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 immediately. Discon-
nect all speaker cables and input sources, and leave the
AV receiver with its power cord disconnected for 1 hour.
After that, reconnect the power cord and set the volume
to maximum. If the AV receiver stays on, set the volume
to minimum, disconnect the power cord, and reconnect
your speakers and input sources. If the AV receiver turns
off when you set the volume to maximum, disconnect the
power cord, and contact the dealer from whom you pur-
chased this unit.
There’s no sound, or it’s very quiet
• Make sure that the digital input source is selected
properly (page 49).
• Make sure that all audio connecting plugs are pushed
in all the way (page 19).
• Make sure that the inputs and outputs of all compo-
nents are connected properly (page 27-40).
• Make sure that the polarity of the speaker cables is
correct, and that the bare wires are in contact with the
metal part of each speaker terminal (page 21).
• Make sure that the input source is properly selected
(page 57).
• Make sure that the speaker cables are not shorting.
• Check the digital audio output setting on the con-
nected device. On some game consoles, such as those
that support DVD, the default setting is off.
• If there’s no sound from a DVD player connected to an
HDMI IN, check the DVD player’s output settings,
and be sure to select a supported audio format.
• Check the volume. It can be set to
− ∞
dB,
−
81 dB
through +17, +18 dB (page 57). 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 59).
• While a pair of headphones is connected to the Phones
jack, no sound is output by the speakers (page 59).
• With some DVD-Video discs, you need to select an
audio output format from a menu.
• If your turntable uses an MC cartridge, you must con-
nect an MC head amp, or an MC transformer.
• Make sure that none of the connecting cables are bent,
twisted, or damaged.
• Not all listening modes use all speakers (page 82).
• Specify the speaker distances (page 91) and adjust the
individual speaker levels (page 92).
• Make sure that the speaker setup microphone is not
still connected.
• The input signal format is set to PCM or DTS. Set it to
Auto (page 108).
Only the front speakers produce sound
• When the Stereo listening mode is selected, only the
front speakers and subwoofer produce sound.
• In the Mono listening mode, only the front speakers
output sound if the Output Speaker setting is set to L/
R (page 96).
• Check the Speaker Configuration (page 88).
Only the center speaker produces sound
• If you use the Dolby Pro Logic IIx Movie, Dolby Pro
Logic IIx Music, or Dolby Pro Logic IIx Game listening
mode with a mono source, such as an AM radio station or
mono TV program, the sound is concentrated in the cen-
ter speaker.
• Make sure the speakers are configured correctly
(page 88).
The surround speakers produce no sound
• When the Stereo or Mono listening mode is selected,
the surround speakers produce no sound (page 82).
• 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 88).
