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 table for a complete description of the 
projector’s status lights:
Temperature light
Lamp light
Power light
Status lights
Light Status Description
Orange The projector is in sleep or standby mode. You can unplug it or press the 
P power button to turn it on.
Flashing green The projector is warming up. Wait for the image to appear.
Green The projector is operating normally.
Flashing orange The projector is cooling down. You can’t turn it back on (and you should 
not unplug it) until the light stops flashing and remains orange.
The projector is setting itself up for network monitoring.
Red or 
flashing redThere is a problem with the projector. Check the other two lights and the 
information on page 84 to diagnose the problem.  
						

							84Solving Problems
Flashing orange It’s time to replace the lamp. See page 74 for instructions. If you continue 
to use the lamp after the replacement warning, there is an increased 
possibility that the lamp may break.
Flashing orange Rapid cooling is in progress. Although this is not an abnormal condition, 
projection will stop automatically if the temperature rises higher. Make 
sure there is plenty of space around and under the projector for 
ventilation, and that the air filter and vents are clear.
Red The projector is overheating, which turns the lamp off automatically. 
Wait until the projector switches to standby mode (about 5 minutes). 
Make sure the room temperature is not above 95 °F (35 °C), and there is 
plenty of space around and under the projector for ventilation. 
The air filter may be clogged. Clean or replace the air filter as described 
on pages 70 to 74.
If you’re using the projector above an altitude of 4,900 feet (1,500 
meters), turn on High Altitude Mode in the Operation menu (see 
page 60).
If the projector continues to overheat after you clean the air filter, the 
problem may be caused by damage to the cooling fan or temperature 
sensor. Contact Epson for help as described on page 93.
Warning: Except as specifically explained in this User’s Guide, do not 
attempt to service this product yourself.
Flashing red Power is cut off because of an internal problem. Unplug the power cord 
and contact Epson for help, as described on page 93.
Flashing red  There is a problem with the fan or temperature sensor. Stop using the 
projector, disconnect the power cord, and contact Epson as described on 
page 93.
Flashing red The lamp may be burnt out. First make sure the lamp cover is securely 
installed. If that’s not the problem, the air filter may be clogged. Clean or 
replace the air filter as described on pages 70 to 74.
If this does not resolve the problem, let the lamp cool and then remove it. 
If the lamp is cracked, replace it as described on page 74. If the lamp is 
not cracked, reinstall it. If reinstalling doesn’t work, replace the lamp.
If you’re using the projector above an altitude of 4,900 feet (1,500 
meters), turn on High Altitude Mode in the Operation menu (see 
page 60).
If none of these suggestions resolves the problem, contact Epson as 
described on page 93.

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 93.

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 (make 
sure it is set to the correct ID). See page 58 for information about the 
Control Panel Lock function.
Solving Problems With the Image

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.

							88Solving Problems
■You also may need to modify existing presentation files if you 
created them for a different resolution. See your software 
documentation for specific information.
■If you’re projecting a wide panel computer image, adjust the 
Resolution setting (see page 50).
■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 square or rectangular, adjust its shape as described on 
page 33.
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 51).
■If you’ve used the Quick Corner or Keystone adjustment, you 
may need to decrease the 
Sharpness setting in the Image menu 
(see page 49).
■If you’re projecting from a computer, make sure its signal is 
compatible with the projector. See page 101.
The image is blurry.
■There may be dirt or smears on the lens. Clean the lens as 
described on page 70.
■Adjust the focus using the focus ring (see page 32). 
						

							Solving Problems89
■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 99).
■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 51.
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.
2. Adjust the 
Tracking to eliminate vertical bands. 
note
You must be projecting an 
image for the 
Auto button 
to have any effect. It works 
only with computer images 
projected through the VGA 
port. 
						

							90Solving Problems3. Adjust the 
Sync setting to increase the image sharpness. 
The image is too light or dark, or colors are incorrect.
■Use the Color Mode option in the projector’s Image menu to 
adjust the color (see page 48).

Color Mode settings on the Image menu. You can also try 
adjusting the 
Color Saturation, ABS Color Temp, and Tint 
settings on the Image menu.

instructions.
■Make sure the correct input signal is selected in the Signal menu 
(see page 51).
■Make sure that all cables are connected to the proper ports and 
connected securely.
There is no sound, or the sound is not loud enough.
■In order to play sound, you must connect optional external 
speakers (see page 21).
