I have a US55ES8000 tv and a HW-K450 sound bar. For years, all was fine while connected via an optical cable.
The the tv, sky Q and sound bar turned on and off with a quick press of the power button on the Sky or tv remote.
The optical cable degraded so I replaced it with a new HDMI(ARC) cable. I reconfigured the settings on the tv and soundbar for the HDMI cable.
The sound bar turns off with the power button but will not turn on. I have factory reset the tv and bar but it is just the same. Anynet+ is on on both devices. Any help would be much appreciated.
