❏ Be sure that the mute and volume settings are correct on the source
device, such as a VCR, camcorder, or computer.
If no sound is coming out of an external sound system:

securely connected between the source device and the sound system. The
digital audio output from the projector functions only while playing the
internal DVD player.

cable connecting the projector to the sound system—either a digital
audio cable connected between digital audio ports, or a standard audio
cable connecting stereo audio ports.
❏ Press menu, go to Sound, and check that Mute is turned off. The volume
control does not affect the digital audio output and the stereo audio
output.

Interruption problems
If the projector stops responding to all controls:
❏ If possible, turn off the projector, then unplug the power cord and wait at
least 15 seconds before reconnecting power.

Wait a few minutes, then power on the projector.
❏ If a red warning light is on or blinking, see “Warning light problems” on
page 55.
