How Do I Connect LG TV to Yamaha Receiver Using an Optical Cable? 

Another way to connect your LG TV and Yamaha receiver are with an optical cable. If you do not have an HDMI cable or it is not working, you can use an optical cable. Let’s see the process of connecting it:

Step- 1: At first, take a high-quality optical cable. A cheaper one will drastically reduce your audio quality. 

Step- 2: Now, you have to plug in one end of that optical cable to the optical input port of your Yamaha receiver. 

Step- 3: Then take the other end and plug it in your LG TV’s output optical port.

Finally, your LG TV and Yamaha receiver are connected with an optical cable. 

Like HDMI, the optical cable also has its pros and cons. I will discuss them here. 


  • Optical cable connection uses only one cable and one port to connect your TV and receiver and provides excellent audio quality.  
  • This cable is pretty safe and will keep you away from any electric harm as it transmits light, not electricity. 
  • As light is fast, this optical cable is pretty fast too. 


  • You cannot connect any media source with your receiver and TV because optical cable can’t transmit video signals. They only transmit audio signals. 
  • You will need another connection for your video from the media source to your LG TV. 
  • It will increase the number of cables for your TV and receiver.
