If the HDMI cable is connected to the wrong terminal (HDMI AV IN or HDMI AV OUT), this system will not operate correctly. Turn the main unit off, disconnect the AC power supply cord and reconnect the HDMI cable(s).
Verify if the TV’s HDMI terminal is labeled “HDMI (ARC)”. ARC is an abbreviation of Audio Return Channel, also known as HDMI ARC. It refers to one of the HDMI functions. When the main unit is connected to the terminal labeled “HDMI (ARC)” on the TV, the optical digital audio cable that is usually required in order to listen to sound from a TV is no longer required. Video, pictures and sound can be enjoyed with a single HDMI cable.
Be sure to connect to the TV's ARC compatible terminal. (Refer to the operating instructions for the TV.)
