Don’t know why is Samsung subwoofer blue light blinking? Continuous blinking could only mean a failure in an attempted connection and in this post you will learn why.

We will go through all possibilities and proven techniques to get your Subwoofer successfully connected.

If your Samsung subwoofer’s LED is glowing in solid blue, it means that the subwoofer has connected successfully to your soundbar device. You will know that the connecting process has failed if the light keeps blinking in blue continuously.

Before closely reviewing how to deal with the issue, let’s take a look at some facts that you should be aware of.

Why Is My Samsung Subwoofer Blinking Blue?

As we’ve just mentioned, there could be two types of blue lights. The one will indicate that the pairing process with your stationary device or soundbar in most cases has been successful.

The other kind of blue light, however, will be continuously blinking. This means that the pairing task hasn’t been fulfilled or your subwoofer is trying to reconnect.

If the blue light is on without any sort of down/uptime, you shouldn’t be worried at all, as the pairing process was successful.

In any other case of blue light, you should take a look at your configuration to check if something’s wrong.

Further in the post, we will take a closer look at both your subwoofer and stationary device.

At this point you cannot know whether your subwoofer or soundbar is responsible for this inconvenience, so we will make sure to inspect both of the devices.

Now that you know what kind of blinking should be alarming, we shall proceed to the troubleshooting part of this guideline.

As unbelievable as it may sound, a simple obstacle might be suppressing your subwoofer from connecting to the main device.

If that device happens to be a soundbar, remember that both devices must have enabled Bluetooth if they are wireless. 

In any other scenario, you will check the cable to see if it is working or not.

When you’re done with the obvious you can start following our steps one by one and hopefully, you will prevent the blue light from continuously blinking.

Step #1 Check If a Stationary Device Is Enabled

If you happen to already connect your subwoofer to a soundbar for instance and during the next launch of the subwoofer the stationary device isn’t enabled, your subwoofer will immediately start blinking in blue.

This will indicate that it is unable to communicate with your soundbar because it is turned off or disabled.

Your device might be “disabled” whenever your device’s wireless or wired abilities are suppressed by an internal feature.

Such a feature could be the power-saving mode or low power mode, but in all cases, your subwoofer will blink if your soundbar is disabled or turned off occasionally.

Better yet, down below we will tell you how to determine whether your soundbar is running and is being active.

How To Check If Soundbar Is Running?

If you can’t tell whether your soundbar is running or not, our best suggestion would be to check for blinking LED lights.

If anything on your soundbar is blinking or is glowing in any color, you will know that the device is up and running.

You could also try to interact with the device, using the remote for instance.

If you don’t happen to have a remote, simply try pressing the power button twice. One to turn the device off, if it is running, and the second time to turn it on again.

If your soundbar happens to be unresponsive to your physical hardware or remote interactions, it may have a hardware problem.

If the case is something internal, such as a hardware problem, your only audible choice is to call someone skilled to take a look.

Step #2 Check If Subwoofer Is Responsive

A common occurrence with subwoofers is that they sometimes become unresponsive to them no matter what kind of interactions.

If it happens to be a hardware problem, but the blue light is still on and you’re not a techy person, pay close attention!

What you can do is try to interact with your subwoofer in any way. The thing you have to do during this step is to make sure that your device is responsive and it isn’t an object of hardware/software damage.

For instance, grab the remote or try to click some of the buttons meant for sound/bass adjustment. If the subwoofer happens to be responsive in any way, you should feel relieved that it isn’t something more complicated.

Step #3 Reboot/Power Reset Subwoofer

A great way to troubleshoot your subwoofer for issues is to firmly reset the device.

For this purpose, we’ve provided you with detailed guidelines about the process.

  1. Turn off your subwoofer and wait for it to cool down to normal temperatures.
  2. Unplug the power adapter of your subwoofer from the power source.
  3. Wait for approximately 5 minutes and plug the power cord in.
  4. Turn on your subwoofer and let it connect if possible.
Note: A top suggestion is to plug the power cord directly into a wall outlet to avoid possible complications with the power strip/divider if you are using one.

To perform a simple reset of your subwoofer that does not contain any power adjustment, simply hold the power and the volume button simultaneously.

Step #4 Update The Main Unit

If the subwoofer keeps failing all of its connection attempts all the way to this point, your main unit might be missing some important updates.

However, the thing you have to do here is to make sure that your soundbar or any kind of stationary device your subwoofer is using as the main unit is updated to its latest version.

With the new firmware, there are plenty of innovative implements which can be crucial to your subwoofer’s performance. Some of them even include important drivers your subwoofer can’t connect without.

Step #5 Change Audio Format

If you’re still reading this, it means that nothing has helped you to fix the Samsung subwoofer blue light blinking problem.

Changing the audio format seems to have stopped the blue blinking light for some users so we’ve decided to include it.

If your subwoofer can not connect to the soundbar, try changing the audio format to see if that will help.

Maybe your subwoofer isn’t compatible with the voice your TV is configured to broadcast, so changing the audio format should make a difference.

To change the audio format, visit Settings > Audio > Audio Format, and try with each option to see which one is going to perform best.

To wrap the topic up, sometimes not being able to connect your subwoofer is really frustrating. Even though you tried restarting, updating the main unit, and even changing the audio format of your TV, maybe it is just related to hardware issues you cannot compete with.
