VIZIO Subwoofer Not Working – Fixes

Without a subwoofer, you cannot enjoy the throttle, and the low-frequency response, which is a critical factor in the sound. Fixing the subwoofer which is not pairing, or not working with the soundbar requires different steps. 

Below, we have provided you with all the steps that you need to follow to fix the VIZIO subwoofer not working issue.

1. Check the Power

Firstly, you will have to ensure that your subwoofer is connected to the power, and is turned on. Often, we make the mistake of not powering the soundbar and wonder why the soundbar is not working.

So, before moving into the crucial, and technical steps, you have to simply check the power connection. If the subwoofer is not turning on, then you need to check the power cable. If it is good, then move on to the next steps.

2. Reduce the Distance Between the Subwoofer & Soundbar

If there is a Bluetooth connection between the subwoofer and the soundbar, and you have placed the soundbar, and the subwoofer far away, both of these devices will surely not work, as the Bluetooth comes with a specific range, and after the devices get out of the range, it does not work.

So, you will need to assure the distance between the subwoofer, and the soundbar is not very far away. If it is so, then you need to get them closer to each other.

3. Unpair & Repair the Sound & the Subwoofer

Nextly, you need to unpair, and then repair the soundbar, and the subwoofer using Bluetooth connectivity. So, if there was an issue in the connectivity, it can be resolved by this simple trick.

  • First of all, you will need to reboot the soundbar and the subwoofer.
  • Afterward, press, and hold the pairing button on the subwoofer, until you see the lights flashing on the soundbar.
