Maintaining the projector
Getting the projector status
To get the projector status, press the menu button on the projector or remote 
control and go to Help. This screen shows information and status for the 
projector.
Cleaning the projector lens
You can clean the front lens of the projector using the following 
recommendations. You cannot clean any of the internal surfaces.
■To minimize the risk of damaging or scratching the lens surface, blow dust 
particles off the lens with clean, dry, deionized air.
■If this method does not work, use the following method:
a. Wipe the lens in a single direction with a clean, dry cloth. Do not wipe 
back and forth across the lens.
b. If the cloth is dirty or smears the lens, wash the cloth. If the cloth is still 
dirty after washing it or the fabric is damaged, replace it.
Ä
Cleaning requires special consideration:
■Do not spray any type of fluid or cleaner directly on the lens surface. 
Cleaners might damage the lens.
■Do not use fabric softener when washing a cleaning cloth or softener 
sheets when drying the cloth. Chemicals on the cloth might damage the 
surface of the lens. 
■Do not store a cleaning cloth in contact with the lens for a long time 
because doing so contaminates the lens with dye from the cloth. The cloth 
can be contaminated if left in the open air.

Maintaining the projector
Replacing the lamp module
As the projector operates over time, the brightness of the projector lamp 
gradually decreases and the lamp becomes more susceptible to breakage. You can 
install a new lamp at any time to bring the projector up to factory-fresh 
brightness. We recommend replacing the lamp if a warning message is displayed.
Å
Replacing the lamp module requires special consideration:
■To reduce the risk of injury, be careful when removing the lamp module as 
broken glass might be present. If the lamp is broken, contact HP about 
repairs that might be required due to glass fragments.
■The lamp contains a small amount of mercury. If the lamp breaks, 
adequately ventilate the area where the breakage occurred. Disposal of 
this lamp might be regulated due to environmental considerations. For 
disposal or recycling information, contact your local authorities or the 
Electronic Industries Alliance at http://www.eiae.org.
■Because the lamp assembly operates at a very high temperature, wait 30 
minutes before removing the lamp module.
1. Turn off the projector and allow it to cool for 30 minutes.
2. Unplug the power cord.
3. Loosen the 3 screws 
1 on the front cover and pull out the front cover until 
the tab 2 at the right end comes out of the projector 3.
4. Loosen the two screws 
4 on the lamp module, and pull out the module 5.

5. Insert the new lamp module into the projector and tighten the two screws.
6. Insert the tab on the front cover into the slot in the projector and close the 
cover.
7. Tighten the screws that hold the cover.
8. Turn on the projector. If the lamp does not turn on after the warm-up period, 
try reinstalling the lamp.
9. Press menu, go to Setup > Reset lamp hours, and press ok.
Replacing the battery in the remote 
control
1. On the back of the remote control, push in the tab 1 and remove the battery 
cover 
2 to reveal the batteries.
2. Remove the old batteries and install two new AAA batteries 
3.
3. Install the battery cover.
When discarding old batteries, contact your local waste-disposal provider 
regarding local restrictions on the disposal or recycling of batteries.

http://www.hp.com/support for additional information. To contact HP, see 
Chapter 7, “Support and warranty.”
Warning light problems
If both red warning lights are blinking:
❏Allow the projector to cool down after it turns off. If this condition 
occurs after you restart the projector, an internal component has failed. 
Contact HP for assistance.
If the red temperature light is on or blinking:
❏Allow the projector to cool down after it turns off. Be sure that nothing is 
near or blocking the vents on the projector, and that the vents are free of 
lint and other objects. Remove any sources of excess heat in the room. 
Observe temperature and altitude limits (see “Specifications” on 
page 69). If the warning light turns on or blinks after you restart the 
projector, contact HP for assistance.

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.
❏If you put a disc in the DVD tray but the projector did not turn on, the 
disc is not recognized. Try a different disc.
❏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.

If the image is out of focus:
❏Be sure the lens cover is open.
❏While displaying the on-screen menu, adjust the focus ring. (The image 
size should not change; if it does, you are adjusting the zoom, not the 
focus.)
❏Ensure the projection screen is 1 to 10 m (3 to 33 ft) from the projector.
❏Check the projection lens to see if it needs cleaning.
❏For a computer connection, set the display resolution on the computer to 
800×600 pixels. If the computer has multiple monitors, adjust the 
resolution of the monitor assigned to the projector.
❏For a computer connected to the S-video port, the picture cannot be as 
high resolution as what you see on the computer display.
If the image is too small or too large:
❏Adjust the zoom ring on top of the projector.
❏Move the projector closer to or farther from the screen.
❏On the projector or remote control, press the picture mode button one or 
more times to see if one of the picture modes makes the image the correct 
size.
❏Press menu, go to Picture > Customize picture mode > Stretch. Try 
the different settings.
❏If the source device sends wide-screen output, press menu, go to Picture 
> Shape settings, and try setting Widescreen input to Ye s .  Otherwise, 
set it to No.
If the image has slanted sides:
❏As much as possible, reposition the projector so that it is centered on the 
screen and below the bottom of the screen.
❏On the projector or remote control, press the keystone button until the 
sides are vertical.

If the picture is not clear (ghost images, smearing, poor quality):
❏Be sure the video cable you are using is coaxial cable rated at 75 ohms. 
Any other cable or impedance rating can reduce picture quality.
❏The video cable connecting the video source to the projector probably 
must be higher quality, especially if the cable is longer than about 3 m 
(10 ft). Low-loss cable is recommended for longer distances to avoid 
degrading or losing the picture
If a DVI source is not displayed when the DVI port is selected:
❏Press menu, go to Setup > DVI compatibility, and select Standard

							60 User’s Guide
Fixing problems
❏The type of disc you inserted might not be supported by the internal 
DVD player. If so, you cannot play this type of disc.
❏For a DVD, check its region code. Most DVDs have a region code 
marked near the center hole. Compare its region code with the region 
code for a DVD that plays properly on your projector. The projector can 
play DVDs from only one region.
If a disc in the tray does not automatically play:
❏A disc automatically starts playing only at the time you close the tray. If a 
disc is already loaded in the tray, press the play/pause button to start 
playing.
❏If the projector is off, nothing happens if you insert a disc that is not 
supported by the internal DVD player.
If some pictures on a CD do not show:
❏Some pictures with very high resolution (high number of pixels) cannot 
be displayed. Convert them to standard JPG format with a lower 
resolution.
If you cannot display a DVD menu:
❏Press the DVD menu button.
❏The current DVD probably does not have a menu.
If a ! icon appears on the screen:
❏You pressed a button that is not supported by the disc or by the DVD 
player in the current situation. The button is ignored.
Sound problems
If no sound is coming out of the projector:
❏If you are playing an external source, be sure you have an audio cable 
securely connected between the source device and the projector’s audio 
input.
❏Be sure a headphone is not plugged into the headphone jack. A 
headphone connection disables the internal speakers.
❏Press menu, go to Sound, and check that Mute is turned off and Vo l u m e 
is correct.
❏Press menu, go to Sound > Internal speakers, and be sure the speakers 
are turned on.
