Why Does The LG Subwoofer Blinking Green Light? 4 Crucial Reasons!
We could identify a total of 4 reasons for the green light blinking and all can be the cause! However, get a look at what the light indicator actually means before you learn about the reasons:

Connection Problem Between LG Subwoofer and The Soundbar
One of the common causes of a blinking green light on the LG subwoofer is a connection problem.
When the subwoofer is turned on and is in a state where it is not receiving a signal from any other device, the blinking green light appears.
This connection problem can be due to faulty cables if you’re connecting the devices via wires. Or, there could be Bluetooth connectivity issues if you’re pairing wirelessly with other devices.
Power Supply Issue
Then the next thing to which you need to pay attention is the inefficient power supply.
It can also trigger a blinking green light on the LG subwoofer, indicating that the device is not paired up with any other device or does not have proper power to get connected.
Now what can be the possible cause of having a Power supply issue? The reasons can be defective power cords, faulty cables, and any other wiring issues that will require further inspection.
Faulty Motherboard/PCB
The one reason that many forget to consider is the motherboard issue! We have learned from forum users that LG subwoofers from previous generations have faulty motherboard designs. The early designs did have some major issues with the PCB and that’s why the problem was so rampant.
Long Distance between Devices
Last but not least, When the soundbar and subwoofer are placed too far apart, they may have difficulty pairing properly.
This can result in a problem in connecting these devices, and as a result, the green light starts to blink on the LG subwoofer. Sometimes, the distance can also cause your LG soundbar to change inputs!
So basically, when the LG Subwoofer is free and is ready to pair up, then it starts to blink green.
To resolve these problems, we are recommending some best tips and tricks in the next section!
