Problem Solution

from the speakers

amplifier.
(No sound comes
from the home theater
system speakers.)
The projector is not equipped with the speakers.
The AV amplifier reads the information that projector is not equipped with the speakers
and then passes this information along to the DVD player. Because of this, either the
DVD player may be temporarily stopping audio output, or the AV amplifier may be
temporarily stopping audio output from the DVD player.
Change the setting on the AV amplifier or the DVD player.
