I'm sorry to hear this. You could check to see if the unit is in need of a firmware update.
If this doesn't work the unit may require service. Just reach out to us via e-mail at email@example.com
Up until this weekend everything worked fine. I use this sound bar for my Samsung TV using Anynet+ and connected to the ARC HDMI on the TV. I also use it to connect to my phone via bluetooth. Nothing works now. When I turn on the sound bar the display stays on "WAIT" then shuts off by itself. It will not output any audio from the TV and I can't connect via bluetooth. What happened?
