Thank you for your interest in the LG LG 75 Inch Class QNED80 URA Series 4K UHD Smart webOS 23 w/ThinQ AI TV 75QNED80URA (75QNED80URA) model. Here are the easy steps to connect an old surround sound system to your LG 75QNED80URA TV: 1. Check the available audio outputs on your TV, which can be HDMI ARC, optical, or Bluetooth. 2. Use an HDMI cable to connect the TV's HDMI ARC port to the HDMI ARC port on the sound system if it supports HDMI ARC. For systems without HDMI ARC support, use optical or RCA cables to connect to the TV's corresponding output. 3. Configure audio settings on the TV by going to All Settings > Sound > Sound Out and choosing the appropriate audio output option. 4. Configure audio settings on the sound system by selecting the correct input source based on the TV connection - HDMI ARC, optical, or analog. 5. Test the audio playback by playing a movie or TV show and checking if the sound comes from the surround sound system. Adjust volume as needed.
