Cleaning the Air Filter and Vent
Clean the air filter and air intake vent after every 100 hours of use. If 
they are not cleaned periodically, they can become clogged with dust, 
preventing proper ventilation. This can cause overheating and damage 
the projector. 
Follow these steps:
1. Turn off the projector. Wait for the 
Power light to stop flashing, 
then unplug the power cord.
2. Turn the projector upside down.
3. To clean the intake vent and filter, use a small vacuum cleaner 
designed for computers and other office equipment. If you don’t 
have one, gently clean the vent with a soft brush (such as an 
artist’s paintbrush).
4. If the dirt is difficult to remove or the filter is broken, replace the 
filter as described on page 144. Contact your dealer or call Epson 
at 800-GO-EPSON (800-463-7766) to obtain a new filter. 
note
To order replacement air 
filters, request part number 
V13H13408. See page 13 
for ordering information.

Replacing the Lamp and Air Filter
The life span of the projection lamp is about 2000 hours if 
Brightness Control in the Setting menu is set to High (default), and 
3000 hours if 
Brightness Control is set to Low. 
It is time to replace the lamp when: 
■The projected image gets darker or starts to deteriorate.
■The message Replace the lamp appears on the screen when the 
lamp comes on and the lamp warning light   flashes orange. To 
maintain projector brightness and image quality, replace the lamp 
as soon as possible. 
■The lamp warning light   flashes red (the lamp is burnt out).
Contact your dealer or call Epson at 800-GO-EPSON 
(800-463-7766). Request part number V13H010L38. 
Follow these steps to replace the lamp and air filter:
1. Turn off the projector.

In the unlikely event that 
the lamp has broken, small 
glass fragments may be 
present and should be 
removed carefully to avoid 
injury.
If the lamp is used after the 
replacement period has 
passed, the possibility that 
the lamp may break 
increases. When a lamp

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 13.)
■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 150 to diagnose the problem.  
						

							150Solving 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 162.
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 141.
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 162.
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 142 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 142. If this does not resolve the 
problem, contact Epson as described on page 162.
Flashing red Power is cut off because of an internal problem. Unplug the power cord 
and contact Epson for help, as described on page 162.
