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 plugged into the wall
outlet properly.
• Unplug the power cord from the wall outlet, wait 5
seconds or more, then plug it back 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. Disconnect 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 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.
• HDMI audio is passed through the AV receiver and
can only be heard from your TV.
• To listen to an audio source that’s connected to an
OPTICAL or COAXIAL input, make sure that input is
assigned to an input selector (page 36).
• Make sure that all audio connecting plugs are pushed
in all the way (page 18).
• Make sure that the polarity of the speaker cables is
correct, and that the bare wire is in contact with the
metal part of each speaker terminal (page 14).
• Make sure that the speaker cables are not shorting.
• Check the volume (page 38). The AV receiver is
designed for home theater enjoyment and has a wide
volume range for precise adjustment.
• If the MUTING indicator is flashing on the display,
press the remote controller’s [MUTING] button to
unmute the AV receiver (page 39).
• While a pair of headphones is connected to the
PHONES jack, no sound is output by the main room
speakers (page 40).
• Check the digital audio output settings on the source
component. On some game 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 or with the [AUDIO] button
on your DVD player’s remote controller.
• 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
connect an MC head amp, or an MC transformer and
a phono preamp.
• Check the speaker settings (pages 54–56).
• If the digital signal format is set to PCM or DTS, set it
to “Auto” (page 41).
Only the front speakers produce sound
• When the Stereo or Mono listening mode is selected,
only the front speakers and subwoofer produce sound.
• Check the “3. Sp Config” (page 54).
Only the center speaker produces sound
• If you use the Dolby Pro Logic II Movie or Dolby Pro
Logic II Music listening mode with a mono source,
such as an AM radio station or mono TV program, the
sound will be concentrated in the center speaker.
• Check the “3. Sp Config” (page 54).
The center speaker produces no sound
• When the Stereo or Mono listening mode is selected,
the center speaker produces no sound (page 53).
• Check the “3. Sp Config” (page 54).
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
surround speakers. Try another listening mode
(page 49).
• Check the “3. Sp Config” (page 54).

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

turn it on and, while holding down the [VCR/DVR]
