The projector is overheating and 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.
The lamp status light is flashing red and the lamp does not come on.
Turn off the projector and turn it back on again. Check the lamp fight again.
If the lamp still does not come on, it may have burned out or become damaged.

6 l Troubleshooting 
						

							Problems with the Image or SoundIAn image does not appear on the screen.
Check that the power light is on and the lens cover is off. Also make sure the
Y-cable is installed correctly to both the image source and projector as described
in Chapter 1.
The projector may be in standby mode. Press the Standby button on the remote
control or operation panel to turn on the lamp.
The correct image source may not be selected. Press the Video button on the
remote control or operation panel to choose the other image source.
The brightness level may not be set correctly, Use the Brightness button to adjust
the brightness level.I
Only part of the computer image is displayed.
Your monitor is set up for a resolution higher than 640 x 480, and the projector
is compressing the image. You need to choose a different monitor display setting.
In Windows, use Windows Setup in the Main program group. For a Macintosh,
choose Control Panels under the Apple menu and then Monitors; in the Monitors
screen, choose Options and make sure Macintosh Hi-Res Display or another
640 x 480 display is selected. For supported display settings, see Appendix A.
You may also need to modify existing presentation files if you created for them for
a different resolution. See your software manual for specific information,

IOnly the test pattern is displayed.
The input source has not been selected correctly. Press the Video button on the
remote control or operation panel to select the other image source.
The projector is not detecting the signal from the source. Check that the cable is
securely attached to both the source and projector If it is, the problem may be
with your presentation software.
The proper order was not followed when the projector and peripheral devices
were turned on. Turn off the projector and all devices in the reverse order shown
on page 20. Then turn everything back on in the proper order.I
The image or parts of the image are blurred or not in focus.
Turn the focus ring on the projector to see if this improves the image. Check also
that the projector is within the recommended distance 
according to the size of
the screen (see page 4). For the sharpest images, the projector must be perpen-
dicular to the screen and the projection surface must be flat.
Adjust the Brightness and Contrast settings on the Computer or Video menu. If
you’re viewing a computer image, also try adjusting the Sync setting on the
Computer menu.
There may be dirt or stains on the lens. Clean the lens as described in Chapter 5.
6 l Troubleshooting 
						

							IThe 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 Computer menu. If you’re
displaying video, adjust the Color and Tint settings. Check also that Invert in the
Display menu is not selected.
The video cable from your computer may not be properly attached. Check to see
that it is properly and securely attached to the connectors on both the projector
and image source.I
Text is not displayed correctly.
The software program you are using displays text at 720Pixel, but the projector
displays text at 640 Pixel. Use the Text setting in the Computer menu to compress
the text to 640 Pixel.I
There is no sound.
Check first 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. Press the Mute button on the remote control to make sure the mute
function is not on.
The wrong source is selected. Use the Video button on the remote control to
change the source. Also, check that the Audio Source setting in the Audio menu
is not set for a specific source.
The Fade setting might not be appropriate. Adjust this setting in the Audio menu.
Problems with the Image or Sound69 
						

							Problems with the Remote Control
70I
You programmed the buttons on the remote control to control the
computer, but pressing one or more buttons has no effect.
First make sure the RS-23X serial cable is properly and securely connected as
described in Chapter 1. Check that the Serial setting on the Options menu is on
and the ELP Remote Programmer is running on your computer.
The remote control is more than 33 feet from the projector or is more than
30 degrees to the side of the projector. Move closer to the projector and hold the
remote control more directly in front of it.
There is an obstacle in the path between the remote control and the receiver at
the front or back of the projector. Remove anything blocking the path. If you’re
using rear projection and the screen is between the remote control and the
projector, you need to connect the remote control directly to the projector using
the optional lead wire.
Both the ELP Remote Programmer and ELP Link utilities are running. When both
are running, ELP Link has priority, You need to close ELP Link in order to use the
ELP Remote Programmer.
The ELP Remote Programmer might be set up for a different serial port than the
one you’re using. Bring up the ELP Remote Programmer and open the Special
menu to check which serial COM port is selected.6. Troubleshooting 
						

							The batteries in the remote control are not inserted properly or are no longer
good. Reinsert them or replace them if necessary.
A strong light source, such as direct sunlight or a compact fluorescent tube, is
causing interference. Move the projector away from the strong fight source.I
Using the trackball has no effect.
The remote control is in sleep mode. Press any button to exit sleep mode so you
can use the trackball.I
Double-clicking a programmable button has no effect.
You are double-clicking too fast and the projector is not able to distinguish both
clicks. Double-click more slowly.I
When using the ELP Remote Programmer on your PC, the mouse speed
is too slow or too East.
The ELP Remote Programmer mouse speed and the Windows Control Panel
mouse speed may be interfering with one another. First try adjusting the mouse
speed in the ELP Remote Programmer’s Special menu. If this does not solve the
problem, adjust the mouse speed in your computer’s Control Panel.
