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 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 turns off as soon as it’s turned 
on
• 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.

designed for home theater enjoyment. It has a wide 
volume range, allowing precise adjustment.

• While a pair of headphones is connected to the 

PHONES jack, no sound is output by the speakers 
(page 58).

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.

nect an MC head amp, or an MC transformer.

• If you use the Dolby Pro Logic IIx Movie, Dolby Pro 

Logic IIx Music, or Dolby Pro Logic IIx Game listen-
ing mode with a mono source, such as an AM radio 
station or mono TV program, the sound is concen-
trated in the center speaker.

• In the Mono listening mode, only the front speakers 

output sound if the “Output Speaker” setting is set to 
“Center” (page 84).

• Make sure the speakers are configured correctly 

(page 80). 

The onscreen setup menus appear only on a TV that is 
connected to the HDMI OUT. If your TV is connected 
to the composite video or S-Video MONITOR OUT, 
or the COMPONENT VIDEO MONITOR OUT, use 
the AV receiver’s display when changing settings.

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.
