Fixes For When Your LG SN6Y Subwoofer Is Not Turning On or Working

LG SN6Y Subwoofer Is Not Turning On or Working

So you just got your new home theater system and are excited for an evening of thumping sound effects and crisp, clear dialogues. The last thing you want to find out is that one of its components isn’t working. If your LG SN6Y subwoofer is not turning on or not working properly, you can take several troubleshooting steps.

Luckily, the majority of issues with subwoofers arise from user error. That said, there may be some potential issues with the component itself. Fortunately, we have some quick fixes so you can get back up and running as soon as possible! Continue reading to know why your LG SN6Y subwoofer is not working and how to fix it. Here are some tips:

1. Check the Connections

If you’ve just set up your new LG subwoofer and are experiencing issues, it’s always worth checking the connections. There are three main connection types: 

  • AC power – If your subwoofer is not receiving power, it will not work. Make sure that the power cable is securely connected to the power outlet.
  • Audio cables – The audio cables transmit the signals from the audio source to your components. If the cables are not plugged in correctly, the subwoofer will not work. 
  • HDMI cables – If the HDMI cables are not plugged in correctly, the subwoofer will not get any signal to play the sound or display video.

2. Reset Device

If you’ve just plugged your subwoofer in and it does not appear to be working, try resetting the device. 

  • Unplug the subwoofer from the power outlet.
  • Make sure that the plug is entirely removed from the socket.
  • Wait around 10 seconds. 
  • Plug the subwoofer back into the power outlet. 
  • The subwoofer should now power on.

3. Hard Reset

If the subwoofer is not responding to the reset, it may be necessary to perform a hard reset. 

  • Unplug the subwoofer from the power outlet 
  • Make sure that the plug is fully removed from the socket. 
  • Disconnect all audio cables from the device. 
  • Wait around 10 seconds. 
  • Reconnect the audio cables to the subwoofer. 
  • Plug the subwoofer back into the power outlet. 
  • The subwoofer should now power on.

4. Replace the Woofer’s Motherboard

If you’ve just replaced the woofers and are still experiencing issues, it may be that the motherboard needs replacing. Subwoofer issues that can’t be resolved by troubleshooting are usually the result of a hardware fault. 

In this case, the solution is to replace the motherboard. It is recommended to contact an expert for assistance since this isn’t a task for the inexperienced.

5. Contact LG Support

If you’ve just plugged your subwoofer in and it does not appear to be working, it is recommended to contact LG support for assistance. They will likely be able to diagnose the issue remotely and provide you with a solution. 

In addition, the technicians at LG are experts on their products and can advise on a range of topics. So if you have questions about your LG subwoofer, they are your first point of call.

Lg Subwoofer Connected, But No Sound

Lg Subwoofer Connected, But No Sound

Your subwoofer is connected, but you do not hear any sound; what should you do?


The first thing to check is the volume setting. Depending on how you connect the subwoofer, you may also need to adjust the delay setting. For example, if you connect the subwoofer via a cable, such as an optical cable, you may have the input signal set to the wrong device. 

You may also need to adjust the audio settings on your TV or soundbar. For example, if you connect the device via an HDMI connection, the volume setting on your TV or soundbar may need to be turned up. It is also possible that the delay setting may need to be adjusted.

LG Subwoofer No Power Light

If your LG subwoofer isn’t turning on, the first thing you should check is the power light. If the power light is off, the subwoofer may be either unplugged or not receiving power.


To fix this, ensure that the subwoofer is plugged into an outlet. If it is, check to see if there’s a power switch on the back of the subwoofer. If there is, make sure it’s turned on. 

However, if everything appears to be in order and the subwoofer isn’t turning on, you may need to reset the subwoofer. To do this, disconnect the power cord from the subwoofer and plug it back in. 

Once you’ve done this, press and hold the power button for 5 seconds, this should reset the subwoofer and hopefully get it working again.

LG Subwoofer Blinking Green Fast

If the green light on your LG Subwoofer is flickering, this indicates that the LG Subwoofer and LG Soundbar are no longer connected or that the connection is broken. Additionally, you’ll notice that the LG subwoofer is silent. If so, a few simple troubleshooting techniques will help you identify the issue’s root cause and rapidly fix it.


Reduce the volume entirely until you see the ‘minimum volume’ message. Next, hold the mute button on the LG remote control for roughly three seconds. The WL Reset notice should then appear.

On the LG Subwoofer’s back, press and hold “Pairing.”

Additionally, make sure the LG Soundbar and LG Subwoofer are situated within a distance of 15 to 16 feet. Finally, ensure that nothing is in the way of the LG Soundbar’s connection to the LG Subwoofer.

LG Subwoofer Red Light

If the red blinking light on your LG Subwoofer is present, the connection to the LG Subwoofer is not complete. Fortunately, you can fix this problem by taking a few simple actions to restore a connection.


Press the Subwoofer’s Pair button. Next, check whether you can see the green-yellow light on the subwoofer’s front-facing LED display. Finally, press and hold the pairing button once more if the green light does not blink.

The green light should be on when the LG Soundbar is turned on.

If this did not resolve the issue, try to simultaneously push the Mute and Stop buttons on the LG Soundbar until you see the message “Remate” appear on the LCD. Next, try pressing the LG Subwoofer’s pairing button once again.

LG Subwoofer Not Pairing

LG Subwoofer Not Pairing

The most common reason your LG sn6y subwoofer isn’t pairing is that it’s not in discovery mode.


To put it into discovery mode, press and hold the power button for 5 seconds. You should see a blue light on the subwoofer that indicates it’s in discovery mode. If you don’t see the blue light, try pressing and holding the power button for 10 seconds

If that doesn’t work, check the manual for your specific subwoofer model. Once you’ve put the subwoofer into discovery mode, open the Bluetooth settings on your phone or other device and look for “LG SN6Y.” The subwoofer should show up as an available device. Select it to pair the two devices.


If you’ve tried all of the above tips and your LG SN6Y subwoofer is still not turning on or working, it may be time to contact LG support. They should be able to help you identify and fix the issue with your device. Have you had any luck fixing your subwoofer? Let us know in the comments section below.


How do I pair my subwoofer with LG Soundbar SN6Y?

Pairing your subwoofer with your soundbar is a simple process that only takes a few minutes. First, connect the power cord of the soundbar and the wireless subwoofer to the outlet. After that, turn on the soundbar. The soundbar and subwoofer will be automatically connected. Alternatively, you can pair them manually by pressing “PAIRING” on the subwoofer’s rear.
The green LED on the back of the subwoofer should start blinking quickly. If it doesn’t, press and hold the “PAIRING” button for a few seconds. Once the green LED is blinking, turn on the soundbar. The pairing is now completed, and the green LED should be turned on. Enjoy your improved sound experience!

How do I reset my LG SN6Y?

If you need to reset your LG soundbar, there are a few ways of doing it. First, power the soundbar off and remove the power cord from the outlet. 
Once you’ve done this, wait for 20 seconds. After the 20 seconds have passed, plug everything back in and turn the soundbar on. This should reset the soundbar.
If this doesn’t work, or if you want to reset your soundbar to its factory settings, the best way is to power the soundbar off and wait for 10 seconds. Once the 10 seconds have passed, the soundbar will reset and return to its original factory settings.

Why did my subwoofer stop working?

There are a few possible reasons why your subwoofer might have stopped working. Check to ensure the power cord is plugged in and the outlet is working. The subwoofer may be the problem if the outlet is okay and the cord is securely plugged in.
If you have a warranty, now would be an excellent time to use it. If not, you may be able to fix the problem yourself by opening up the subwoofer and checking for loose wires or other issues. 
However, if you’re not comfortable opening up your subwoofer, it’s best to take it to a professional for repairs. With some troubleshooting, you should be able to figure out what’s wrong and get your subwoofer up and running again in no time.
