Fixing Problems
Sound problems
If no sound is coming out of the projector:
❏ Be sure you have an audio cable securely connected between the
projector and the input device.
❏ Be sure that the mute and volume settings are correct on the input
device, such as a computer, DVD player, or camcorder.
❏ Open the on-screen menu and select Quick choice. Check the
following settings:
◆
Mute is turned off.
◆
Volume is correct.
Interruption problems
If the lamp indicator or temperature indicator turns on or blinks:
❏
If the lamp indicator blinks, the lamp is not able to light. Wait for
the projector to cool, then try starting it again.
❏ If the lamp indicator is on or blinking, unplug the projector after
it cools down. Remove and reinstall the lamp module. If this does
not fix the problem, install a new lamp.
❏
If the temperature indicator turns on or blinks, the projector is too
hot. See the following problem.
If the projector suddenly shuts down and the temperature light turns on:
❏ If the temperature light is blinking, the fan is not working. Allow
the projector to cool for several minutes.
❏
If the temperature light is steady, the projector has overheated.
Allow it to cool for several minutes.
❏ If airflow is obstructed, remove the obstruction.
❏
If possible, remove any sources of excess heat in the room.
❏
If the condition occurs after restarting the projector, contact HP
to have the projector serviced or repaired.
