Curved soundbar not working at all

[Stuggies]

Hi just wondering if anyone can help my curved soundbar has stopped working all together. I’m sure a thing flashed up about some update or something but I’m not sure. 
The model number is HW-MS6501/XU. Thanks

Did you manage to get this resolved or are you still having the same issue?
