If you have any trouble using the 7.1ch Home Theater 
System, look for a solution in this section. 

 

• 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 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 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.

 

• Make sure that the digital input source is selected 

properly (page 35). Press the [DIGITAL INPUT] but-
ton repeatedly.

• Make sure the speker set A or B is on (page 5).
• 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 wire is in contact with metal 
part of each speaker terminal (page 19)

• Make sure that the speaker cables are not shorting.
• Check the volume. It can be set to MIN, 1 through 79, 

or MAX (page 36). The AV receiver is designed for 
home theater enjoyment and has a wide volume range 
for precise adjustment.

• If the MUTING indicator is shown on the display, 

press the remote controller’s [MUTING] button to 
unmute the AV receiver (page 44).

• While a pair of headphones is connected to the 

PHONES jack, no sound is output by the speakers 
(page 45).

• Check the digital audio output settings 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 IIx Movie, Pro Logic IIx 

Music, or 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 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 48).

• 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 48).

• Make sure the speakers are configured correctly 

 

• While speaker set B is on, speaker set A is reduced to 

5.1-channel playback and the surround back speakers 
produce 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.
