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. Turn off the device connected to this unit, then
disconnect and reconnect the cable. When reconnecting,
be careful not to wind the HDMI cable since if wound the
HDMI cable may not fit well.

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.

If operation becomes unstable
Try restarting the unit
The issue may be fixed by restarting this unit. After
switching this unit to standby, press and hold
Í
ON/
STANDBY on this unit for 5 or more seconds to restart the
unit.
(The settings in the unit are maintained.) If the issue is not
fixed by restarting, try unplugging the power cords of the
unit and connected devices, and then plugging them in
again.
Resetting the unit (this resets the unit settings to the
default)
If restarting the unit doesn't fix the problem, resetting the
unit to the status at the time of shipment may solve the
problem. Your settings will also be initialized when you
reset, so note down your settings before doing the
following.

press
Í
ON/STANDBY.
2. The unit switches to standby and the settings are reset.

The protective circuit function may have been activated.
If this has occurred, "AMP Diag Mode" appears on the
display when the unit is turned on again, and the unit
enters diagnostic mode. If the results of the diagnosis is
that there is no problem, the "AMP Diag Mode" display
disappears and you can use the unit normally again. If
"CHECK SP WIRE" appears on the display, the speaker
cables may be short-circuited. Make sure bare speaker
wires are not touching each other or the back panel of
the unit, then turn the unit on again. If "NG" is displayed,
immediately unplug the power cord from the wall outlet
and contact your dealer.

The protective circuit function may have been activated
because the temperature of the unit rose abnormally. If
this happens, then the power will continue to turn off after
you have turned the unit on again. Make sure the unit
has plenty of space for ventilation around it, wait for the
unit to cool down sufficiently, and then try turning it on
again.
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 customer support.
