							Problems with the Projector

❑The 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 on 
page 59 in Chapter 4 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 
as specifically explained in this User’s Guide.

Problems with the Image or Sound
❑An 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 Source button 
on the appropriate input operation panel to choose another 
image source. 
❑Only part of the computer image is displayed.
If the computer’s output resolution setting is higher than 
1024 × 768 (EMP-713/703) and 800 x 600 (EMP-503), 
the projector resizes the image. If the computer output is 
not compatible with this resizing, choose a different display 
setting on the computer. For supported display settings, see  
“Supported Monitor Displays” on page 71, 72.
You also may need to modify existing presentation files if 
you created them for a different resolution. See your 
software manual for specific information.
❑The 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. 
						

							Problems with the Image or Sound

❑A blank screen is displayed.
The computer signal cannot be interpreted by the 
projector. Verify the display format (see page 71, 72). 
When you see a blank screen, you cannot access the 
projector menus.
❑The 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 4, “Maintenance.”
❑The 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.
❑There is no sound.
First check that the volume setting is not turned all the way 
down and that the RCA audio 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 Source button on 
the operation panel to select the proper source.

Supported Monitor Displays
The projector displays images at a resolution of 1024 x 768 
(EMP-713/703) and 800 x 600 (EMP-503) pixels.
To display a higher resolution image, the projector 
compresses it to 1024 x 768 (EMP-713/703) and 800 x 600 
(EMP-503). The following table lists the display formats 
supported by the projector:
