							Solving Problems65
The image contains static or noise.

If you’re using a computer cable longer than 6 feet, or an 
extension cable, the image quality may be reduced.

Keep your computer and video cables separated from the power 
cord as much as possible to prevent interference.

The video signal may be split between the computer and the 
projector. If you notice a decline in the projected image quality 
when the image is displayed simultaneously on your laptop 
computer and the projector, turn off the laptop’s LCD display.
The image is blurry.

There may be dirt or smears on the lens. Clean the lens as 
described on page 52.

Make sure the lens is fully extended.

Adjust the focus using the focus ring.

Make sure the lens is not fogged by condensation. You may need 
to wait before using the projector after moving it from a cold 
environment.

Adjust the Sharpness setting on the Video menu (see page 41). 
When you change video settings, you should be able to see the 
effect on the screen immediately. If you’re projecting from a 
computer, you may also need to adjust the Tracking and Sync as 
described in the next section. If you don’t like the new settings, 
you can always select 
Reset to return to the factory default 
settings.  
						

							66Solving Problems
You see vertical stripes or the image still looks blurry after 
trying the solutions in the previous section.

If you’re projecting from a computer and displaying an image that 
contains a lot of fine detail, you may notice one or more vertical 
stripes or bands, or some of the characters may look heavy or 
blurred. Press the 
Auto button on the remote control. This resets 
the projector’s tracking and sync settings.

If further adjustment is needed, you can fine-tune the Tracking 
and 
Sync settings manually using the Video menu as described 
on page 41. 
1. Fill the screen with an image containing fine detail when 
making these adjustments. For example, in Windows you can 
select a pattern to appear as your desktop background. If this 
option isn’t available, try projecting black text on a white 
background.
2. Adjust the 
Tracking to eliminate vertical stripes. 
3. Adjust the 
Sync to increase the sharpness of the image.
The colors of the image are not right.

If you’re displaying a computer image, use the Gamma option in 
the projector’s Video menu to adjust the color. If you’re 
displaying video, adjust the 
Color, Tint, and Gamma settings on 
the Video menu. 

Try adjusting the Color Temp setting on the Advanced menu.

Check your computer display settings to correct the color balance.
note
Because of the different 
technologies used, your 
projected image may not 
exactly match the colors on 
your laptop or computer 
monitor. 
						

							Solving Problems67
There is no sound.

Try turning up the volume. Press the right side of the Volume 
button on the remote control.

If you’re using a VCR or other video source, make sure the 
volume is not turned all the way down or muted. Also, make sure 
the cables are connected correctly, as described in Chapter 1.

If your presentation includes computer audio, make sure the 
volume control on your computer is not turned all the way down 
or muted. Make sure the audio cable is securely connected to both 
the projector and your computer’s   headphone jack or   
audio out jack. See page 14 (for laptops) or Appendix A (for other 
systems).

Make sure the Windows volume controls on your computer are 
not turned all the way down or set to Mute. You may be able to 
check this by clicking the volume control in your Windows 
System Tray (lower right corner of the screen). 

Make sure the A/V Mute button is not enabled.

The wrong source may be selected. Press the Source button on 
the projector—or the 
Comp, Video, or S-Video button on the 
remote control—to select the correct source.    
						

							68Solving Problems
Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.

Make sure the remote control is turned on. 

Make sure you are within 30 feet of the projector, and within 
range of the projector’s front or back sensor (approximately 30° to 
left or right and 15° above or below).

The remote control batteries may not be installed correctly or may 
be low on power. To test the batteries, press the  light button. 
The other buttons on the remote should light up temporarily. If 
they don’t, you need to change the batteries as described on 
page 28.

Dim the room lights and turn off any fluorescents. Make sure the 
projector is not in direct sunlight. Strong lighting, especially 
fluorescent lights, may affect the projector’s infrared receivers.

Turn off any nearby equipment that emits infrared energy, such 
as a radiant room heater.
You can’t control the mouse pointer with the remote 
control.
Make sure the mouse cable is securely connected to both your 
computer’s mouse port or USB port and the projector’s mouse port. 
For details, see page 13 (for laptops) or Appendix A (for other 
systems).

Appendix A: Connecting to Additional Equipment71
Appendix A: Connecting to 
Additional Equipment
This appendix explains how to connect the projector to a desktop 
computer or Macintosh, or a high-end workstation. 
The following information is covered:

Installing the projector

Connecting to a PC desktop computer

Connecting to a desktop Macintosh

Connecting to a high-end workstation 
						

							72Appendix A: Connecting to Additional Equipment
Installing the Projector
The projector can be installed for three different viewing setups: front 
projection, ceiling mounting, or rear projection onto a 
semi-transparent screen.
To project from overhead, you’ll need to select 
Ceiling in the 
projector’s Advanced menu. To project from the rear, select 
Rear 
Proj
. See page 48 for more information.
If you’re ceiling-mounting the projector and you place it above screen 
level, you’ll have to tilt it down to position the image on-screen. This 
causes the image to lose its square shape. You can then correct the 
distortion by using the 
Keystone function in the projector’s menu 
system (see page 46).
If you place the projector’s lens so it’s level with the top of the screen, 
the image will be square and you won’t have to adjust it. If you place 
the lens lower than the top of the screen, you’ll have to tilt the 
projector upward if you want to fill the whole screen with the image. 
Connecting to an External Audio System
The projector’s internal speaker is loud enough for most rooms. 
However, if your installation requires maximum volume and sound 
quality, you can connect the projector to external speakers or a public 
address (PA) system. If you’ve connected a computer and video 
source, the projector will automatically switch the audio whenever you 
switch sources (see page 30).
To connect the projector to an external sound system, you will need 
an RCA-to-3.5 mm stereo audio cable, which may be included with 
your sound system, or may be purchased from an electronics store.  
						

							Appendix A: Connecting to Additional Equipment73
Before you start, make sure the projector and speakers or PA system 
are turned off.
1. Connect the cable’s 3.5-mm stereo miniplug to the projector’s 
Audio Out jack.
2. Connect the RCA plugs to the speaker or PA system. Insert the 
cable’s red plug into the 
Audio R jack, and the white plug into 
the 
Audio L jack of the external speaker system.
Connecting to a PC Desktop Computer 
You can connect the projector to any IBM compatible PC. This 
section includes instructions for the following:

Connecting the computer cable 

Connecting the mouse cable (if you want to use the remote 
control as a mouse)

Connecting an optional audio cable (if you’ll be projecting with 
audio)
When you connect the projector to a desktop computer, you cannot 
view your display on the computer monitor.
Follow the steps in each section for the cables you need to connect. 
Before beginning, turn off the projector and computer if they are on. 
						

							74Appendix A: Connecting to Additional Equipment
Connecting the Computer Cable
1. Disconnect the monitor cable from the video port on the back of 
the computer. 
2. Connect one end of the computer cable to the projector’s 
Computer port.
3. Connect the other end of the computer cable to the computer’s 
video port.
4. Tighten the screws on the connectors.
