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 your Onkyo 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 immedi-
ately and contact your Onkyo dealer.
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 the
metal part of each speaker terminal (page 22).
• Make sure that the input source is properly selected
(page 51).
• Make sure that the speaker cables are not shorting.
• Check the volume. It can be set to MIN, 1 through 99,
or MAX (page 51). 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 52).
• While a pair of headphones is connected to the
PHONES jack, no sound is output by the speakers
(page 52).
• 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 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 connect 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 62).
• Specify the speaker distances (page 47) and adjust the
individual speaker levels (page 48).
• 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 44).
Only the center speaker produces sound?
• If you use the Pro Logic IIx Movie or Pro Logic IIx
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 44).
The surround speakers produce no sound?
• When the Stereo or Direct listening mode is selected,
the surround speakers produce no sound (page 62).
• 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 44).
The center speaker produces no sound?
• When the Mono or Stereo listening mode is selected,
the center speaker produces no sound (page 62).
• Make sure the speakers are configured correctly
(page 44).
The surround back speakers produce no
sound?
• The surround back speakers are not used with all lis-
tening modes. Select another listening mode
(page 62).
• Not much sound may be produced by the surround
back speakers with some sources.
• Make sure the speakers are configured correctly
(page 44).
