There is no sound.
■Try turning up the volume in the Audio menu (see page 51). 
■Make sure the A/V Mute function is not on.
■If you’re using a VCR 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 20 or 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 20.
■Make sure the Windows volume controls on your computer are 
not turned all the way down or set to Mute. Check this by 
clicking the volume control in your Windows System Tray (lower 
right corner of the screen). 
■The wrong source may be selected. Press the Source button on 
the projector—or the 
Computer1/2 or S-Video/Video button 
on the remote control—to select the correct source.
■Check the Audio Input setting in the Audio menu. 
						

							82Solving Problems
Solving Password Problems 
You have forgotten the password.
■Write down the request code that appears in the Password Protect 
Release screen and contact EPSON. See “Where To Get Help” 
on page 83.
■If you turned on the password protect feature before setting the 
password and no password was set before, try using the default 
password: 
0000.
You don’t have the remote control.
You must have the remote control to enter the password. If necessary, 
you can purchase a replacement remote control from EPSON (part 
number: V12H007T13).
Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.
■Make sure the tape has been removed from the battery tray as 
described on page 40. 
■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).
■The remote control battery may not be installed correctly or may 
be low on power. Change the battery as described on page 44.
■Dim the room lights and turn off any fluorescents. 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. 
						

							Solving Problems83
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 (part number 
V12H007T13).
To prevent losing the remote control, store it in the compartment 
beneath the projector, as described on page 40.
You can’t control the mouse pointer with the remote 
control.
■Make sure the mouse cable is securely connected to both your 
computer’s mouse port or USB port and the projector’s USB 
port. For details, see page 19.
■Make sure RS232C is selected as the COM Port setting in the 
Advanced menu. See page 54. 
■To use the USB mouse connection on a PC, your system must 
have a “clean” installation of Windows 98, Windows Me, 
Windows XP, or Windows 2000. The connection may not work 
correctly if your system was upgraded from Windows 95.

Compatible Video Formats
The projector supports NTSC, PAL, and SECAM international video 
standards, as well as the monitor and HDTV display formats listed 
below.
To project images output from a computer, the computer’s video card 
must be set at a refresh rate (vertical frequency) that’s compatible with 
the projector; see the following table for compatible formats. As noted 
below, some images are automatically resized to display in one of the 
projector’s “native” formats (such as XGA). In addition, the 
frequencies of some computers may not allow images to display 
correctly; see your computer’s documentation for details.
