Frequently Asked Questions

LG soundbar power light is on but no sound at all?

If the power light is on but no audio, check the selected input and confirm the TV audio output is set to the soundbar — not TV Speaker.

LG soundbar rear speakers not producing sound?

LG wireless rear speakers require their own power and a paired wireless module. Check the rear speaker unit is powered on and the LED is solid — not flashing.
