Troubleshooting
Before starting the procedure
Problems may be solved by simply turning the power on/off
or disconnecting/connecting the power cord, which is easier
than working on the connection, setting and operating
procedure. Try the simple measures on both the unit and
the connected device. If the problem is that the video or
audio is not output or the HDMI linked operation does not
work, disconnecting/connecting the HDMI cable may solve
it. When reconnecting, be careful not to wind the HDMI
cable since if wound the HDMI cable may not fit well. After
reconnecting, turn off and on the unit and the connected
device.
● The AV receiver contains a microPC for signal
processing and control functions. In very rare situations,
severe interference, noise from an external source, or
static electricity may cause it to lockup. In the unlikely
event that this happens, unplug the power cord from the
wall outlet, wait at least 5 seconds, and then plug it back
in.
● Onkyo is not responsible for damages (such as CD
rental fees) due to unsuccessful recordings caused by
the unit’s malfunction. Before you record important data,
make sure that the material will be recorded correctly.
Resetting the unit
Resetting the unit to the status at the time of shipment
may solve the problem. If the measures mentioned in the
troubleshooting do not solve the problem, reset the unit
with the following procedure. If you reset the unit status,
your preferences will be reset to the defaults. Note them
down before starting reset.
¼ How to reset
1. While holding down CBL/SAT on the main unit (note
that step 2 must be performed with this button pressed

Power
¼ Cannot turn on the unit
● Make sure that the power cord is properly plugged into
the wall outlet.
● Unplug the power cord from the wall outlet, wait 5
seconds or more, then plug it in again.
¼ The unit turns off unexpectedly
● The AV receiver will automatically enter standby mode
when Auto Standby or Sleep Timer is set and launched.
● The protection circuit may have been activated. If this is
the case, when you turn the unit on again, "AMP Diag
Mode" will appear on the main unit’s display. The unit
will then enter a mode that detects abnormal conditions.
If no problems are detected, "AMP Diag Mode" will
disappear and the unit will return to a normal state. If
"CHECK SP WIRE" appears on the display, the speaker
cables may be short-circuited. Turn the unit off, and
check to see if the cable core of any of the speaker
cables is in contact with that of another speaker cable or
with the rear panel. After that, turn the unit on again. If
"NG" appears, unplug the power cord immediately and
contact your Onkyo dealer.
WARNING: If smoke, smell or abnormal noise is produced
by the unit, unplug the power cord from the wall outlet
immediately and contact the dealer or Onkyo Support.
Audio
● Make sure that the speaker setup microphone is not still
connected.
● Check that the output jack of the connected equipment
and the input jack of this unit are connected correctly.
● Make sure that none of the connecting cables are bent,
twisted, or damaged.
● If the MUTING indicator on the display flashes, press
MUTING on the remote controller to unmute the unit.
● While headphones are connected to the PHONES jack,
no sound is output from the speakers.
● If "Audio Select" - "PCM Fixed Mode" is set to "On", set
it to "Off".
If the above does not solve the problem, check the
following.
¼ There is no sound from the television
● The input selector of this unit needs to be in the position
that corresponds to the jack where the television is
connected.
● If your TV does not support ARC, you need, in addition
to the HDMI OUT MAIN jack connection, a digital optical
cable connection between the digital audio out optical
jack of the TV and the DIGITAL IN OPTICAL jack of the
unit or an analog audio cable connection between the
audio output jack of the TV and the AUDIO IN TV jack of
the unit.
¼ There is no sound from the connected player
● The input selector of this unit needs to be in the
position that corresponds to the jack where the player is
