The image isn’t square, but trapezoid-shaped.

Make sure the projector isn’t placed off to one side of the screen, 
at an angle. Place the projector directly in front of the center of 
the screen, facing the screen squarely.

If you’ve tilted the projector upward by extending the legs, the 
image will be broader at the top. Hold down the 
+ or – side of the 
Keystone button on top of the projector until the image is 
square. 
The image contains static or noise.

If you’ve connected a device to the Computer 2/Component 
Video port, make sure the 
BNC option in the Setting menu is 
correct. See the Administrator’s Manual.

If you’re using a computer cable longer than 6 feet, 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; 
see your laptop’s manual for instructions.
The image is blurry.

There may be dirt or smears on the lens. Clean the lens as 
described in the Administrator’s Manual.

Adjust the focus using the focus ring.

Adjust the Sharpness setting in the Video menu (see the 
Administrator’s Manual). 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.  
						

							Solving Problems67
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 (such as the body of a letter), you may 
notice one or more vertical stripes or bands, or some of the 
characters may look heavy or blurred. Press 
Auto on the remote 
control or the   
Enter button on the control panel. 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 buttons on the control 
panel (or using the Video menu as described in the Administrator’s 
Manual): 
1. Fill the screen with an image containing fine detail when 
making these adjustments. For example, in Windows you can 
click 
Start, Settings, and Control Panel, then double-click 
Display; select a pattern to appear as your desktop 
background. If this option isn’t available, try projecting black 
text on a white background (such as a letter).
2. Press the 
Tracking – and Tracking + buttons to eliminate 
vertical stripes. 
3. Press the 
Sync – and Sync + buttons to increase the 
sharpness of the image.

The colors of the image are not right.

The color balance may be incorrect. If you’re displaying a 
computer image, use the 
Gamma option in the projector’s Video 
menu to adjust the balance of red, green, and blue. If you’re 
displaying video, adjust the 
Color, Tint, and Gamma settings on 
the Video menu. Also try adjusting the 
Color Setting option in 
the Advanced menu.

Check your computer display settings to correct the color balance.
There is no sound.

Try turning up the volume. Hold down the Shift button and 
press the right side of the 
Volume button (control panel) or press 
the right side of the
 Volume button (remote control).

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

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 2.

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 35.

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 right-clicking the sound icon on your Windows 
desktop. 

The wrong source may be selected. Press the Comp/Easy-MP or 
Video button on the control panel—or the Comp1, 
Comp2/YCbCr, Easy-MP, or Video button on the remote 
control—to select the proper source. Allow a few seconds for the 
projector to sync up after pressing the button.
note
Because of the different 
technologies used, your 
projected image may not 
exactly match the colors on 
your laptop or computer 
monitor.

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, have a direct 
line-of-sight to the projector’s front or back sensor, and are no 
more than 30° to the left or right, or 15° above or below, the 
sensor.

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.

Dim the room lights and turn off any fluorescent lights. 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 your computer’s cursor with the remote 
control.

Make sure the mouse cable is securely connected to both your 
computer’s mouse port (using the main cable) and the projector’s 
mouse port. See page 34 for details.

Make sure you’ve used the correct cable. The PS/2 mouse cable 
and Macintosh mouse cable look similar, but they aren’t identical. 
Check the label on the end of the cable.

Solving Problems with EasyMP.net
You cannot send your presentation to the projector.

Make sure the projector is plugged into a power outlet (the 
projector doesn’t have to be turned on, though). It must also be 
properly connected to your network, as described in the 
Administrator’s Manual.

Make sure the memory card is inserted in the projector’s 
PCMCIA slot. See page 16.
You’ve copied your presentation to the projector, but it 
doesn’t show up in Easy View.
Make sure the presentation file is in one of the compatible formats 
listed on page 8.
Projected images don’t fit on the screen. 
Select Fit to screen in Easy View, as described on page 18.
Your presentation doesn’t look exactly the same as it did on 
your computer screen.
Certain PowerPoint special effects are unavailable when using 
EasyMP.net, including sound effects. Microsoft Word and Excel files 
may not display with the same font you used on your computer. See 
Chapter 8 of the Administrator’s Manual for more information.
The remote control’s highlighting tools don’t work when 
using EasyMP.net.
The numbered buttons on the remote control can be used to highlight 
images only when you’re projecting directly from a computer or video 
source. Use EasyMP’s highlighting tools instead; see page 20.

When using the EMP Tablet software, you can’t move the 
cursor all the way to the edge of the screen.
You may need to move or resize the EMP Tablet window on your 
computer’s desktop. You can also drag the toolbar out of the way, if 
necessary.
When using EMP Scenario, you can’t drag a PowerPoint file 
into the scenario window.
You have to double-click the PowerPoint file in EMP Scenario’s file 
window to open the individual slides; then drag each slide from the 
thumbnail window into the scenario window.
