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.
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.
There’s no sound, or it’s very quiet
Make sure that the digital input source is selected
properly (page 44).
Make sure that all audio connecting plugs are pushed
in all the way (page 21).
Make sure that the inputs and outputs of all compo-
nents are connected properly (page 24-37).
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 17).
Make sure that the input source is properly selected
(page 54).
Make sure that the speaker cables are not shorting.
Check the volume. It can be set to
dB, 81.5 dB
through +18.0 dB (page 54). The AV receiver is
designed for home theater enjoyment. It has a wide
volume range, allowing precise adjustment.
While a pair of headphones is connected to the Phones
jack, no sound is output by the speakers (page 56).
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 digital audio output setting on the con-
nected device. On some game 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 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 86).
Specify the speaker distances (page 93) and adjust the
individual speaker levels (page 94).
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 113).
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
“Left/Right” (page 98).
Check the Speaker Configuration (page 90).
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 listen-
ing mode with a mono source, such as an AM radio
station or mono TV program, the sound is concen-
trated in the center speaker.
In the Mono listening mode, only the front speakers
output sound if the “Output Speaker” setting is set to
“Center” (page 98).
Make sure the speakers are configured correctly
(page 90).
The surround speakers produce no sound
When the Stereo or Mono listening mode is selected,
the surround speakers produce no sound.
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 90).

If you can’t resolve the issue yourself, try resetting
the AV receiver before contacting the dealer.

will appear on the display and the AV receiver will
enter Standby mode.

radio presets and custom settings.
