■Check that the PPower light is green, not flashing, and the 
A/V Mute slide is open. Also press the A/V Mute button on the 
remote control to see if the picture was turned off temporarily.
■If the projector doesn’t turn on, the Operation Lock may be 
enabled. Press and hold the 
Enter button on the projector for 
7 seconds to release the lock.

return to full display.
■Try pressing the Aspect button on the remote control to select a 
different aspect ratio (4:3, 16:9, or another available setting).
■Make sure your computer’s resolution setting is correct and dual 
display is not activated. Ideally, it should be 1024 × 768 to match 
the projector’s native resolution. If this option isn’t available, 
select another compatible video format. See page 107. 
■Windows:
Right-click the desktop, select 
Properties, click the Settings 
tab, and select a different resolution. 
■Macintosh OS X:
On the Apple menu, choose

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.
■If you’re projecting from a composite or S-Video source, check 
the 
Video Signal setting in the Signal menu. In most cases, leave 
it set at 
Auto. If you’re using a 60-Hz PAL video source, change 
this setting to 
PAL60. See page 56 for details.

							86Solving Problems
You see vertical stripes or the image still looks blurry after 
trying the solutions in the previous section.

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 
Enter/Auto button on the remote control to 
automatically reset the projector’s tracking and sync settings.
■If necessary, you can manually adjust the Tracking and Sync 
settings on the Signal menu as described on page 55. 
To help you adjust these settings, fill the screen with a detailed 
image, such as a desktop background pattern or black text on a 
white background. Adjust the 
Tracking setting to eliminate 
vertical stripes; adjust the 
Sync setting to increase the sharpness.
The colors of the image are not right.

settings on the Image menu. See page 53.
■Make sure the input signal setting on the Signal menu matches 
the signal from the connected device. See page 54 for details.
If the image is too purple and you’ve connected a computer or 
RGB video device to the 
Computer1 or Computer2 port, select 
Computer as the input source. If you’ve connected a component 
video device to one of these ports, select 
Component Video. 
If you’re projecting from a composite video or S-Video source, 
select the correct 
Video Signal is selected on the Signal menu. 
■Check your computer display settings to correct the color balance.
■If the image seems dark, the lamp may be nearing time for 
replacement. Check the lamp hours as described on page 61 and 
replace it, if necessary, as described on page 74.

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 you are within 20 feet of the projector, and within

especially fluorescent lights, may affect the projector’s infrared 
receivers. If you still have trouble using the remote control, disable 
one of the remote receivers using the Settings menu to block 
interference from bright light. See page 56 for details.
■Turn off any nearby equipment that emits infrared energy, such 
as a radiant room heater.
