Philips sound bar systems can only be connected to an LG television using an optical digital audio connections. While many LG TVs also support HDMI ARC and digital coaxial connections, Philips soundbar systems aren't compatible with them. Likewise, Philips soundbars can connect to a TV via composite audio, but LG TVs don't support outputting sound via composite. By using an intermediary device, such as a cable set-top box, however, you can use HDMI, digital coaxial and composite audio, as well.
Optical Audio
Video of the Day
Optical digital audio connections use fiber optic cable to transmit audio signals digitally. Optical audio is the only output connection supported by both Philips soundbars and LG TVs, making it the only option if you can't or don't want to use another device as an intermediary between them.

Intermediary Devices
If you don't have an optical audio cable on hand, some other devices in your entertainment center can bridge the gap between your soundbar and TV. The strongest candidates are AV receivers or cable or satellite set-top boxes, as they typically feature enough inputs to accommodate several devices. To illustrate the following instructions, a cable set-top box is used as an example.
Step 1
Connect your soundbar to the cable box.
- Digital coaxial: Connect one end of the digital coaxial cable from the Digital In/Coaxial In port on your soundbar to the Digital Out or Coaxial Out port on the cable box.
- Composite: Connect one set of red and white connectors to the color coded L and R Audio-In ports on your soundbar and the other set of connectors to the L and R Audio-Out ports on your cable box.
Step 2
Connect the cable box to one of your TV's inputs.
- HDMI: Connect one end of the HDMI cable to the HDMI-Out port on the cable box and one of the HDMI-In ports on your TV.
- Composite: Connect one set of red and white connectors to the color coded L and R Audio-Out ports on your soundbar and the other set of connectors to the L/Mono and Audio R Component In/AV In ports on your device.
