Troubleshooting
If you have any trouble using the AV receiver/AV ampli-
fier, 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/AV amplifier
• 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/AV amplifier 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/AV amplifier 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/AV
amplifier stays on, set the volume to minimum, discon-
nect the power cord, and reconnect your speakers and
input sources. If the AV receiver/AV amplifier 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 51). Press the [DIGITAL INPUT] but-
ton repeatedly.
• 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 29-42).
• 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 input source is properly selected
(page 59).
• Make sure that the speaker cables are not shorting.
• Check the volume. It can be set to
−∞ dB, −81 dB
through +17, +18 dB (page 59). The AV receiver/AV
amplifier 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/AV amplifier (page 61).
• While a pair of headphones is connected to the
PHONES jack, no sound is output by the speakers
(page 61).
• 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 doesn’t have a built-in phono
preamp, you must connect one between it and the AV
receiver/AV amplifier. 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 71).
• Specify the speaker distances (page 80) and adjust the
individual speaker levels (page 81).
• 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 97).
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 85).
• Check the Speaker Configuration (page 77).
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 77).
