No Power In Soundbar When Switching On.sony Ct290 Model

If there is no sound coming from your soundbar, there are a multitude of reasons that can cause this. Please try each of the below in turn:

1. Ensure your soundbar is switched on.
2. Ensure the volume is turned up on your soundbar.
3. Try cycling through the sources slowly (waiting 5 seconds on each), to make sure you have the right source selected.
4. Ensure the audio cable is fully inserted into the sockets of your TV and soundbar.
5. If you are using an optical cable, you may also need to change the audio settings to 'External Speaker' or similar on your TV, as televisions can be set to 'TV Speaker' by default.
6. If you are using an AUX/RCA/Phono cable, ensure that you have connected the cables to an Audio Output socket on your TV and not an Audio Input, as they can look very similar.

If none of the above steps resolve your issue, try the below.

1. If you are using the AUX source ensure that your TV/HEADPHONE volume to 80% or higher.
2. If your connected devices have a variable volume, for example Set Top Boxes or Media Players, ensure the volume on these is set to 100%.
3. Try another connection; we recommend connecting via optical. You can see how to do this on our soundbar setup page.
4. Try connecting your soundbar to another TV or device.

Why will my soundbar not turn on?

If the power light is not lighting up at all, reseat the power cable in the back of the device and where it plugs into the wall. To reseat the cable, unplug the power cord from the device, and plug it back in. Make sure it is securely and tightly connected to the device. Do the same in the wall outlet.

Why is my Sony sound bar not working?

Make sure that Control for HDMI or BRAVIA Sync of your TV and audio device is set to ON. Make sure that the ARC feature of your audio device is set to ON or AUTO. Verify that sound is output from the TV after turning on the TV and then the audio device. Make sure that your audio device is set to TV input.
