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).

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

Note that resetting the AV receiver/AV amplifier will 
delete your radio presets and custom settings.
