■If you’ve turned off the picture and sound, press the A/V Mute 
button on the remote control to turn them on again.
■If you’re using a DVD player or other video source, make sure its 
volume is not turned all the way down or muted. Also, make sure 
the cables are connected correctly, as described in Chapter 1.
■Make sure the audio cable is connected to the correct Audio port. 
See page 23. 
■If your presentation includes computer audio, make sure the 
volume control on your computer is not turned all the way down 
or muted. Make sure the audio cable is securely connected to both 
the projector and your computer’s   headphone jack or
 audio out jack. See page 23.

Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.
■Make sure you are within 20 feet of the projector, and within 
range of the projector’s front or back sensor (approximately 30° to 
the left or right and 15° above or below).
■If a button on the remote control is held for more than 30 
seconds, the remote enters sleep mode. Press another button for 
normal operation. 
■The remote control batteries may not be installed correctly or may 
be low on power. Replace the batteries as described on page 49.
■Dim the room lights and turn off any fluorescent lights. 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 have lost the remote control.
You need the remote control to access many projector features. If you 
have lost it, you can order another from Epson. See page 94 for 
details.
The Page Up and Down buttons on the remote control don’t 
work.
■Make sure the USB mouse cable is securely connected to both 
your computer’s USB port and the projector’s USB port. For 
details, see page 21.
■Your computer must be connected to the Computer
(Component Video)
 port on the projector. 
						

							Solving Problems93
■If you’re running Windows 98SE or Me, you may need to install 
USB drivers from your Windows CD-ROM. After you install the 
drivers, restart both the computer and the projector to 
resynchronize the setup.

Compatible Computer Display Formats
You can connect the projector to a wide range of computers, including 
PCs and notebooks, Apple Macintosh, Power Macintosh series 
(including G3, G4 and G5 systems), PowerBook computers, many 
iMac and iBook series systems, and high-end workstations such as the 
Sun
® SPARCstation.™ 
Although images are displayed at the projector’s native resolution of 
800 × 600 pixels (PowerLite S5 Series) or 1024 × 768 pixels 
(PowerLite 77c). Epson’s patented SizeWise chip supports computer 
display formats ranging from VGA through SXGA+ (PowerLite S5 
Series) or UXGA (PowerLite 77c).
To project images output from a computer, the computer’s external 
monitor signal must be set at a refresh rate (vertical frequency) that’s 
compatible with the projector; see the following table for compatible 
formats. For best results, the computer’s resolution should be set to 
match the projector’s native resolution (1024 × 768, or 800 × 600). If 
this resolution isn’t available, select one of the other compatible 
formats:
■Windows:
Right-click the desktop, select 
Properties, click the Settings tab, 
and select a compatible resolution. (For a notebook displaying 
through an external monitor port, you’ll need to click the 
Advanced button on the Settings tab, then adjust the resolution 
of the external monitor.) 
■Macintosh OS X:
From the Apple menu, select 
System Preferences, then click 
Displays. Make sure the VGA Display or Color LCD dialog box 
is selected, then click the 
Display tab and select a compatible 
resolution. 
You may need to modify existing presentation files if you created them 
for a different resolution. See your software documentation for details.
