If there is no sound from 
the surround speakers,
check the following:
• Check all wires and con-
nections between receiver/
amplifier and speakers. Make
sure all wires are connected.
Make sure none of the
speaker wires are frayed,
cut, or punctured.
• Review proper operation of
your receiver/amplifier and its
surround-sound features.
• Make sure the movie or TV
show you are watching is
recorded in Dolby

If it is not, check to see if
your receiver/amplifier has
other surround modes you 
may use.
If there is no sound from 
the center speaker, check 
the following:
• Make sure that your 
receiver’s Center Channel 
Mode is in the “normal” or 
“wide” position. If it is in 
the “phantom” position, the
center speaker will not play.
• Check all connections
between processor/amplifier
and the center speaker.
If the system plays at low
volumes but shuts off as
volume is increased, check
the following:
• Check all wires and con-
nections between receiver/
amplifier and speakers. Make
sure all wires are connected.
Make sure none of the
speaker wires are frayed,
cut, or punctured.
• If more than one pair o f
