Soundbar has no power.

Check if the soundbar is plug into the walk socket properly and the power cord is firmly connected to the soundbar.

1 Unplug soundbar from wall socket.

Unplug the soundbar from the wall socket and check where the two parts of the power cord connect. 

Your power cord actually comes in two parts and it is this connection between them that is most likely to be forgotten about. Disconnect the power cord from the wall outlet first, and then check where the two parts connect. Be sure to connect them firmly; they should not easily disconnect.

2 Wall socket test.

Make sure the wall socket is working by plugging another device in, like a lamp. 

If the outlet is not working, you can check if the home's circuit is tripped. Otherwise, contact an electrician for further assistance.

3 Check the power cord connection.

Make sure the power cord on the back of the soundbar is firmly connected to the soundbar. There should not be any gaps and it should not disconnect easily.

4 Plug the soundbar into the wall socket and turn it on.

If the soundbar still didn't turn on, please visit our Samsung service locations, or call our contact center for any further assistance.

- Make sure your TV is set to use external speakers

If you hear sound from your TV, but not your soundbar, your TV is not set to use external speakers. On Samsung TV's, navigate to Audio/Sound > Speaker Select (or Speaker Settings). 

Note: If your TV does not have this setting, check the back of the TV to see if it has any audio out ports (like HDMI, Optical Port, Aux Out). If it does not, then your TV does not support external sound systems.  

- Set the source for the soundbar

Use the source button to adjust the source to how the TV is connected. The front display on the soundbar will show the currently selected source from one of these options:

  • HDMI
  • D-IN/Optical Audio
  • AUX
  • Bluetooth

Make sure the cable is securely plugged in at both ends and check if audio works. If there is still no audio, replace the cable and try again.
