Before starting the procedure
When operation is unstable, problems may be solved
by simply turning the power on or to standby or
disconnecting/connecting the power cord, rather than
reviewing settings and operations. Try the simple
measures on both the unit and the connected device. If
the problem isn't fixed after referring to
"Troubleshooting", resetting the unit to the status at the
time of shipment may solve the problem. Note that your
settings will also be initialized when you reset, so we
recommend that you note down your settings before
doing the following.

settings to the default)
1. Press on the remote controller, select "Factory
Reset" in the menu and press ENTER.
2. Press ENTER.

reset.
