A:Answer Hello there! We understand your inquiry about whether the LG S20A 2.0-Channel Soundbar will work with your LG 65UM6900PUA TV. Great news—it’s fully compatible and you have two easy ways to connect:
HDMI ARC (Recommended)
• Use an HDMI cable to connect the soundbar’s HDMI OUT (ARC) port to your TV’s HDMI 2 (ARC) port.
• On your TV, go to Settings > Sound > Sound Out, and select HDMI ARC.
• On the soundbar remote, ensure HDMI ARC is selected as the input.
This setup also lets you control volume with your TV remote via HDMI-CEC.
Wireless Bluetooth
• On the soundbar, press and hold the Bluetooth button until the LED flashes.
• On your TV: Settings > Sound > Sound Out > Bluetooth, then select LG S20A from the list.
• Once paired, audio will stream wirelessly from your TV to the soundbar.
Troubleshooting Tip: If you don’t hear sound after connecting via HDMI ARC, first verify that SimpLink (HDMI-CEC) is enabled on your TV (Settings > General > SIMPLINK (HDMI-CEC)). Then power-cycle both devices: turn them off, unplug from power for 30 seconds, plug back in, and restart. This refreshes the HDMI handshake and often resolves handshake issues.
