Troubleshooting
Problem: Nothing on projection screen
•Make sure that the power cord is properly connected to a func-
tional 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 projector 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 25.
•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 17 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. A resolution of 800x600 yields the 
highest quality image.
Problem: Image isn’t centered on the screen
•Reposition the image. Refer to “Horiz. Position” on page 21 
and “Vert. Position” on page 21.
•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 9 for connection procedures.
•Verify that the proper input source is connected. See “Source” 
on page 15.

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 37 or 
your computer ’s manual for details.
•Make sure your computer ’s video board is installed and con-
figured correctly.
If you’re using Windows 3.x:
1In the Windows Program Manager, double-click the Win-
dows Setup icon in the Main program group.
2Verify that the Display setting is 1024x768 or less.
If you’re using Windows 95:
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.
 Also check the following: 
•Does your computer have a compatible video board? The pro-
jector isn’t CGA or EGA compatible.
•Is your computer ’s video port activated? This is especially 
true for laptop computers. See “Portable and Laptop Activa-
tion Chart” on page 37.
Problem: Image is too wide or narrow for screen
•You might need to manually adjust the tracking to reduce or 
enlarge the projected image. Refer to “Manual Tracking” on 
page 21.
•Adjust the resolution of your video card if it’s greater than 
1024x768 pixels.

•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 23.
Problem: the projector displays vertical lines, “bleeding” or 
spots
•Adjust the brightness. See “Brightness” on page 17.
•Check the projection lens to see if it needs cleaning.
Problem: no sound

2Tu r n  
Auto Image off and then back on again. See “Auto 
Image” on page 20. 
3Adjust the synchronization and tracking manually to find an 
optimal setting. See “Manual Sync” on page 21 and “Manual 
Tracking” on page 21.
•The problem could be with your computer ’s video card. If 
possible, connect a different computer. 
						

							32
Maintenance & Troubleshooting
Problem: Projected colors don’t match the computer or video 
player’s colors
•Adjust the brightness, tint and/or contrast from the Display 
menu. Just as there are differences in the displays of different 
monitors, there are often differences between the computer 
image and the projected image. See “Brightness” on page 17, 
“Tint” on page 17 and “Contrast” on page 17. 
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 25.
Problem: Lamp shuts off
•A minor power surge may cause the lamp to shut off. Turn the 
projector off, wait at least a minute, then turn it back on.

Portable and Laptop Activation Chart
Many laptop computers do not automatically turn on their exter-
nal video port when a secondary display device such as a projec-
tor is connected. Activation commands 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 com-
puter ’s documentation for the appropriate command.) On some 
laptops, the activation function key is labeled with an icon, for 
example   or the text CRT/LCD.
NOTE: Often, 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 
por t. Refer to your computer’s doc-
umentation for details on your spe-
cific model.
