Problem Solving
This section explains how to interpret the projector’s status lights, solve problems with the 
picture and remote control, and contact technical support.
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 isn’t working correctly, first turn 
it off, let it cool, and unplug it. Then plug the 
power cord back in and turn on the projector. If 
this doesn’t solve the problem, check the status 
lights on top of the projector.
The P power light is orange.
The projector is in sleep mode. Unplug it or press the P Power button to turn it on.
The P power light is flashing green.
The projector is warming up. Wait for the picture to appear.
The P power light is flashing orange and you can’t turn on the projector.
The lamp is cooling down. Wait until the light stops flashing, then press the P Power 
button.
The P power light does not come on.
Make sure the power cord is connected securely both at the power outlet and the projector.

The  warning light is flashing orange.
High-speed cooling is in process. If the projector gets too hot again, projection stops 
automatically. Make sure there is plenty of space around and under the projector for 
ventilation. Clean or replace the air filters if necessary (see page 26). If you are using the 
projector at an altitude above 5000 feet (1500 meters), switch the 
Fan Speed setting to High 
(see page 22).
The  warning light is red.
The projector is too hot and has turned itself off. Let it cool for five minutes, then turn it back 
on. Make sure there is plenty of space around and under the projector for ventilation. Clean 
or replace the air filters if necessary (see page 26). If you are using the projector at an altitude 
above 5000 feet (1500 meters), switch the 
Fan Speed setting to High (see page 22).
The  warning light is flashing red at half second intervals.
The lamp needs to be replaced. See page 27. 
The  warning light is flashing red at one second intervals.
■The lamp cover may be loose or off. Make sure it’s securely fastened. See page 28.
■There is an internal problem. Unplug the projector and contact Epson. See page 38.
Solving Projector Problems
The projector doesn’t turn on.
■Check the P power light. If it’s dark, the projector is not receiving power. Make sure the 
power cord is securely attached at both ends. Check that the electrical outlet isn’t 
controlled by a timer, wall switch, or power strip switch, which may be interrupting the 
power.
■If the P power light is orange, the projector is in sleep mode. Press the PPower button 
to turn on the projector.
If the Child Lock is being used (see page 22), you have to press and hold the projector’s 
P
Power button for at least 3 seconds to turn on the projector. (The remote control, 
however, operates normally.)
■If the P power light is green and not flashing, the projector is operating normally. Make 
sure the lens cover is off. Press the 
A/V Mute button on the remote control to make sure 
the picture hasn’t been turned off temporarily. 
						

							Problem Solving33
The projector turns itself off after a period of time.
The projector’s Sleep Mode function may be turned on. This causes the projector to turn 
itself off if it hasn’t received any input signals for a specified period of time. You can turn the 
Sleep Mode setting off. See page 22.
The projector turns on by itself.
If you are using the Direct Power ON feature, the projector turns on automatically when you 
plug it into an electrical outlet (see page 22). It may also turn itself on after power outages, or 
after any temporary interruption of power. Make sure your electrical outlet isn’t controlled by 
a wall switch or timer.
There is no sound coming from the projector.
■Make sure audio cables are connected to the Audio port, and your audio equipment is 
turned on.
■Use the   and   Volume buttons on the projector or remote control to adjust the 
sound output from the projector’s speaker.
■Press the A/V Mute button on the remote control to make sure the picture and sound 
haven’t been turned off temporarily.
The projector doesn’t respond to remote control commands.
■Make sure you’re within 20 feet of the projector, and within range of the projector’s front 
or back sensor (approximately 30° left or right, and 15° above or below).
■You may need to replace the remote control’s batteries. Make sure they’re inserted with 
the positive (+) ends facing the bottom of the remote, as shown on the Quick Setup sheet.
■Dim the room lights and turn off any fluorescent lights. Make sure the projector is not in 
direct sunlight.
■Turn off nearby equipment that emits infrared energy, such as a radiant room heater.

Solving Picture Problems
You see a screen with the message No Signal displayed.
■Make sure your video equipment is turned on.
■Make sure your cable(s) are connected correctly, as described in the Quick Setup sheet.
■Use the Source button(s) on the projector or remote control to select the correct input 
source. Allow a few seconds for the projector to sync up.
■Press the Menu button and select Info. Make sure the resolution or video signal format 
shown for your connected equipment is listed as a compatible format on page 41.
No picture appears on the screen.
■Make sure the projector is turned on (the P power light is green and not flashing). 
■Make sure the lens cover is off.
■Press the A/V Mute button on the remote control to make sure the picture hasn’t been 
turned off temporarily.
■If you’re projecting from a laptop, you may need to set it to display on an external 
monitor, as described below.
If you’re using a PC laptop:
Press the function key that lets you display on an external monitor. It’s often labeled with 
an icon such as  , but it may also be labeled 
CRT/LCD. You may have to hold down 
the 
Fn key while pressing it, or restart your laptop. Check your laptop’s manual or online 
help.
On most systems, the   key lets you toggle between the LCD screen and the 
projector, or display on both at the same time. Allow a few seconds for the projector to 
sync up after pressing it.
Depending on your computer’s video card, you might need to use the Display utility in 
the Control Panel to make sure that both the LCD screen and external monitor port are 
enabled. See your computer’s documentation for details.

The picture is upside-down or reversed.
Change the setting for the Projection option in the Settings menu. See page 20.
The image doesn’t fit on the screen correctly, or it is stretched or compressed.
■Press the Aspect button to select a different aspect ratio. See page 14.
■Check the Zoom Caption and Output Scaling settings. See pages 19 and 20.
■Use the Position setting in the Settings menu to reposition the image on the screen. See 
page 19.
The picture is wider at the top or bottom.
You’ve tilted the projector to raise or lower the image, causing it to become “keystoned.” Use 
the  or  
Keystone button on the projector or remote control to correct the problem.
Better yet, place the projector at a height approximately between the top and bottom of the 
screen, keeping it level, and then use the vertical lens shift dial to position the image (see 
page 13). You won’t have to correct for keystone distortion this way, and you’ll get a 
better-looking image.
The picture is taller on the left or right side.
The projector is set at an angle to the screen. Face it squarely toward the screen, and then use 
the horizontal lens shift dial to center the image. See pages 12 and 13.
The picture contains static or noise.
■Make sure your cable is securely connected at both ends.
■Excessive cable length may cause interference. The practical length of the cable depends 
on the type of cable used, its quality, and the complexity of your connections. Consider 
using a signal amplifier. 
■If you’re displaying the same image on your computer and projector screen, try turning 
off your laptop’s LCD display.
■Check the settings in the Video Signal and Input A options in the Settings menu to 
make sure they’re correct for your video equipment. See page 20.
■Make sure the Progressive setting is set to OFF when viewing video. If you notice 
flickering while viewing still images, switch the setting to 
ON. See page 19. 
						

							Problem Solving37
The picture is blurry.
■There may be dirt on the lens. Clean the lens as described on page 25.
■Make sure the lens is not fogged by condensation. If you’ve just moved the projector from 
a cold environment, wait a couple of minutes before using it.
■Adjust the focus using the focus ring. See page 13.
■Make sure the projector is placed the correct distance from the screen: no closer than 
2.4feet (73cm) and no farther than 45.7 feet (13.9 m). 
■Adjust the Sharpness setting in the Image menu. See page 18.
■If you’re using the Keystone adjustment, be aware that it lessens image quality. You may 
wish to decrease the projection angle to reduce the amount of keystone correction 
needed, or use the lens shift dials to position the image. See page 13.
■If you’re projecting from a computer, press the Auto button on the remote control. If 
you see no improvement, you may need to adjust the 
Tracking and Sync. See page 18.
The picture looks too light or too dark.
■Make sure the Setup Level is set correctly (see page 20). If it’s not, dark or black parts of 
the picture may look washed-out.
■Press the Color Mode button on the remote control to select the best setting for your 
viewing environment.
■Adjust the Brightness and Contrast settings in the Image menu. See page 18. 
Note: These settings should be adjusted separately for each video source you’re using.
■If the picture looks darker than it used to, you may need to replace the lamp. See page 27.
The colors on the screen don’t look right.
■Press the Color Mode button on the remote control to select the best setting for your 
viewing environment.
■Adjust the following settings in the Image menu: Color Saturation, Tint, Color Temp., 
and 
Skin Tone. See page 18. 
Note: These settings should be adjusted separately for each video source you’re using.
■Check the settings in the Video Signal and Input A options in the Settings menu to 
make sure they’re correct for your video equipment. See page 20.
■If your video equipment is connected with component video cables, make sure all three 
connectors are securely attached at both ends.
