Troubleshooting
If you have any trouble using the AV receiver, look for a
solution in this section.
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. Disconnect all speaker cables and input sources,
and leave the AV receiver with its power cord discon-
nected for one hour. After that, reconnect the power
cord, and then set the volume to maximum. If the AV
receiver stays on, set the volume to minimum, discon-
nect the power cord, and reconnect your speakers and
input sources properly. If the AV receiver turns off
when you set the volume to maximum, disconnect the
power cord, and contact your Onkyo dealer.
There’s no sound or it’s very quiet?
• Press the SPEAKERS [A] or [B] button to turn on the
indicator for the speakers that you want to output
sound.
• Make sure that the digital input source is selected
properly (page 33). Press the [DIGITAL INPUT] but-
ton repeatedly.
• Make sure that all audio connecting plugs are pushed
in all the way (page 22).
• 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 (pages 18, 19)
• Make sure that the speaker cables are not shorting.
• Check the volume. The AV receiver is designed for
home theater enjoyment and has a wide volume range
for precise adjustment (page 36).
• If the MUTING indicator is shown on the display,
press the remote controller’s [MUTING] button to
unmute the AV receiver (page 43).
• While a pair of headphones is connected to the
PHONES jack, no sound is output by the speakers
(page 42).
• Check the digital audio output setting on the con-
nected device. On some games consoles, such as those
that can play DVDs, the default setting is off.
•With some DVD-Video discs, you need to select an
audio format from a menu.
• If your turntable doesn’t have a phono preamp built-in,
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 a
phono preamp.
• Specify the speaker distances and adjust the individual
speaker levels (pages 52, 53).
• The input signal format is set to PCM or DTS. Set it to
Auto (page 53).
Only the front speakers produce sound?
• When the Stereo or Mono listening mode is selected,
only the front speakers and subwoofer produce sound.
• Make sure the speakers are configured correctly
(page 34).
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 34).
The surround speakers produce no sound?
• When the Stereo or Mono listening mode is selected,
the surround speakers produce no sound (page 45).
• 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 34).
The center speaker produces no sound?
• When the Stereo or Mono listening mode is selected,
the center speaker produces no sound (page 45).
• Make sure the speakers are configured correctly
(page 34).
The subwoofer produces no sound?
• The subwoofer outputs no sound while only speaker
set B is on. Turn on speaker set A.
• When you play source material that contains no infor-
mation in the LFE channel, the subwoofer produces
no sound.
• Make sure the speakers are configured correctly
(page 34).
• If the multichannel DVD input is selected and speaker
set B is on, speaker set A is reduced to 2-channel play-
back, so the subwoofer outputs no sound.

If you can’t resolve the issue yourself, try resetting
the AV receiver before contacting your Onkyo dealer.
To reset the AV receiver to its factory defaults,
turn it on and, while holding down the [VIDEO 1]
button, press the [STANDBY/ON] button. “Clear”
will appear on the display and the AV receiver will
enter Standby mode.
Note that resetting the AV receiver will delete your
radio presets and custom settings.
