LG Subwoofer Not Working

LG Electronics is a multi-billion dollar electronics company located in South Korea which is well known for its high quality products. LG is also well known for their close attention to quality control. This is why it is so maddening if your LG Subwoofer is not working.  Since a subwoofer, which is also called a sub, reproduces low frequency sounds that are lower in frequency than woofers produce, this means that you will be missing out on many bass and sub-bass sounds produced by your LG Subwoofer.  Some simple troubleshooting steps can lead you to determining the etiology of this problem so you can quickly resolve it.

If your LG Subwoofer is not working, first try turning your LG Soundbar’s volume down by pressing down on the Volume – button and then checking the LG Subwoofer again. If this does solve the problem, unplug the LG Soundbar and re-plug it after 5 minutes.

If this still does not solve the problem, you can try to manually connect your LG Subwoofer with your LG Soundbar. Continue pressing on Volume Down and in a short amount of time, the LG Soundbar should  light up with a Red Color. Then, after about two seconds, the solid red light should start to flash.

Now, take your Remote and then press down on the Mute button for about three seconds. Keep pressing down on the Mute Button until you start to see the LCD indicator light start to flash quickly.

If your LG Subwoofer is blinking green, it means that the connection between the LG Subwoofer and your LG Soundbar has either been disconnected or is not functional. You will also notice that the LG subwoofer is not producing any sounds. If this is the case, some easy troubleshooting steps can determine the cause of the problem so that you can quickly resolve it.

If your LG subwoofer is not working, and it keeps blinking green, adjust the volume level to lower levels until you see the message Vol Min appear. Then press and hold down the Mute button on the LG Remote Control for a period of about three seconds. You should then see the message of WL Reset.

Press and then hold down Pairing on the back of the LG Subwoofer.

Also, make sure that the LG Subwoofer and the LG Soundbar are installed within about fifteen or sixteen feet of each other. Make sure that there is nothing obstructing the path between the LG Subwoofer and the LG Soundbar.

In addition, check for any other devices that might be interfering that are on the same Wi-Fi network, such as microwaves or wireless LAN devices or various kinds of medical equipment such as heart monitors.

If your LG Subwoofer is not working and keeps cutting out,  it can be extremely frustrating and annoying.  You may be able to resolve this problem by resetting the signal from the LG Soundbar to the LG subwoofer.

If this does not solve the problem, try pressing the Stop button on the LG Soundbar along with the 6 Button on the Remote at the same time for a period of about five seconds. Now you should see the message indicating WL Reset. Then press Pairing on the back of the LG Subwoofer with a pen or paperclip.

You should then see the green and red lights blinking alternately. Unplug the power supply to both the LG Subwoofer and the LG Soundbar. Then plug in both units and turn them on. At this point, if you see the green LED light of the Woofer first blinking quickly and then turning a solid green, check to see if the LG Subwoofer is producing sound normally.

If your LG subwoofer is not pairing with your soundbar, it could be due to wear and tear, connection problems, overheating, or short circuits. To fix the issue, you can try checking the power connection, fixing the Bluetooth pairing, lowering the volume, checking the LED indicator, or connecting manually. If these steps do not work, contact LG support for further assistance.

There are several possible reasons why your LG subwoofer may not be pairing with your soundbar, including wear and tear, connection issues, overheating, and short circuits. To address the problem, you can try the following solutions:

  1. Verify the power connection: Ensure that the power cord is securely connected to both the outlet and the subwoofer.
  2. Repair the Bluetooth pairing: Unpair the devices and then pair them again to see if this resolves the issue.
  3. Reduce the volume: If the volume on your LG soundbar is too high, it may not connect to the subwoofer. Try lowering the volume and attempting to connect again.
  4. Monitor the LED indicator: The LED on the wireless subwoofer can provide information about its connection status. A blinking green LED indicates that a connection is being established, a solid green LED indicates a successful connection, a red LED indicates a bad connection or that the subwoofer is in standby mode, and an unlit LED indicates that the power cable is not connected.
  5. Manually connect: Turn off the soundbar by pressing the [Power] button, then press the [Pairing] button on the back of the wireless subwoofer. Check if the LED on the back of the subwoofer is blinking green. If you still see a red LED on the wireless subwoofer, press and hold the button on the back of the subwoofer again for 5 seconds. Turn on the soundbar by pressing the [Power] button. When a connection is established, you will see a green LED light up on the back of the wireless subwoofer.

If these steps do not resolve your issue, you may want to contact LG support for further assistance.
