace
the lamp, follow the procedures in the
“Replacing the Projector Lamp Module”
section of Chapter 7.

An over-temperature event has been
detected. This usually occurs when
either the airflow to the unit has been
obstructed or a fan has failed. If airflow
is obstructed, remove the obstruction,
unplug the projector, re-plug the
projector, and restart. If a fan has failed
or an over-temperature event occurs a
second time, have the projector
serviced or repaired.
