• Check that receiver/amplifier is on and a source is playing.
• Check all wires and connections 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.
• Check the "Balance" control on your receiver/amplifier.
• Check all wires and connections between receiver/ amplifier and speakers. Make sure all wires are
connected. Make sure none of the speaker wires are frayed, cut or punctured.

speaker in question is enabled.
• In Dolby Digital or DTS mode, check the speaker and channel output levels and adjust if needed.
• Turn off all electronics and switch the speaker in question with one of the other speakers that
is working correctly. Turn everything back on, and determine whether the problem is in the

that was not working now sounds fine; or whether it has moved: i.e., the speaker that was
not working still has no sound and the speaker that was working is still fine. If the problem is in
the same place, the source of the problem is most likely with your receiver or amplifier, and you

followed the speaker, consult your dealer for further assistance or, if that is not possible,
