Have TV Questions? Ask a TV Technician
Hello, my name is Rusty. You won't need the HDMI cable for this, only the optical cable. Be sure both ends are seated completely. Sometimes they can feel like they are seated, when they are not.
In your TV, press the tools button, then choose speaker list. Turn the TV speakers off, to make sure the external sound system is activated. Press OPTICAL on your soundbar remote to select the optical input.
Depending on what you listen to, the different sound modes will be optimized for different things. Press the SOUND EFFECT button on your LG remote repeatedly to go through the different sound modes until you find one you like best. If you like it best, ***** ***** is the correct setting. The list will repeat, so if you want to go back to a certain mode, keep pressing the button and it will come back around on the list.
