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:

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 184 to diagnose the problem.  
						

							184Solving 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 filter 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 meters), 
turn on High Altitude Mode in the Operation menu (see page 149).
The air filter or vents may be clogged. Clean them or replace the air filter 
as described on pages 173 to 177.
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 197.
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. The air filter or 
vents may be clogged. Clean them or replace the air filter as described on 
pages 173 to 177.
If this does not resolve the problem, stop using the projector, disconnect 
the power cable, and contact Epson as described on page 197.
Flashing orange It’s time to replace the lamp. See page 174 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 174. 
The air filter or vents may be clogged. Clean them or replace the air filter 
as described on pages 173 to 177.
If this does not resolve the problem, contact Epson as described on 
page 197.
