Introduction

LG sound bars come in various shapes and sizes and can accommodate nearly any budget. A sound bar is a great alternative to a full-blown home theater system, and can give your out-of-the-box TV audio more than a little added pop. Common issues you can run into with LG sound bars include no audio, power problems, remote control problems, and more. Use troubleshooting to work through these challenges and get your soundbar back up and running.

Sound Bar Won't Turn On

Check that the power cable connected to the LG sound bar is firmly connected. If the device still isn't working, verify that the outlet you're attempting to connect the sound bar to doesn't work by connecting a device that you know does, such as a lamp. If that device works, then you'll need to contact LG and raise the issue with them, or return the device to the reseller you purchased it from and see if you can exchange it.

No Sound from Sound Bar

  • If you are playing audio from a connected Bluetooth device, ensure that the volume is turned up on both the source device and the LG sound bar. Also, ensure that neither the sound bar or the source device is muted.
  • Verify that you've selected the correct input source. Check the back of the device to ensure you know what input to look for. Also, try cycling through the inputs in the event you misread the input the device was actually connected to and that audio is actually coming out of another input.

No Sound from Subwoofer

  • Make sure the subwoofer associated with the sound bar is firmly connected to the outlet it's plugged into.
  • If the unit is getting power, the issue is most likely associated with the Bluetooth connection. Un-pair and then re-pair the subwoofer with the sound bar to see if this resolves your issue.

Remote Control Won't Work

  • Ensure that the remote control is within roughly 30 feet of the LG sound bar. Also, ensure that the two devices have a clear line of sight to each other.
  • Try putting fresh batteries in the remote control to see if that resolves the issue. If the batteries in the remote are low, the device will connect intermittently and won't work at longer distances.

Can't Connect LG Sound Sync

The LG Sound Sync feature lets you control the audio volume associated with your sound bar through an LG TV that supports the Sound Sync feature. Setting the functionality up requires an initial pairing. If you've already paired the two LG devices but are not able to control the sound bar's volume using your TV remote, try un-pairing and then re-pairing the two devices in the Sound Sync section on your TV. Alternatively, if you didn't pair the device's previously, verify that you're TV actually supports the Sound Sync feature.

Low Audio Volume

If the audio being outputted through your sound bar feels low, try the following options:

  • Navigate to the audio settings on your TV and try changing the Audio Digital Output option to either Auto, Bitstream, or Primary Pass Through.
  • Check your TV's audio settings and verify that dynamic range compression (DRC) is turned off.

Poor Sound Quality

  • Nearby devices that send and receive wireless signals are the biggest offenders when it comes to interfering with the audio output quality of Bluetooth speakers. Consider moving these types of devices, such as baby monitors or other large electronic devices, to a different location.
  • The issue may not actually be with your LG sound bar, but rather with the audio quality of what you're watching. For example, if you're watching TV through either a dish service or an HD antenna, rain or a cloudy day could interfere with the audio feed associated with the show you're watching.

Factory Reset

Try resolving any other issues you experience by resetting the device to its factory default settings by doing the following:

  1. Hold down the "+" button until you hear a beep come from the device and you see "Disabled" appear on the device's screen. Hold down the "+" button again until you hear it beep twice and "Reset" appears on the device's screen. The device has been successfully reset to its default factory settings.
