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.
