connection troubleshooting

There may be a few reasons why your lg subwoofer and soundbar won’t connect. Before attempting to manually connect your soundbar and subwoofer, please investigate the following solutions:

  • make sure your lg subwoofer and sound bar are as close as possible. this improves sound quality, but also makes it easier to connect devices.
  • check for obstructions between your lg sound bar and the subwoofer. anything that might be blocking the signal can affect connectivity.
  • turn off devices that use the same frequency as the lg subwoofer or soundbar. These can be medical devices, microwaves, and even some wireless LAN connections. if there are too many connections, it can cause interference that will not allow your sound bar to connect to your subwoofer.
  • try to lower the volume. For some reason, it’s easier for your subwoofer to connect to your soundbar if the soundbar’s volume is turned down.
  • if none of these seem to be the problem, try unplugging the lg soundbar and subwoofer. leave them unplugged for at least five minutes and then plug them back in. this seems to fix the problem sometimes.
