LG Subwoofer Not Connecting to Soundbar – Solved

The LG Subwoofer and soundbar combo are great for beginning home theatre enthusiasts. These combinations are made with beginners in mind, and they deliver great sound for the price. However, some have had issues with the subwoofer and soundbar connecting. Some wireless connections are trickier than others, but it doesn’t mean your devices aren’t working. 

This problem has come up a lot in my years as a home theatre enthusiast. Now, it’s time to solve the issue once and for all – with as little hassle as possible.

Keep reading to find out what to do if your LG subwoofer does not connect to soundbar, and how you can minimize the risk of the connection failing. 

Connecting the LG Subwoofer to Soundbar 

Though it’s meant to be relatively easy, connecting your LG Subwoofer to your soundbar can be a bit tricky. This is especially true because of the way the subwoofer connects – if certain conditions aren’t met, the subwoofer may refuse to pair with the soundbar. 

So what if your LG subwoofer is not connecting to your soundbar? First, make sure that your subwoofer and soundbar are connected properly the first time. 

As soon as you turn on your LG subwoofer and soundbar, they should pair automatically. To trigger this first-time connection:

  1. Find the power cord for the soundbar. Plug one end of the power cord into the appropriate location on the back of the soundbar (labeled DC IN).
  2. Find the power cord for the subwoofer. Plug one end of the power cord into the appropriate location on the back of the subwoofer (labeled DC IN). 
  3. Power on the soundbar and the subwoofer by using the power button on each device. 
  4. When both devices are powered on, there will be a blinking LED light on the subwoofer. It usually takes a few moments for the subwoofer and the soundbar to communicate. They are programmed to connect only to each other, however.
  5. When the LED light goes solid green and stops blinking, the connection is completed. 

If this is the first time you’re turning both devices on and they don’t pair, you may have to pair them manually. 

You’ll know that the LG subwoofer and soundbar aren’t paired correctly if there is no sound, or if the LED light continues to blink several moments after turning both devices on. 

Troubleshooting Your Connection

There could be a few reasons that your LG subwoofer and soundbar aren’t connecting. Before attempting to manually connect your soundbar and subwoofer, investigate the following solutions:

  • Make sure that your LG subwoofer and soundbar are as close as possible. This improves the sound quality, but it also makes it easier for the devices to connect. 
  • Check to see if there are any obstructions between your LG soundbar 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. This can be medical devices, microwaves, and even some wireless LAN connections. If there are too many connections, it can cause interference that won’t allow your soundbar to connect to your subwoofer. 
  • Try turning the volume down. 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 problems seem to be the issue, try unplugging both the LG soundbar and subwoofer. Leave them unplugged for at least five minutes, and then plug both back in. This seems to fix the problem sometimes. 

Manually Connecting the LG Subwoofer to Soundbar

If your LG subwoofer and soundbar don’t connect right away, you might have to manually pair them. This is a simple process, but the steps must be followed exactly. 

To manually pair your LG subwoofer to the LG soundbar, follow these steps: 

  1. Turn the volume on the soundbar down. You can do this by pressing the ‘VOL –‘ button on the unit or the remote. This is essential to a proper pair, but this button also initiates manual pairing mode. 
  2. Now, continue to press the ‘VOL –‘ button. Soon, the LED located on the back of your soundbar should illuminate. It should be red. After 2 seconds, the solid light should begin to flash. 
  3. When the red LED indicator is flashing, find your remote. 
  4. Press and hold the ‘Mute’ button on your remote for three seconds. The mute button may be represented by an image of a speaker with a line through it. 
  5. Hold the ‘Mute’ button until the LED indicator light begins flashing quickly. There should be a noticeable difference between this speed and the slower blinking from before. 
  6. Next, move to your LG subwoofer. Find the pairing button on the back of the subwoofer. You’ll need a small tool, such as a miniature screwdriver or paperclip, to access the button. It’s very small and inset into the surface of the subwoofer. 
  7. Use the small tool to press the pairing button for more than 5 seconds. 
  8. The LED indicator light should begin flashing red and green in an alternating pattern. 
  9. At this point, you should unplug both the subwoofer and the soundbar. Keep them completely unplugged from any power source for a few moments. 
  10. Now, plug the subwoofer and the soundbar back into a power source. After a few moments, the devices should automatically pair. You can tell that they are paired by looking at the LED indicator light on the other side of the subwoofer. It should be solid green.

After taking these steps, your LG subwoofer and soundbar should be paired. You can test this by attempting to play something from your TV. If you can hear sound from both the soundbar and the subwoofer, the pair was successful. 

Conclusion

Most of the time, the LG subwoofer and soundbar combination pair easily and without a fuss. If your LG subwoofer does not connect to soundbar, it might be an easy enough fix. If these steps don’t fix your connection, you might have to get your LG subwoofer and soundbar repaired.
