Why Your LG Subwoofer is Blinking Green Fast and How to Fix It

Typically, the LG subwoofer displays a blinking green light as it tries to pair with the soundbar.

If the subwoofer keeps trying to discover the soundbar, the light will begin to blink fast. As long as the light blinks fast and continually, the subwoofer has a problem.

You may wonder why the LG subwoofer is blinking green fast despite the soundbar being near it. Truthfully, there are many reasons why your LG subwoofer won’t stop blinking green. But there are things you could do to troubleshoot an LG subwoofer below.

Keep the Soundbar Closer

Let’s face it; not everyone knows what distance is considered close. As a result, some people unknowingly place their soundbars very far from the subwoofer.

Generally, the distance between the subwoofer and the soundbar should be 10 feet away.

As you know, these devices rely on Bluetooth, which has a shorter range than WIFI. Admittedly, this can be frustrating for some who prefer their soundbars not to be close to the subwoofer.

However, Bluetooth’s low range is justified since it has a low-energy signal that helps preserve device batteries.

Reset the Audio System

Another reason your LG subwoofer blinks green fast could be issues with the power cycle audio system.

Sometimes, issues with the audio system can cause the subwoofer to begin blinking green and red. In this case, resetting the subwoofer and soundbar will remove any glitches.

To reset the audio system, here are the steps:

  • First, turn off the devices and unplug them from the power source. 
  • After that, you should wait at least a minute before reconnecting the devices. 
  • If you have not previously connected the devices, the blinking green light will be there, but this shouldn’t last long.

Remove Any Obstacles

Is your LG subwoofer still blinking green after a reset? Another reason may be the obstacles near it. These obstacles cut Bluetooth signals, hindering connectivity.

To remove the obstacles, consider the following:

  • Remove items such as computers, Bluetooth/WIFI receivers, microwaves, refrigerators, metal, plaster, concrete, etc. 
  • You could always connect your audio devices elsewhere if you cannot remove these objects. For instance, some people may find removing a refrigerator to accommodate the audio devices senseless.

Connect the Subwoofer to the Soundbar Manually

Another fix is manually connecting the audio devices. Here’s how to do that:

  • Keep the devices must be on. Once they are on, hold down the volume button until a red light illuminates the soundbar.
  • After that, hold down the unmute button for about 3 seconds. The devices will disconnect, and you will know that by the flashing red and green lights. 
  • Unplug the devices and reconnect them after at least a minute.

Enable Soundbar “Pairing Mode”

The pairing mode on an LG soundbar with subwoofer

If your LG subwoofer has a green light but is not working, the “pairing mode” is disabled. To enable “pairing mode” on your LG soundbar, do the following: 

  • Plug it into the power source and turn it on. 
  • Tap on the “function” button on the remote, and you should see a blinking light on the soundbar’s BT icon.
  • After that, the soundbar will switch to pairing mode within 30 seconds. You may need to reset the audio devices if no light blinks on the BT icon.

Factory Reset the Soundbar

Sometimes, your LG soundbar won’t stop blinking green despite following the previous steps. In such a case, performing a factory reset becomes necessary. Though a factory reset may solve the problem, remember it will erase all remembered connections and saved settings.

To do a factory reset: 

  • Turn on your soundbar and hold the buttons “sound effect” and “volume down” for 30 seconds simultaneously. 
  • After that, you should see a flashing light on the E-CLR button, which means the resetting process has begun. 
  • If the LG subwoofer blinks green fast after the reset, it may be time to take it to a repair shop.

Ensure Appropriate Ventilation

Your LG subwoofer may have a blinking green light due to overheating. Overheating occurs when heat gets trapped inside due to a lack of airflow. This problem occurs when the subwoofer is kept in poorly ventilated places such as a cabinet or a corner.

Whatever you do, don’t put your subwoofer in an enclosed place. Instead, please keep it in an open space where airflow can enter. Ensure the open space is dust-free since dust obstructs airflow.
