							Solving Problems85
See the information below for what to do when you see these warning 
lights or encounter other specific problems with the projector.
The   power light is flashing orange and you cannot turn 
on the projector.
The lamp is cooling down. Wait until the light turns off and then 
press the 
Power button to turn on the projector.
The   power light does not come on.
Press the Power button to turn off the projector, check that the 
power cable is connected securely both at the power outlet and the 
projector, and press the 
Power button again. Try removing and 
reseating the lamp.
Projected images get darker or start to deteriorate, or the 
 lamp warning light is flashing red.
Replace the lamp as described in Chapter 4.
The   temperature light is red.
nThe projector is overheating, which turns the lamp off 
automatically. Let the projector cool for a few minutes, then turn 
it back on. Make sure there is plenty of space around and under 
the projector for ventilation. If it continues to overheat, you may 
need to change the air filter.
nThe air filter may be clogged. Clean it as described in Chapter 4 
and then let the projector cool for awhile. If this does not work, 
you may need to change the air filter. See Chapter 4.
nIf the projector continues to overheat after you clean the air filter, 
the problem may be caused by damage to the cooling fan or 
internal circuits. Contact EPSON for help.
The   temperature light is flashing orange.
The projector is too hot. Press the Power button to turn it off and let

Problems with the Remote Control
The projector doesn’t respond to remote control commands.
nMake sure the remote control is turned on. 
nMake sure you are within 30 feet of the projector, and within 
range of the infrared receivers (approximately 30
° to left or right 
and 15
° above or below).
nThe remote control batteries may not be installed correctly or may 
be low on power. Check the installation or replace them as 
described on page 12.
nDim the room lights and turn off any fluorescents. Make sure the 
projector is not in direct sunlight. Strong lighting, especially 
fluorescent lights, may affect the projector’s infrared receivers.
nTurn off any nearby equipment that emits infrared energy, such 
as a radiant room heater.
You can’t control the mouse pointer with the remote 
control.
nMake sure the mouse cable is securely connected to both your 
computer’s mouse port (using the main cable) and the projector’s 
mouse port. See Chapter 1 for details.
nMake sure you have used the correct cable. The PS/2 mouse cable 
and Macintosh mouse cable look the same, but they are not 
identical. Check the label on the end of the cable.

Problems with the Image or Sound
No image appears on the screen.
nCheck that the power light is green, not flashing, and the lens 
cover is off. 
nThe projector may be in sleep mode. If the power light is orange, 
press the 
Power button to turn the projector on.
nIf the power was switched off and then on again, the projector 
may still be cooling down. Wait until the power light stops 
flashing and remains orange; then press the 
Power button again.
nMake sure the Brightness setting on the Video menu is correct. 
See page 64 for more information. Try selecting the 
Reset All 
setting to return all setup menus to their default values. 
nPress the A/V Mute button to make sure the picture has not been 
turned off temporarily. 
nThe attached computer may be in sleep mode or displaying a 
black screen saver. Try pressing a key on the computer.
You see a blue screen with the message No Signal
 
displayed.
nMake sure the cables are connected correctly, as described in 
Chapter 1.
nTry restarting your computer.
nIf you’ve connected more than one computer and/or video source, 
you may need to press the 
Computer or Video button (on the 
control panel) or the 
Comp1, Comp2/YCbCr, or Video button 
(on the remote control) to select the correct source. Allow a few 
seconds for the projector to sync up after pressing the button.
nIf you’ve connected a second computer or you’re using 
component video, make sure the 
BNC option in the Setting menu 
is correct. See page 69 for more information.
nMake sure the Computer 1/DVI selector switch on the projector’s 
interface panel is set correctly. See Chapter 1. 
						

							88Solving ProblemsIf you’re using a PC laptop:
nPress the function key that lets you display on an external 
monitor. It’s often labelled with an icon such as   but it may 
also be labelled 
CRT/LCD. You may have to hold down the Fn key 
while pressing it. Check your laptop’s manual or online help for 
details. 
On most systems, the   or 
CRT/LCD key lets you toggle 
between the LCD screen and the projector, or to display on both 
at the same time. Allow a few seconds for the projector to sync up 
after pressing it. 
nDepending 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 or online help for details.
If you’re using a PowerBook:
1. From the Apple menu, select 
Control Panels, then click 
Monitors and Sound.
2. Click the Arrange icon.
3. Drag one monitor icon on top of the other. This lets you 
display on the projector screen as well as the LCD screen.
4. If this option isn’t available, click the 
Monitor icon. 
5. Select one of the listed 
Simulscan resolutions. (Allow a few 
seconds for the projector to sync up after making the 
selection.)
The message Not Supported
 is displayed.
Make sure your computer’s resolution doesn’t exceed UXGA 
(1600 
´ 1200), and the frequency is supported by the projector 
(see page 95). If necessary, change your computer’s resolution setting 
as described below.  
						

							Solving Problems89
Only part of the computer image is displayed.
nPress the Resize button on the control panel or remote control.
nMake sure the image Position setting is correct on the Video 
menu. See page 64 for more information.
nIf the right or left side of the image is cut off, you may need to 
adjust the tracking using the buttons on the control panel. Hold 
down the + or – 
Tracking button to change the setting until the 
image looks correct.
nMake sure your computer’s resolution setting is correct. Ideally, it 
should be 1024 
´ 768 (PowerLite 8100i) or 1280 ´ 1024 
(PowerLite 9100i) to match the projector’s native resolution. If 
this option isn’t available, select one of the other compatible video 
formats listed on page 95. 
nWindows:
Right-click the desktop, select 
Properties, click the Settings 
tab, and use the dialog box to select a different resolution. 
nMacintosh:
On the Apple menu, choose 
Control Panels, then click 
Monitors and Sound. Select a different resolution. 
nYou also may need to modify existing presentation files if you 
created them for a different resolution. See your software manual 
for specific information.
The image has a distorted, crooked, or keystone (trapezoid) 
shape.
nThis may be caused by extending the legs and tilting the projector 
to position the image. Press the right 
+ or left – side of the 
Keystone button on top of the projector. Press and hold either 
side of the button until the image is rectangular.
nMake sure the projector faces the screen squarely. If the projector 
is not pointed straight at the screen, your image will be distorted. 
						

							90Solving Problems
The image or parts of the image are blurred or not in focus.
nAdjust the focus using the focus ring.
nAdjust the Brightness, Contrast, Sharpness, and Gamma settings 
on the Video menu. If you’re viewing a computer image, also try 
adjusting the 
Tracking and Sync buttons on the projector’s 
control panel.
When you change video settings, you should be able to see the 
effect on the screen immediately. If you don’t like the new 
settings, you can always select 
Reset to return to the factory 
default settings. 
nTry pressing the Auto button on the remote control or the Enter 
button on the control panel to automatically reset the video 
settings.
nThere may be dirt or smears on the lens. Clean the lens as 
described on page 77.
The image vibrates, flickers, or has vertical lines.
If you’re projecting from a computer, try pressing Auto on the remote 
control or 
Enter on the control panel. This resets the computer 
display settings automatically.
If that doesn’t work, adjust the 
Tracking and Sync using the buttons 
on the control panel. Hold down the button to change the setting 
until your image looks correct. It is best to project a gray screen (or the 
screen you see when you exit Windows) when you adjust these 
settings. 
You can also change the Tracking and Sync settings through the 
Video menu (see page 64). 
The image quality is poor on a laptop computer.
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 laptop computer and the 
projector, turn off the laptop LCD display.
note
Images will be projected more 
vividly if you adjust the 
Tracking before the Sync. 
						

							Solving Problems91
The colors of the image are not right.
nThe color balance may be incorrect. If you’re displaying a 
computer image, use the Gamma option in the projector’s Video 
menu to adjust the balance of red, green, and blue. If you’re 
displaying video, adjust the Color, Tint, and Gamma settings on 
the Video menu. Also try adjusting the Color Setting option in 
the Advanced menu.
nCheck your computer display settings to correct the color balance.
There is no sound.
nFirst check that the volume is not turned all the way down and 
that the audio cable is securely attached to both the projector and 
the audio source.
nMake sure the A/V Mute button is not enabled.
nIf you’re using a VCR or other video source, make sure the 
volume is not turned all the way down. Also, make sure the cables 
are connected correctly, as described in Chapter 1.
nIf your presentation includes computer audio, make sure the 
volume control on your computer is not turned all the way down. 
Make sure the audio cable is securely connected to both the 
projector and your computer’s   headphone jack or   audio 
out jack. See Chapter 1 for more information.
nMake sure the volume controls on your computer are not turned 
all the way down or set to Mute. 
nThe wrong source may be selected. Press the Computer or Video 
button on the control panel—or the 
Comp1, Comp2/YCbCr or 
Video button on the remote control—to select the proper source.
