Troubleshooting
If you have any trouble using the AV receiver, look for a
solution in this section. If you can’t resolve the issue
yourself, contact the dealer from whom you purchased
this unit.
Can’t turn on the AV receiver?
• Make sure that the power cord is properly plugged into
the wall outlet.
• Unplug the power cord from the wall outlet, wait five
seconds or more, then plug it in again.
The AV receiver turns off as soon as it’s turned
on?
• The amp protection circuit has been activated.
Remove the power cord from the wall outlet immedi-
ately and contact the dealer from whom you purchased
this unit.
There’s no sound, or it’s very quiet?
• Make sure that all audio connecting plugs are pushed
in all the way (page 20).
• Make sure that the inputs and outputs of all compo-
nents are connected properly (page 20).
• Make sure that the polarity of the speaker cables is
correct, and that the bare wires are in contact with
metal part of each speaker terminal (page 22)
• Make sure that the input source is properly selected
(page 44).
• Make sure that the speaker cables are not shorting.
• Check the volume. It can be set to MIN, 1 through 99,
or MAX (page 44). The AV receiver is designed for
home theater enjoyment. It has a wide volume range,
allowing precise adjustment.
• If the MUTING indicator is shown on the display,
press the remote controller’s [Muting] button to
unmute the AV receiver (page 45).
• While a pair of headphones is connected to the Phones
jack, no sound is output by the speakers (page 45).
• Check the digital audio output setting on the con-
nected device. On some games consoles, such as those
that support DVD, the default setting is off.
• With some DVD-Video discs, you need to select an
audio output format from a menu.
• If your turntable doesn’t have a built-in phono preamp,
you must connect one between it and the AV receiver.
If your turntable uses an MC cartridge, you must con-
nect an MC head amp, or an MC transformer and
phono equalizer.
• Make sure that none of the connecting cables are bent,
twisted, or damaged.
• Not all listening modes use all speakers (page 51).
• Specify the speaker distances (page 41) and adjust the
individual speaker levels (page 42).
• Make sure that the speaker setup microphone is not
still connected.
Only the front speakers produce sound?
• When the Stereo listening mode is selected, only the
front speakers and subwoofer produce sound.
• When the Direct listening mode is selected, only the
front speakers produce sound.
• Make sure the speakers are configured correctly
(page 39).
Only the center speaker produces sound?
• If you use the Pro Logic II Movie or Pro Logic II
Music listening mode with a mono source, such as an
AM radio station or mono TV program, the sound is
concentrated in the center speaker.
• Make sure the speakers are configured correctly
(page 39).
The surround speakers produce no sound?
• When the Stereo or Direct, listening mode is selected,
the surround speakers produce no sound (page 51).
• Depending on the source and current listening mode,
not much sound may be produced by the surround
speakers. Try selecting another listening mode.
• Make sure the speakers are configured correctly
(page 39).
The center speaker produces no sound?
• When the Mono, Stereo, Direct, or Orchestra listening
mode is selected, the center speaker produces no
sound (page 51).
• Make sure the speakers are configured correctly
(page 39).
