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.
If nothing is projected but the projector seems to start up:
❏
Be sure the lens cap has been removed.
❏
Check the front of the projector—the latch for the lamp module
should be down.
❏
If the lamp indicator is on, replace or reinstall the lamp module. If
the lamp indicator is blinking, turn off the projector and allow it
to cool before restarting it—replace the lamp module if the
indicator continues to blink.
❏
If the temperature indicator is on or blinking, turn off the
projector and allow it to cool before restarting it. If the warning
light turns on or blinks again, contact HP for assistance.
If the projector makes a “ticking” sound, if the projector lamp does not turn on,
and if the lamp indicator is on or blinking:
❏
The projector lamp is too hot to light. Turn the projector off and
wait for it to cool before turning it on again.
❏
The projector lamp is not making a good connection. Turn off the
projector and allow it to cool. Then, on the front of the projector,
slide the latch for the lamp module up and down. Be sure it is all
the way down.
❏
The projector lamp has reached the end of its life. Replace the
lamp.
