If you have any trouble using the AV receiver, look for a 
solution in this section. 

 

• 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 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.

 

• 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 

 

• When the Stereo or Mono listening mode is selected, 

only the front speakers and subwoofer produce sound.

• Make sure the speakers are configured correctly 

 

• 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 

 

• 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 

 

• When the Stereo or Mono listening mode is selected, 

the center speaker produces no sound (page 45).

• Make sure the speakers are configured correctly 

 

• 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 

• 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.

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