Transporting the Projector
The projector contains many glass and precision parts. Follow these 
guidelines to prevent damage: 
■When shipping the projector for repairs, use the original 
packaging material if possible. If you do not have the original 
packaging, use equivalent materials, placing plenty of cushioning 
around the projector.
■When transporting the projector a long distance, first place it in a 
hard-shell shipping case, then pack it in a firm box with 
cushioning around the case. 
■Close the A/V mute slide (lens cover) to protect the lens.

							Solving Problems75
Checking Projector Status
If your projector isn’t working correctly, first turn it off, wait for it to 
cool (the 
Power light stops flashing orange), 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

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 until the light 
stops flashing and remains orange. 
Red There is a problem with the projector. Check the other two lights and the 
information on page 76 to diagnose the problem.  
						

							76Solving Problems
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 filters and vents are clear.
Red The projector is overheating, which turns the lamp off automatically. 
Wait until the cooling fan stops, then unplug the power cord. Plug the 
power cord back in and press the 
P Power button. 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. 
If you’re using the projector above an altitude of 5000 feet (1500 m), 
turn on High Altitude Mode in the Operation menu (see page 60).
The air filters may be clogged. Clean or replace them as described on 
page 65.
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 83.
Warning: Except as specifically explained in this User’s Guide, do not 
attempt to service this product yourself.
Flashing red  There is a problem with the fan or temperature sensor. Stop using the 
projector, disconnect the power cable, and contact Epson as described 
on page 83.
Flashing orange It’s time to replace the lamp. See page 66 for instructions. If you continue 
to use the lamp after the replacement warning, there is an increased 
possibility that the lamp may break.
Flashing red The lamp may be burnt out. First make sure the lamp cover is securely 
installed. If that’s not the problem, let the lamp cool, remove the lamp, 
and replace it as described on page 66. If this does not resolve the 
problem, contact Epson as described on page 83.
Flashing red Power is cut off because of an internal problem. Unplug the power cord 
and contact Epson for help, as described on page 83.

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 cable is connected to the projector 
and plugged into a working electrical outlet.
■The power cable may be defective. Disconnect the cable from the 
outlet and contact Epson as described on page 83.

The message Not Supported is displayed.
■Make sure the correct input signal is selected in the Signal menu 
(see page 52).
■Make sure your computer’s resolution doesn’t exceed UXGA 
(1600 
× 1200) and the frequency or refresh rate is supported by 
the projector (see page 91). If necessary, change your computer’s 
resolution setting. 
Only part of the computer image is displayed.
■Press the Auto button on the remote control.
■Make sure the image Position setting is correct in the Signal 
menu. See page 53 for more information.

function.
■Make sure your computer’s resolution setting is correct. Ideally, it 
should be 1024 
× 768 to match the projector’s native resolution. 
If this option isn’t available, select one of the other compatible 
video formats listed on page 91.
■You also may need to modify existing presentation files if you 
created them for a different resolution. See your software 
documentation for specific information.
The image isn’t square, but keystone-shaped.
■If the image isn’t square or rectangular, adjust its shape as 
described on page 22.
■Enable the Auto Keystone feature to automatically fix the shape 
when the projector is tilted upward. See page 54.  
						

							80Solving Problems
The image contains static or noise.
■If you’re using a computer cable longer than 6 feet, 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 53).
■If you’ve used the Quick Setup, Quick Corner, or Keystone 
adjustment, you may need to decrease the 
Sharpness setting in 
the Image menu (see page 51).
The image is blurry.
■There may be dirt or smears on the lens. Clean the lens as 
described on page 64.
■Adjust the focus using the focus ring (see page 22).
■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.
■Make sure the projector is within the proper range (projection 
distance) from the screen (see page 89).
■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 as described in the next section.
