Start-up problems
If no lights or sounds turn on:
❏Ensure that the power cable is securely connected to the projector 
and the other end is plugged into an outlet with power.

❏Verify that lid of the projector is latched shut.
❏Press the power button again.
❏Reset the projector by turning the main disconnect switch off, 
wait 60 seconds, then turn it on again.
If nothing is projected, but the projector seems to start up:
❏Ensure the lens cap has been removed. 
❏If the lamp indicator is on, replace or reinstall the lamp module.
❏If the temperature indicator is on, turn off the projector and allow 
it to cool before restarting it. If the warning lights turn on again, 
contact HP for assistance.
If the projector makes a “ticking” sound, if the projector lamp does not  
turn on, and if warning lamp light is on: 
❏The projector lamp is too hot to light. Turn the projector off and

Troubleshooting
❏Ensure the projection screen is 1.5 to 14 m (5 to 46 ft) from the 
projector. It can be farther if a long range add-on lens is installed.
❏For a computer connection, set the display resolution on the 
computer to 1024 x 768.

Troubleshooting
If the projected colors seem completely wrong:
❏If the super-bright button on the projector is lit, the picture  
is displayed in grayscale. To display colors, press the business 
graphics button or the theatre video button on the projector or 
remote control.
❏For a YPbPr or RGB input device, be sure all the video 
connectors are correctly matched.
❏Ensure the pins on the cable connectors are not bent or broken.
❏Open the on-screen menu and select adjust picture > Color 
space. Try changing the selection.
❏Open the on-screen menu and select help > Diagnostics. Run 
color tests.
❏Reset the picture settings to the factory-default settings. See the 
following problem.
If the picture settings are completely wrong and you cannot fix them:
❏Reset the projection settings to the factory-default settings. To do 
this, hold down these three buttons on the projector for 5 seconds: 
back + up-arrow + auto sync. (This does not reset network 
settings.)
If a DVI device causes an error message or garbage on the screen:
❏Certain high-definition digital sources incorporate HDCP 
(High-bandwidth Digital-Content Protection) content protection. 
Such content cannot be displayed by this projector. If the device 
has another output port, such as YPbPr, try connecting that port to 
the projector.
If a VGA monitor displays a bad picture for certain inputs:
❏If you connect certain types of VGA monitors to the VGA output 
port, it might have a blank or erratic display for video inputs, but 
it should have a good display for computer graphics input. If this 
occurs, trying using a different type of monitor.
If the projector stops responding to all controls:
❏If possible, turn off the projector. Then turn the main disconnect 
switch off, wait 60 seconds, then turn it on again.

Troubleshooting
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 audio. Check the following 
settings:
◆Mute is turned off.
◆Volume is correct.
◆Internal speakers are turned on.
◆Audio input select shows the correct audio input for your 
video port.
If the projector speakers interfere with an external audio system:
❏Open the on-screen menu and select audio > Internal speakers. 
Then, disable the internal speakers.

Troubleshooting
Interruption problems
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. 
If the lamp shuts off during a presentation:
❏A minor power surge might cause the lamp to shut off. Wait a few 
minutes, then power on the projector.
❏The lamp module might have burned out. Replace the lamp 
module.
If the lamp burns out or makes a popping sound: 
❏When the lamp reaches its end of life, it might burn out and make 
a popping sound. If this happens, the projector will not turn back 
on until the lamp module has been replaced. 
❏If the lamp breaks, contact HP about repairs that might be 
required.

Troubleshooting
Remote control problems
If the remote control does not operate: 
❏If the indicator light on the front of the remote control blinks 
when you press buttons, the remote control is working properly.  
If the light does not blink, install two new AAA batteries in the 
remote control.
❏Be sure nothing is blocking the infrared receivers on the front and 
back of the projector. Move to within 9 m (30 ft) of the projector.
❏Open the on-screen menu and select help > Diagnostics. Run 
remote control tests.
If only the mouse and page up and down buttons do not work: 
❏Be sure you have a USB connection between the projector and the 
computer.
❏Open the on-screen menu and select help > Diagnostics. Run 
remote control.
Networking problems
If you cannot access the projector via the web:
❏Check that you are using the correct IP address. The projectors IP 
address is shown in the on-screen menu on the projector.
❏Check the network cable connections at the projector and at the 
wall.
❏Check the left indicator light on the LAN port on the projector. If 
the light is not on, the network might not be active. Try a different 
cable or check the network outlet at the wall using a computer.
❏If your model includes an L1581A Advanced Connectivity 
Module, see the L1581A manual.
❏Check whether the projector’s IP address shown in the on-screen 
menu is 169.254.x.x. If the projector is set to use a DHCP server, 
this address means no DHCP server is available. If the projector 
does not use a DHCP server, this address means no IP address is
