Checking Projector Status
If your projector isn’t working correctly, first turn it off and unplug it. 
Then plug the power cord back in and turn on the projector. If this 
doesn’t solve the problem, check the lights on top of the projector.
What To Do When the Lights Flash
The lights on top of the projector indicate the projector’s status.
Refer to the following tables for a complete description of the 
projector’s status lights:

Solving Projector Operation Problems
The power doesn’t turn on.
■If the projector doesn’t turn on when you press the Ppower 
button, make sure the power cord is connected to the projector 
and plugged into a working electrical outlet.
■The power cord may be defective. Disconnect the cord from the 
outlet and contact Epson as described on page 90.
■If you’re using the Direct Power On function and you 
immediately plug the power cord back in after unplugging it, the 
power may not turn back on. Press the Ppower button to turn 
the projector back on.
The buttons on the projector don’t work.
If the Control Panel Lock function has been enabled, you can’t use the 
buttons on the projector. Try using the remote control instead, or 
press and hold the projector’s 
Enter button for seven seconds to 
release the lock (see page 66).
Solving Problems With the Image 
or Sound
No image appears on the screen.
■Check that the Ppower light is green (not flashing) and that the 
A/V Mute slide is open. Also press the A/V Mute button on the 
remote control to make sure the picture has not been turned off 
temporarily.
■The projector may be in standby or sleep mode. If the Ppower 
light is orange, press the Ppower button to turn the projector on.
■If the power was switched off and then on again, the projector 
may be cooling down. Wait until the Ppower light stops flashing 
and remains orange; then press the Ppower button again.

■The attached computer may be in sleep mode or displaying a 
black screen saver. Try pressing a key on the computer.
■If you are projecting from a DVD player or other video source, 
make sure you turn it on and press its 
Play button.

message 
No Signal displayed.
■Make sure the cables are connected correctly, as described 
beginning on page 25.
■If you’ve connected a computer and one or more video sources, 
you may need to press the 
Source Search button to select the 
correct source. Allow a few seconds for the projector to sync up 
after pressing the button.
■Make sure the power for your connected equipment is turned on.
If you’re using a PC notebook: 
■Hold down the Fn key on the keyboard and press the function 
key that lets you display on an external monitor. It may have an 
icon such as  , or it may be labelled 
CRT/LCD. Allow a few 
seconds for the projector to sync up after pressing it. Check your 
notebook’s manual or online help for details. 
On most systems, the   key lets you toggle between the LCD 
screen and the projector, or display on both at the same time.
If you connect the notebook while the projector or computer are 
already turned on, the function 
Fn key that changes the 
computer’s image signal to external output may not work. Turn 
the computer and the projector off and then back on again.
■Depending on your computer’s video card, you might need to use 
the Display utility in the Control Panel to make sure that both the 
LCD screen and external monitor port are enabled. See your 
computer’s documentation or online help for details.

■If you’re projecting a widescreen computer image, adjust the 
Resolution setting (see page 57), if necessary.
■If you’re projecting an image from a computer with dual display 
activated, turn dual display off.
The image isn’t square, but keystone-shaped.
If the image isn’t evenly rectangular, adjust its shape as described on 
page 41.
The image contains static or noise.
■If you’re using a computer cable longer than 6 feet (1.8 meters), 
or an extension cable, the image quality may be reduced.
■Keep your computer and video cables away 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 notebook 
computer and the projector, turn off the notebook’s LCD display.
■Make sure the correct input signal is selected in the Signal menu 
(see page 58).
■If you’re using a composite, S-Video, or component video source 
with 480i signals, turn on the 
Progressive setting on the Signal 
menu (see page 58).

■If the projector is angled sharply toward the screen, it may not be 
possible to focus the entire image. Move the projector to position 
it more directly in front of the screen.
■Lower the projection angle to reduce the amount of keystone 
correction required.
■Make sure the projector is within the proper range (projection 
distance) from the screen (see page 19).
■Make sure the lens is not fogged by condensation. You may need 
to wait before using the projector after moving it from a cold 
environment to a warm environment.
■If you’re projecting from a computer, you may need to adjust the 
tracking and sync settings as described in the next section. 
You see vertical bands 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, you may notice vertical bands or some 
of the characters may look heavy or blurred. Press the 
Auto 
button on the remote control or the 
Enter button on the 
projector to reset the projector’s Tracking, Sync, and Position 
settings.
■If further adjustment is needed, you can fine-tune the Tracking 
and 
Sync settings manually using the Signal menu, as described 
on page 58.
1. Fill the screen with an image containing fine detail, such as a 
pattern to appear as your desktop background, or try 
projecting black text on a white background.
note
You must be projecting an 
image for the 
Auto button 
to have any effect. It works 
only with computer images 
projected through the 
Computer (Component 
Video) port.

Tracking to eliminate vertical bands. 
3. Adjust the 
Sync setting to increase the image sharpness. 
The image is too light or dark, or colors are incorrect.
■Press the Color Mode button or select a different Color Mode 
option in the Image menu. See page 44 for details on the available 
options.

Color Mode settings on the Image menu. You can also try 
adjusting the 
Color Saturation, Color Temp, and Tint settings 
on the Image menu.
■Try adjusting the Brightness and Contrast settings on the Image 
menu.

■Check your computer display settings to correct the color balance.
■The projector’s lamp may need to be replaced. See page 72 for 
instructions.
■Make sure the correct input signal is selected in the Signal menu

corner of the screen). On a Mac, you may be able to adjust the 
volume from your menu bar (top right corner of the screen) or via 
the volume control function keys.
■If you’re using a DVD player or other video source, make sure the 
cables are connected correctly, as described on page 34.
Nothing appears on an external monitor 
The only images that can be displayed on an external monitor are 
computer images connected through the 
Computer (Component 
Video) 
port (see page 33).
Solving Problems With the Remote 
Control
The projector doesn’t respond to remote control commands.
■Point the remote control towards the projector’s receiver. Make 
sure you are within 19.7 feet (6 meters) of the projector and 
within a 30° horizontal angle and a 15° vertical angle from the 
projector’s front or back receiver.
■The remote control’s batteries may not be installed correctly or 
may be low on power. To change the batteries, see page 76.

■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. Also, turn off any nearby equipment that emits infrared 
energy, such as a radiant room heater. 
■If any buttons are held for longer than 30 seconds, the remote 
enters sleep mode. Release any button that is held to wake the 
remote.
