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 5
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 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 your Onkyo dealer.
There’s no sound or it’s very quiet
• Make sure that the digital input source is selected
properly (page 59).
• Make sure that the correct audio input is selected
(page 120).
• Make sure that all audio connecting plugs are pushed
in all the way (page 33).
• 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 23).
• 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 70). The AV receiver is
designed for home theater enjoyment. It has a wide
volume range, allowing precise adjustment.
• If the MUTING indicator is flashing on the display,
press the remote controller’s [MUTING] button to
unmute the AV receiver (page 71).
• While a pair of headphones is connected to the
PHONES jack, no sound is output by the speakers
(page 72).
• 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 use
an MC head amp or MC transformer (page 46).
• Check the speaker settings (pages 95–102).
• The input signal format is set to PCM or DTS. Set it to
“Auto” (page 120).
• 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.
• Make sure that none of the connecting cables are bent,
twisted, or damaged.
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 106).
• Check the Speaker Configuration (page 95).
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
“C” (page 106).
• Check the Speaker Configuration (page 95).
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 the current listening
mode, not much sound may be produced by the sur-
round speakers. Try another listening mode (page 81).
• Make sure the speakers are configured correctly
(page 95).
The center speaker produces no sound
• When the Stereo listening mode is selected, the center
speaker produces no sound.
• In the Mono listening mode, only the front speakers
output sound if the “Output Speaker” setting is set to
