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. (An optional case is available from 
Epson; see page 11.)
■Close the A/V Mute slide (lens cover) to protect the lens.

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 
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. 
Red There is a problem with the projector. Check the other two lights and the 
information on page 68 to diagnose the problem.  
						

							68Solving Problems
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 76.
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. 
The air filters may be clogged. Clean or replace them as described on 
page 59.
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 76.
Warning: Except as specifically explained in this User’s Guide, do not 
attempt to service this product yourself.
Flashing orange It’s time to replace the lamp. See page 60 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 60. If this does not resolve the 
problem, contact Epson as described on page 76.
Flashing red Power is cut off because of an internal problem. Unplug the power cord 
and contact Epson for help, as described on page 76.
