When the sound from your LG subwoofer suddenly stops, one of the most common and obvious causes is that there is too much Bluetooth interference happening around it. When you got to that point, your subwoofer was presumably already linked to a device via Bluetooth.

Problems with the power supply are another typical cause of a subwoofer’s failure to function properly. It is possible for the subwoofer to stop working if it is not receiving enough amount of power.

Reason 4 – Damaged subwoofer

Now, this particular factor is pretty clear-cut evidence of why that issue exists. Any sort of physical damage that your subwoofer sustains may have an effect on the components that are contained therein. which, in the end, may result in troubles for the subwoofer.

In this case, though, we’ll need to use our wits, as the issue is typically associated with the Soundbar and not the Subwoofer.
