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
