I'm very sorry to hear that has happened. In order for me to help you most accurately, please provide the complete model code for this device. Also, how do you have the soundbar connected to the TV?
I have a UN60F6300 smart tv. When watching a Netflix movie the sound turns off for a split second and resumes. It happens about every minute or so. I had no such problem when watching through my Samsung Blueray player. Any suggestions?
