I started having this same problem after the soundbar got unplugged while it was still powered on. I can connect my cell phone bluetooth to it and play music or sound through soundbar and subwoofer but none of the LED lights on the soundbar work and none of the buttons seem to do anything no volume controls, no input selection, no mute. I do hear an electronic popping sound when it powers off but other than the bluetooth sound from my cell phone nothing else works.
