The TV automatically turns off its internal speakers and sends volume and mute control signals to an
external amplifier when all of the following are true:
System audio control is enabled on the TV.
A CEC-compatible amplifier is powered on and CEC discoverability is enabled.
The CEC-compatible amplifier’s HDMI ARC connector is connected to the TV’s HDMI ARC
connector with a suitable HDMI cable.
When the CEC-compatible amplifier is off, the TV automatically turns on its speakers (unless you have
turned them off as described in “Turning off TV speakers” on page 51
) and resumes local control of
volume and mute state.
System audio control is disabled by default. To enable system audio control, in the Home screen menu,
navigate to Settings > Control other devices (CEC) and highlight System audio control. Press OK to
check the adjacent check box.
Enabling 1-touch play
1-touch play enables a component to control which TV input is active. For example, pressing Play on
your Blu-ray player switches the TV to the Blu-ray input.
1-touch play is disabled by default. To enable 1-touch play, in the Home screen menu, navigate to
Settings > Control other devices (CEC) and highlight 1-touch play. Press OK to check the adjacent check
box.
Enabling system standby
The system standby feature causes other components to power off when you power off your TV.
Depending on the CEC System Standby implementation, it also might enable connected components to
power off your TV when you power off the component.
System standby is disabled by default. To enable system standby, in the Home screen menu, navigate to
Settings > Control other devices (CEC) and highlight System standby. Press OK to check the adjacent
check box.
Restarting the TV
You can restart the TV when necessary. Restarting has the same effect as unplugging the TV power and
then plugging it in again.
To restart the TV, navigate to Settings > System > Power and then move right to System restart and
then Restart. Press OK to confirm restart.
While the TV restarts, the screen goes dark for a few seconds, and then displays the startup screen for a
few more seconds. When the restart operation is complete, you’ll see the familiar Home screen.
