Troubleshooting
Problem: Nothing on projection screen
Make sure that the power cord is properly connected to a fully 
functional AC electrical outlet. Make sure that the power cord 
is also properly connected to the projector.
If the projector is plugged into a power strip, make sure the 
power strip is turned on.
Make sure you have removed the lens cap on the projection 
lens at the front of the projector.
Make sure the lamp is switched on.
Check the projector ’s lamp to ensure that it is securely con-
nected in the lamp module. See “Replacing the Projection 
Lamp” on page 29.
Make sure that the cables do not have any bent pins.
Problem: Color or text not being projected
You might need to adjust the brightness up or down until the 
text is visible. Refer to “Brightness” on page 19 for more infor-
mation.
Problem: The screen resolution is not right
Make sure the computer ’s video card is set for a resolution of 
no greater than 1024x768. 
Problem: Image isn’t centered on the screen
Move the projector to reposition the image.
Reposition the image using the software. Refer to “Horizontal 
position” on page 23 and “Vertical position” on page 23.
Be sure the projector is at a 90 degree angle to the screen.
Problem: Only the start-up screen displays
Verify that the cables are connected correctly. See page 7 
through page 8 for connection procedures.
Verify that the proper input source is connected. See “Source 
(keypad only) or Computer and Video (remote only)” on 
page 16.

Maintenance & Troubleshooting

You might need to turn everything off and power up the 
equipment again in the proper order. Refer to your com-
puter ’s documentation to determine the correct order.
Make sure your laptop’s external video port is turned on. See 
the “Portable and Laptop Activation Chart” on page 40 or 
your computer ’s manual for details.
Make sure your computer ’s video board is installed and con-
figured correctly.
Make sure your computer has a compatible video board. The 
projector isn’t CGA, EGA or SXGA compatible.
If you’re using Windows 98:
1Open “My Computer” icon, the Control Panel folder and 
then the Display icon.
2Click the Settings tab.
3Verify that the Desktop area is set to 1024x768 or less.
Problem: Image is too wide or narrow for screen
Adjust the zoom or projector placement.
Adjust the resolution of your video card if it’s greater than 
1024x768. 
						

							35

Turn the projection lens to focus the image.
Make sure the projection screen is at least 5 feet (1.5 m) from 
the projector.
Check the projection lens to see if it needs cleaning.
Problem: Image and menus are reversed left to right
Rear projection mode is probably turned on. Turn Rear Projec-
tion off in the Controls menu. The image should immediately 
return to forward projection. See “Rear Projection” on 
page 24.
Problem: the projector displays vertical lines, “bleeding” or 
spots
Adjust the brightness. See “Brightness” on page 19.
Check the projection lens to see if it needs cleaning.

2Tu r n  
Auto Image off and then back on again. See “Auto 
Image” on page 21. 
3Tu r n  
Auto Image off and adjust the synchronization and track-
ing manually to find an optimal setting. See “Manual Sync” 
on page 22 and “Manual Tracking” on page 22.
The problem could be with your computer ’s video card. If 
possible, connect a different computer.

Maintenance & Troubleshooting
Problem: Projected colors don’t match the computer or video 
player’s colors
Just as there are differences in the displays of different moni-
tors, there are often differences between the computer image 
and the projected image. Adjust the brightness, tint and/or 
contrast from the Display menu. See “Brightness” on page 19, 
“Tint” on page 19 and “Contrast” on page 19. 
Problem: Lamp seems to be getting dimmer
The lamp begins to lose brightness when it has been in use for 
a long time. Replace the lamp as described in “Replacing the 
Projection Lamp” on page 29.
Problem: Lamp shuts off
A minor power surge may cause the lamp to shut off. Unplug 
the projector, wait at least a minute, then plug it back in.
Make sure the vents are not blocked.

Portable and Laptop Activation Chart
NOTE: Visit our website at
www.infocus.com for the most
current activation chart. It is
located in the Technical Library in
the Service and Support section.
Many laptop computers do not automatically turn on their exter-
nal video port when a projector is connected. Activation com-
mands for some laptop computers are listed in the following 
table. (If your computer is not listed or the given command does 
not work, refer to the computer ’s documentation for the appro-
priate command.) On many laptops, the activation function key 
is labeled with an icon, for example   or the text CRT/LCD.
NOTE: Usually, pressing the key
commands once activates the
external video port, pressing it
again activates both the external
and internal ports, and pressing it
a third time activates the internal
port. Refer to your computer’s
documentation for details on your
specific model.
