LEDs
The Lamp LED on top of the projector (Figure 13 on page 18) will 
alert you to certain problems. 
A solid red Lamp LED means it is time to change the lamp. 
See page 30.
A blinking red Lamp LED means the projector is overheat-
ing. Turn off the projector and allow it to cool.
The other LED on top of the projector indicates the normal oper-
ating state of the projector.
A solid green LED means the projector is on.
A blinking green LED means the projector does not recog-
nize an active source or is in DPMS mode. See page 24. 
A blinking orange LED means the projector is going into 
DPMS mode; a solid orange LED means the projector is in 
standby or DPMS mode. See page 24 for details.
Problem: The projector is not running
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 the projector is turned on. Verify that the LED is 
solid green.
Problem: Projector is running, but nothing appears on projec-
tion screen
Make sure you have removed the lens cap on the projection

Verify that the cables are connected correctly. See page 7 for 
connection procedures.
Make sure that the cables do not have any bent pins.
Verify that the proper input source is connected. See “Com-
puter and Video and Source/Select” on page 18.
Try resetting the projector. See page 22.
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 
your computer ’s manual for details.

figured correctly.

projector isn’t CGA or EGA 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 1280x1024 or less.

You might need to adjust the brightness up or down until the 
text is visible. Refer to “Brightness” on page 21 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 1280x1024.

Problem: Image is too wide or narrow for screen
Adjust the zoom or projector placement.
Adjust the width of the image. See page 23.
Problem: Image is out of focus
Turn the projection lens to focus the image.
Make sure the projection screen is at least 4.9 feet (1.5 m) from 
the projector, and that the projector is at a 90 degree angle to 
the screen.
Check the projection lens to see if it needs cleaning.
Problem: Projector does not respond to remote control
Check to see if the batteries in the remote control are viable.
Check to see if the batteries are inserted properly.

Check the audio input connections.
Adjust the projector ’s or audio source’s volume.
Verify that the projector ’s internal speaker is not set to mute. 
Problem: Image and menus are reversed left to right
Rear projection mode is probably turned on. Turn Rear off in 
the System menu. The image should immediately return to 
forward projection. See page 24.
Problem: Projected image is distorted
Try resetting the projector. See page 22.
Adjust the tuning of the image. See page 23.
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, color and/or 
contrast in the Main menu. See page 23. 
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 30.
