							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, make sure the power 
cable is connected securely to the power outlet and the projector, and 
press the 
Power button again. Try removing and reseating the lamp.
The   power light is red and the projector is turned off.
Power to the projector has been shut off because of an internal 
problem. Unplug the projector and contact EPSON.
Projected images get darker or start to deteriorate, or the 
 lamp warning light is flashing red or orange.
The lamp is burned out or is nearing the end of its life and needs to be 
replaced. See Chapter 4 for instructions.
The   temperature light is red.

The 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.

The 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.

If 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 
it cool for 5 minutes before using it again.
The   temperature light is flashing red.
The cooling fan or temperature sensor is not working correctly and

Problems with the Remote Control
The projector doesn’t respond to remote control commands.

Make sure the remote control is turned on. 

Make sure you are within 30 feet of the projector, and within 
range of the infrared receivers (approximately 30
° to the left or 
right and 15
° above or below).

The 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.

Dim 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.

Turn 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.

Make 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.

Make 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.

The message Not Supported is displayed.
Make sure your computer’s resolution doesn’t exceed UXGA 
(1600 
× 1200) for the PowerLite 9100i or SXGA (1280 × 1024) for 
the PowerLite 8200i. Also make sure the frequency is supported by 
the projector. (See page 95.) If necessary, change your computer’s 
resolution setting as described below. 
Only part of the computer image is displayed.

Press the Resize button on the control panel or remote control.

Make sure the image Position setting is correct on the Video 
menu. See page 64 for more information.

If 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 until the image looks correct.

Make sure your computer’s resolution setting is correct. Ideally, it 
should be 1024 
× 768 (PowerLite 8200i) 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.

created them for a different resolution. See your software manual 
for specific information. 
						

							90Solving Problems
The image has a distorted, crooked, or keystone (trapezoid) 
shape.

This may be caused by extending the legs and tilting the projector 
to position the image. Press the right 
+ or left – side of the 
projector’s 
Keystone button until the image is rectangular.

Make sure the projector faces the screen squarely. If the projector 
is not pointed straight at the screen, your image will be distorted.
The image or parts of the image are blurred or not in focus.

Adjust the focus using the focus ring.

Adjust 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 control panel. 
When you change video settings, you should be able to see the 
effect on the screen immediately.

Try pressing Auto on the remote control or the Enter button on 
the control panel to automatically reset the video settings.

There 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 until your image looks correct. It is best to project a 
gray screen (or the Windows exit screen) 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
If you don’t like the new 
settings, you can always select 
Reset to return to the factory 
default settings. 
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 or the image is dark.

Try adjusting the brightness and contrast in the Video menu.

The color balance may be incorrect. If you’re displaying a 
computer image, use the Gamma option in the Video menu to 
adjust the balance of red, green, and blue. If you’re displaying 
video, adjust the Color, Tint, and Gamma settings. Also try 
adjusting the Color Setting option in the Advanced menu.

Make sure the RGB cable is connected correctly.

Try adjusting the Brightness and Contrast settings on the Video 
menu. (See page 64.)

Check your computer display settings to correct the color balance.

It may be time to replace the lamp. When the lamp is nearing the 
end of its life, the image will appear dark and start to deteriorate.
There is no sound.

First 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.

Make sure the A/V Mute button is not enabled.

If 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.

If your presentation includes computer audio, make sure the 
volume controls on your computer are not turned all the way 
down or set to Mute. Make sure the audio cable is securely 
connected to the projector and your computer’s   headphone 
jack or   audio out jack. 

The 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.
