samsung subwoofer blue light on but no sound

Samsung subwoofer is a popular choice among music lovers. It is handy, and many people find it easy to handle and navigate the Samsung subwoofer. The blue indicator light of the device helps to determine that the subwoofer is connected properly.

If your Samsung subwoofer’s blue light is on, but there is no sound, today’s blog post will help you to solve this problem. We have listed all the potential causes behind this issue. And also, you will find the best advice to fix the subwoofer quickly.

What does Samsung Subwoofer’s Blue Light Mean?

The blue LED light on your Samsung subwoofer indicates that the subwoofer is completely connected to its audio source, such as your TV.

When you connect the subwoofer to the source, the light starts to blink for a while until the devices are fully connected. After they have connected, there will be solid blue light.

The light can be located on the top or the bottom of your subwoofer according to the specific model.

Although this light is visible, there are some internal and external issues that interrupt the production of sounds.

What Causes ‘Samsung subwoofer blue light on but no sound?’

If your subwoofer does not provide any sound, although the blue light flashes, one of these things can be the cause.

  1. Incorrect Audio Input – If you have connected the subwoofer to the TV using the wrong output, this fault can happen. You should confirm that the audio signals are manipulated through your subwoofer. In case the audio track has not been transmitted to the device, it cannot provide sound.
  2. Faulty Audio Cables – when there are damaged or loose cables, the device cannot provide proper sounds. The cables between the subwoofer and audio output should be tightened well. If there are any damages like scratches, there will not be sound transmission too.
  3. Incorrect Power Connection – You need to make the subwoofer’s power connection secure. You can use a separate source or an outlet for this. Either way, you have to verify that the outlet can function without interruption. If the subwoofer loses power, the light will still flash, but no sound.
  4. Audio Source Configuration – the issue can exist in the settings of your audio source, too. You need to verify that the subwoofer’s output is active. Make sure to check whether the output has not been muted. In some audio sources, there are special settings for subwoofers, so check your manual and make adjustments.
  5. Internal Subwoofer Issues – Sometimes, the internal parts of your subwoofer might have some damage. For example, when there is a faulty speaker driver, you will not hear any sound, even though you have adjusted all the settings correctly.
