Cleaning and Replacing the Air Filters
Clean the air filters on the bottom of the projector 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. 
To clean the air filters, follow these steps:
1. Turn off the projector and unplug the power cord.
2. To clean the filters, EPSON recommends using a small vacuum 
cleaner designed for computers and other office equipment. If you 
don’t have one, gently clean the filters with a soft brush (such as 
an artist’s paintbrush).
3. If the dirt is difficult to remove or a filter is broken, replace the 
filters as described on the next page. Contact your dealer or call 
EPSON at (800) 873-7766 in the United States to obtain new 
ones. In Canada, please call (800) 463-7766 for dealer referral.
note
When you get a replacement 
lamp for your projector, new 
air filters are included. You 
should replace the filters 
when you replace the lamp. 
						

							102Maintaining the Projector
Replacing the Filters
1. Turn the projector over (unless it’s ceiling-mounted). 
2. Remove the filters from the projector by sliding them out to the

3. Remove each filter from its holder by releasing the two tabs, as 
shown.
4. Install new filters in the holders, aligning the tabs with the slots on 
each side. 
5. Slide the assembled filters back into the projector.

Replacing the Lamp
The projection lamp lasts up to 7000 hours. (Lamp life results will 
vary depending upon environmental conditions and usage.) Turn the 
projector off when not in use. Continuous 24-hour-a-day use may 
reduce the overall life of this product. 
When the lamp nears the end of its life (as determined from projector 
usage), the message 
LAMP REPLACE appears on the screen and the 
lamp warning light   flashes orange. To maintain projector 
brightness and image quality, replace the lamp as soon as possible.
It is also time to replace the lamp when: 
■The projected image gets darker or starts to deteriorate.
■The lamp warning light   flashes red (the lamp is burnt out).
Contact your dealer or call EPSON at (800) 873-7766 in the United 
States for a replacement lamp. Request part number 
V13H010L26.
In Canada, please call (800) 463-7766 for dealer referral.
Follow these steps to replace the lamp:
1. Turn off the projector.
2. When the power light stops flashing, unplug the power cord.
3. Let the projector cool for at least half an hour (if it has been on). 
The lamp is extremely hot immediately after use. 
4. If the projector is mounted on the ceiling, remove the rear cover. 
note
You can check how long 
the lamp has been in use 
(see page 105).
warning
Let the lamp cool fully 
before replacing it. 
In the unlikely event that 
the lamp has broken, small 
glass fragments may be 
present and should be 
removed carefully to avoid 
injury.

							106Maintaining the Projector
Transporting the Projector
The projector is heavy and contains many glass and precision parts. 
Follow these guidelines to prevent injury or damage:
■When hand-carrying the projector, you should use the handle to 
lift it only a short distance (for example, to set it on a table). To 
move the projector over longer distances, place it on a rolling cart 
or use a dolly. 
■When shipping the projector for repairs, use the original 
packaging material if possible. If you do not have the original 
packaging, use equivalent materials.
■When transporting the projector a long distance, first place it in a 
hard-shell shipping case, and then pack it in a firm box, placing 
cushioning around the case. (An optional shipping case is 
available from EPSON; see page 14.)
■It’s a good idea to turn off the remote 
control before packing it in a carrying case. 
This prevents the batteries from discharging 
if something presses against one of the 
buttons. 
warning
The projector is heavy 
(approximately 25 lb). Use 
care when handling it to 
prevent physical strain or 
injury.

Solving Problems
This chapter helps you solve problems with your projector, and tells 
you how to contact technical support for problems you can’t solve 
yourself. 
If the projector is not working correctly, first look at its status lights 
and check for possible solutions on page 108. If you’re having a 
problem with the image or sound, see page 112; for the remote 
control, see page 117.
This chapter covers the following:
■Checking the projector’s status lights
■Solving problems with the image or sound
■Solving problems with the remote control
■Contacting technical support
note
You can also get on-screen 
help by pressing the blue 
?Help button on the 
projector or remote control. 
Follow the instructions on 
the screen. 
						

							108Solving Problems
Checking the Projector Status
If you’re having a problem with the projector, check the following: 
■Check the lights on the top of the projector (as described below). 
The lights can often tell you about the nature of the problem.
■You can also view the About menu screen (page 111). This gives 
you information about the lamp life and currently selected input 
signal. 
What To Do When the Lights Flash
The lights on top of the projector indicate the projector’s status and 
let you know when a problem occurs.
If the projector seems to be indicating a problem, locate the pattern of 
lights in the table on the next page, then follow the recommended 
solutions.

							Solving Problems109
Use this table to interpret the projector’s status lights, then follow the instructions provided:
Status lights   = on  = flashing  = off 
Light Description and solution
If no lights are on, make sure the power cord is connected securely both at the 
power outlet and the projector. If you have just replaced the lamp, make sure the 
cover is securely fastened
.
When the power light is orange, the projector is in sleep mode. Press the Power 
button to turn it on.
When the power light is flashing green, the projector is warming up. Wait for the 
image to appear.
When the power light is green, the projector is operating normally.
When the power light is flashing orange, the projector is cooling down. Do not 
unplug it until the light stops flashing and remains orange. If you want to turn it 
back on, wait until the light stops flashing.
When the power and temperature lights are flashing, the projector is getting too 
hot, but you can continue running it in this condition. 
Verify that the air filter is not clogged. Clean or replace it as described on page 101.
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.

When the power and temperature lights are red, the projector has overheated, 
which turns off the lamp automatically. Wait about 5 minutes for the projector to 
cool, then unplug the power cord. 
Verify that the air filter is not clogged. Clean or replace it as described on page 101.
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. Then plug the power cord 
back in and press the Power
 button. 
If the projector continues to overheat, contact EPSON for help (see page 118).
Warning: Except as specifically explained in this User’s Guide, do not attempt to 
service this product yourself.
When the power light is red and the temperature light is flashing red, there is a 
problem with the fan or temperature sensor. Unplug the power cord and contact 
EPSON for help (see page 118).
When the power light is green and the lamp light is flashing orange, the lamp is 
near the end of its life. To ensure continued operation, you should replace it as 
soon as possible (see page 103).
When the power light is red and the lamp light is flashing red, the lamp has burned 
out. Replace it as described on page 103.
If these lights come on after replacing the lamp, make sure the lamp is fully 
inserted and the lamp cover is attached. 
If all three lights are red, the projector has an internal problem. Unplug the power 
cord and contact EPSON for help (see page 118).
