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
