Connecting to Video Sources
You can connect a DVD player, VCR, camcorder, laser disc player, 
gaming consoles, such as Microsoft Xbox, Sony PlayStation 2, and 
Nintendo GameCube, digital camera, or any other compatible video 
source to your projector.
The projector supports HDTV, NTSC, PAL, and SECAM, and 
automatically detects the video format.
The projector can receive composite video, S-Video, and component 
video. The type of cable you use depends on whether you have 
composite video, S-Video, or component video. 
■For composite video, use the included RCA AV cable included 
with the projector.
■For component video, you will need the optional EPSON 
component video cable (ELPKC19).
■For S-Video, use the S-Video cable supplied with your video 
device or obtain one from you electronics dealer.
Follow the instructions below for your type of connection.
note
The projector does not 
support TV antenna cable 
F connectors.
To play audio from your 
video equipment, you will 
need a special adapter cable. 
See your projector dealer to 
obtain the correct cable.

Turning On Your Equipment
Make sure your projector and other equipment are set up and 
connected correctly, as described in Chapter 1 or Appendix A. Then 
turn on your projector, as described below, followed by any 
equipment you’ve connected to it. You can turn on your computer 
and video equipment in any order, but if you have both a computer 
and video source connected, you may have to switch to the desired 
source as described on page 21. 
Turning On the Projector
Follow these steps to plug in and turn on the projector:
1. Connect one end of the power cord to the projector’s power inlet. 
2. Connect the other end to an electrical outlet. 
The power light on top of the projector turns orange, indicating 
that the projector is receiving power but not yet turned on.  
3. Remove the lens cap.
caution
Do not use the projector with 
the lens cap in place. The 
heat generated by the lens can 
damage the cap.

remote control. 
The power light flashes green as the projector warms up, and the 
projection lamp comes on in about 30 seconds. The power light 
stays green. 
5. Do one of the following:
■If you’re using a computer, turn it on or restart it. In a few 
moments, you should see your computer display projected. 
(Windows
® only: If you see a message saying that it has found 
a plug-and-play monitor, click 
Cancel.) 
■If you’re projecting a video, press the Source button on top 
of the projector to switch to your video source, and press the 
Play button on your DVD player or other device.
If a projected image fails to appear, see the next section for help. 
Once you see your image, turn to page 25 for instructions on focusing 
and making other image adjustments. 
When you’re done with your presentation, shut down the projector as 
described on page 28. Shutting down the projector correctly prevents 
premature lamp failure and possible damage from overheating.

What To Do If You See a Blank Screen
If you see a blank screen or a blue screen with the message No Signal 
after turning on your computer or video source, try the following:
■Make sure the cables are connected correctly, as described on

■Try restarting your computer.
■Press the Source button on top of the projector to select the 
correct source. (Allow a few seconds for the projector to sync up 
after pressing the button.)
If you’re using a PC laptop:
■Hold down the Fn key and press the function key that lets you 
display on an external monitor. It may have an icon such as   
or it may be labelled 
CRT/LCD. Allow a few seconds for the 
projector to sync up after 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 display on both at 
the same time. 
■Depending 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.
