qThe temperature indicator 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 nothing is blocking the 
ventilation vents.
The air filter may be clogged. Clean it as described in 
Chapter 5 and then let the projector cool for a while.
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 a qualified service person.

Warning: Do not attempt to service this product yourself except

Problems with the Image or Sound
qAn image does not appear on the screen.
Check that the power light is on and the lens cover is off. 
Also make sure the cables are installed correctly, as 
described in Chapter 1.
The correct image source may not be selected. Press the 
Source button on the remote control or the operation 
panel to choose another image source. 
qOnly part of the computer image is displayed.
If the computer’s output resolution setting is higher than 
1024 ´ 768 (EMP-7350/7250) and 800 ´ 600 (EMP-
5350), the projector resizes the image. If the computer 
output is not compatible with this resizing, choose a 
different display setting on the computer. In Windows 3.x, 
use Windows Setup in the Main program group. For a 
Macintosh, choose Control Panels under the Apple menu 
and then choose Monitors. In the Monitors screen, choose 
Options and make sure Macintosh Hi-Res Display or 
another 1024 ´ 768 (EMP-7350/7250) and 800 ´ 600 
(EMP-5350) display is selected. For supported display 
settings, see page “Supported Monitor Displays” on page 
97, 98.
You also may need to modify existing presentation files if 
you created them for a different resolution. See your 
software manual for specific information.
qThe message NO SIGNAL is displayed.
An image source not connected to the projector is selected, 
the signal is not being output from the computer, or the 
signal is not reaching the projector. Make sure the 
connectors are securely attached to both the projector and

the image source. Then check that the image source is 
selected correctly. When NO SIGNAL is displayed, you 
cannot access the Video (computer/video) menu.
qA blank screen is displayed.
The computer signal cannot be interpreted by the 
projector. Verify the display format (see page 97, 98). 
When you see a blank screen, you cannot access the 
projector menus.
qThe image or parts of the image are blurred or not 
in focus.
Adjust the Brightness and Contrast settings on the Video 
menu. If you’re viewing a computer image, also try 
adjusting the Tracking and Sync buttons on the projector’s 
operation panel. 
There may be dirt or smears on the lens. Clean the lens as 
described in Chapter 5, “Maintenance.”
qThe colors of the image are not right.
The color balance may be incorrect. If you’re displaying a 
computer image, adjust the red, green, and blue settings in 
the Video menu. If you’re displaying video, adjust the 
Color and Tint (NTSC only) settings on the Video menu.
qThere is no sound.
First check that the volume setting is not turned all the way 
down and that the audio/video cable is securely attached to 
both the projector and the audio source. Also, make sure 
that the Mute button is off.
The wrong source is selected. Press either the Computer or 
Video button on the remote control or operation panel to 
select the proper source.
