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.

 

• 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 and contact your Onkyo dealer.

 

• 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 21).

• 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 53).

• Make sure that the speaker cables are not shorting.
• Check the volume. It can be set to MIN, 1 through 99, 

or MAX (page 53). The AV receiver 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 (page 54).

• While a pair of headphones is connected to the 

PHONES jack, no sound is output by the speakers 
(page 54).

• 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. 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 62).

• Specify the speaker distances (page 49) and adjust the 

individual speaker levels (page 50).

still connected.

front speakers and subwoofer produce sound.

ing mode is selected, only the front speakers produce 
sound.

(page 46).

 

• If you use the Pro Logic IIx Movie or Pro Logic IIx 

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 

(page 46).

 

• When the Stereo, Direct, or Pure Audio (not all mod-

els) listening mode is selected, the surround speakers 
produce no sound (page 62).

• 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 

(page 46).

 

• When the Mono or Stereo listening mode is selected, 

the center speaker produces no sound (page 62).

• Make sure the speakers are configured correctly 

(page 46).

tening modes. Select another listening mode 
(page 62).

back speakers with some sources.
