Flashing 
orangeRapid 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 the projector for ventilation, and that 
the air filter and vents are clear. If you’re using the projector above 4900 
feet (1500 m), turn on 
High Altitude Mode; see page 75.
Red The projector is overheating, whic h 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 
Ppower button. Make  sure the room 
temperature is not above 95 °F (35 °C), and there is plenty of space 
around the projector for ventilation. If you’re using the projector above 
4900 feet (1500 m), turn on  High Altitude Mode; see page 75.
The air filter or vent may be clogged.  Clean them or replace the air filter 
as described on page 79.
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 102.
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 80 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 80. 
The air filter or vent may be clogged.  Clean them or replace the air filter 
as described on page 79.
If this does not resolve the problem, contact Epson as described on 
page 102.

■Enable the Auto Keystone feature to automatically fix the shape. 
See page 68. 
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. Use a 
distribution amplifier for longer distances; you can purchase one 
from Epson (see page 13).
■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 67).

■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.
■Make sure the projector is facing the screen squarely, to eliminate 
the need for keystone correction.
■Adjust the Sharpness setting on the Image menu (see page 65). 
When you change video settings, you should be able to see the 
effect on the screen immediately. If you’re projecting from a 
computer, you may also need to adjust the tracking and sync as 
described in the next section. If  you don’t like the new settings, 
you can always select 
Reset to return to the factory default 
settings.
You see vertical bands or the image still looks blurry after 
trying the solutions in  the previous section.
■If you’re projecting from a comput er and displaying an image that 
contains a lot of fine detail, you may notice vertical bands or some 
of the characters may look heavy or blurred. Press the 
Auto 
button on the remote control to reset the projector’s tracking and 
sync settings.
■If further adjustment is needed, you can fine-tune the Tracking 
and 
Sync settings manually using th e Signal menu, as described
