Fixing problems
If the red lamp light is on or blinking:
❏
Allow the projector to cool down after it turns off. If the warning light
turns on or blinks after you restart the projector, install a new lamp. If
this occurs after you install a new lamp module, remove and reinstall the
lamp module. If a new lamp does not fix the problem, contact HP for
assistance.
If the red lamp light is flickering quickly:
❏
Check that the cover around the lamp at the front of the projector is
correctly installed and fully attached. Check the tab at the right side of
the cover and the screw at the left side.
Start-up problems
If no lights or sounds turn on:
❏
Be sure that the power cable is securely connected to the projector and
the other end is plugged into an outlet with power.
❏
Press the power button again.
❏
Unplug the power cord for 15 seconds, then plug it in and press the
power button again.
Picture problems
If a “waiting” message is displayed on a blank screen:
❏
Press the source button on the projector or remote control one or more
times until the correct source name is selected.
❏
Be sure the external source is turned on and connected.
❏
For a computer connection, ensure your notebook computer’s external
video port is turned on. Refer to the computer manual. On some
notebooks, for example, press the Fn + F4 or Fn+F5 function keys to turn
on the external video port.
If the wrong input source is displayed:
❏
Press the source button on the projector or the remote control one or
more times to select another active input source.
