Discovering connected CEC devices
To discover CEC devices:
1. Make sure that your CEC-compatible components are connected to the TV with a suitable high-speed HDMI cable that
supports HDMI ARC and CEC control.
2. Turn on each component and make sure all components have CEC enabled.

3. On the TV's Home screen menu, navigate to Settings > System > Control other devices (CEC) > Search for CEC
devices, and then press [OK] to start the discovery process.

Enabling HDMI ARC
HDMI ARC is the audio return channel that is available on one of the TV's HDMI ports. The audio return channel enables you
to send a Dolby Digital audio signal back to a home theater receiver that is also sending an audio and video signal into the
TV. Using HDMI ARC reduces the number of cables needed and optionally lets you control the volume and mute state of the
receiver by enabling system audio control.
HDMI ARC is disabled by default. To enable HDMI ARC, in the Home screen menu, navigate to Settings > System > Control
other devices (CEC), and then highlight HDMI ARC. Press [OK] to check the adjacent check box.
Enabling system audio control
System audio control enables the TV remote control to change the volume and mute state of an amplifier or sound bar
connected through HDMI, and to display the external device's volume and mute status in the TV's on-screen display.
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.

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 > System >
