Troubleshooting
First check the followings.
Since the issue may be caused by other components that
are connected, be sure to also check them while referring
to their manuals.
Further product operating procedures and FAQs
(frequently asked questions) are available from the Onkyo
web site.

Can’t turn on the Integrated Amplifier.
• Make sure that the power cord is properly plugged into
the wall outlet (➔ page 14).
• Unplug the power cord from the wall outlet, wait 5
seconds or more, then plug it in again.
The Integrated Amplifier turns off unexpectedly.
• When the protection circuit is activated (because of speaker
short-circuit, overload, or over-current), the integrated
amplifier enters Standby mode. Remove the source of the
problem and turn the integrated amplifier back on.
• Check that the switch on the back of the integrated
amplifier is set to the correct setting (
➔ page 25 ).
• The settings are not enabled when the switch is changed
during the Standby mode.
To change a setting, be sure to turn on the unit prior to
making any changes.
There’s no sound.
• Make sure the integrated amplifier’s volume control is
not set to minimum (➔ page 22).
• Make sure the correct input source is selected
(➔ page 23).
• Make sure the integrated amplifier is not muted
(➔ page 24).
• Make sure the speakers are connected correctly ( ➔ page 12 ).
• Check all connections and correct as necessary ( ➔ page 12 ).
• While headphones are connected, the speakers output no
sound (➔ page 24).
• The integrated amplifier does not support digital formats
other than PCM. Inputting a digital format other than
PCM will cause loud noise.
The sound quality is not good.
• Make sure the speaker cables are connected with the
correct polarity (➔ page 12).
• Make sure all audio connecting plugs are pushed in all
the way (➔ page 14).
• The sound quality can be affected by strong magnetic
fields, such as those from a TV. Try moving any such
devices away from the integrated amplifier.
• If you have any devices that emit high-intensity radio
waves near the integrated amplifier, such as a cellular
phone that’s being used to make a call, the integrated
amplifier may output noise.
Headphone output is intermittent or there’s
no sound.
• This may be due to dirty contacts. Clean the headphones
plug. See your headphones’ instruction manual for
cleaning information. Also, make sure that the
headphones cable is not broken or damaged.
Audio performance
• Audio performance will be at its best about 10 to 30
minutes after the integrated amplifier has been turned on
and had time to warm up.
• Using cable ties to bundle audio cables with speaker or
power cables may degrade the sound quality, so refrain
from doing it.
• Depending on the country, the integrated amplifier may
be polarity-sensitive. In this case, plug the power cord in
a way that provides the best sound quality.
• Install the integrated amplifier on a sturdy rack or shelf.
Position it so that its weight is evenly dispersed on its
four legs. Do not install the integrated amplifier in a
place with vibration or an unstable location.
• Plug the power cord into an AC wall outlet.
Tip
Before requesting repairs
If the integrated amplifier is no longer working or
functioning, any issues may be resolved by resetting the
microcomputer contained in the integrated amplifier to
revert all settings to their defaults.
Before requesting repairs, follow the procedure below
to reset the microcomputer.
With the integrated amplifier turned on, hold down
DIRECT and press 8ON/STANDBY.
