Checking Projector Status
If your projector isn’t working correctly, first turn it off, wait for it to 
cool (the projector beeps twice and the  Ppower 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.

134Solving 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 149.
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 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 117.
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 
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 117.
The air filter or vent may be clogged. Clean them or replace the air filter 
as described on page 121.
If the projector continues to overheat after you clean or replace the air 
filter, contact Epson for help as described on page 149.
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 122 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 check if it is cracked. If it is cracked, replace it as described on 
page 122. If it not cracked, reinstall the lamp and try using it again.
The air filter or vent may be clogged. Clean them or replace the air filter 
as described on page 121.

The Projector and Notebook Don’t Display the Same Image
If you’re projecting from a notebook, and you can’t see your image on 
the projection screen and on your computer at the same time, follow 
these guidelines.
If you’re using a PC notebook:
■On most systems, there’s a function key that lets you toggle 
between the LCD screen and the projector, or display on both at 
the same time. It may be labeled 
CRT/LCD or have an icon such as 
. You may have to hold down the 
Fn key while pressing it. 
Allow a few seconds for the projector to sync up after changing 
the setting.
■If the function key doesn’t permit  you to display simultaneously 
on both screens, you should check your monitor settings to make 
sure both the LCD screen and the external monitor port are 
enabled. 
From the Control Panel, open the 
Display utility, select the 
Settings option, then select the Advanced option (in Windows 
Vista, right-click on the desktop, select 
Personalize, select 
Display Settings, then select Advanced Settings).The method 
for adjusting the settings varies by brand; you may need to click a 
Monitor tab, then make sure the external Monitor port is set as 
your primary display and/or enabled. See your computer’s 
documentation or online help for details.
If you’re using Mac OS X:
You may need to set up your system to display on the projector screen 
as well as the LCD screen. Make sure your projector is connected and 
follow these steps:
1. Open 
System Preferences. 
2. Click 
Display or Displays.
