The first and the most obvious thing to do in this situation is to check the cables and connections.

  • Often faulty cables are the reason why the Soundbar can’t operate properly. And if you find any damage on the cables, it’s better to replace them for your own safety.
  • The cables should be placed in a place where people won’t be able to step on them.
  • Also, check the connections. You have to connect plugged securely.

You can also try changing the audio settings on your TV.

Problem 2: Onn Soundbar Keeps Turning Off

These Soundbars are filled with some unique problems, aren’t they? Well, sometimes the Soundbar works but keeps turning off over and over again. This issue usually happens when the settings of your Soundbar are not adjusted properly.

So, to fix this problem, let’s know about the solution.


If the input is low, your Onn Soundbar will automatically turn off after a while. It occurs when the media is silent, or the volume of your TV isn’t adjusted and is quite low.

So, you need to make sure that your TV delivers powerful signals. You can change the setting manually. Just hold the volume down button and the power button at the same time, and keep pressing them for 10-15 seconds. And that should fix your problem.

If the problem still persists, then check the wires if they are damaged or not. Sometimes, the wires can get damaged, and it’ll affects the performance of the Soundbar. So, if that’s the case, then it’s time to replace the wires.

Also, you can try connecting your sound system to a set-top box. That’ll also ensure a better performance.

Problem 3: Onn Soundbar Won’t Turn On

This is a very common yet frustrating problem that many encounters. This occurs when you press the power-on button of the device. But still, it doesn’t turn on.

It mainly happens when the Soundbar isn’t getting an adequate power supply. Or, it can also happen when the wires are faulty.

So, if you are also facing a similar problem, let’s take a look at the solution.


Firstly, check all the connections. If there are any damaged spots on the cables, then it’s probably the reason you’re facing the problem. Also, make sure that all the connections are securely fastened. Any loose connection will also create problems.

Also, make sure that the Soundbar is indeed receiving enough power from the outlet.

Next, if your Soundbar isn’t turning on using the remote, then the problem might lie within the remote itself. In that case, check the batteries and replace them if needed.

And if it’s still not working, then just use the power button of your soundbar. After doing these steps, your soundbar should be able to operate.

Problem 4: Sounds Are Getting Muffled

Sometimes a strange but common problem can happen. That is: when the sound that is being produced by the Onn Soundbar gets muffled. In most cases, it happens if there is any problem in the connection.

If you are stuck with this issue, let’s look at the solution.


The first thing you can try is to turn up the volume of your Television device. The Soundbar and TV have volume meters that might not be the same. That’s why sometimes, sounds can get muffled if the volume is not adjusted in the right way.

So, you need to turn up the volume of your TV to 100% and adjust your Soundbar accordingly. And that should solve the issue.

And if the problem is occurring due to connection issues, then don’t use HDMI to connect your Soundbar. Rather, you should switch to optical, as these connections usually produce high-quality audio.

In this case, you need to power cycle your entire system, namely your sound and TV system.

To do this, unplug your Soundbar and TV from the power first. Then, you need to unplug all the input connections. This will give the system some time to recover.

After waiting for a couple of minutes, simply plug in all the connections. And your problem should be solved.
