I have a brand new Samsung QE55Q80B TV connected to my old Samsung HW-H550 soundbar. All worked fine for a few days but now when I turn off the TV, the soundbar turns off (as it should) but immediately turns back on again (with the TV still off).
I've un-paired and re-paired the soundbar several times, re-set the soundbar (holding Play/Pause in the power off mode), unplugged both soundbar and TV from the mains etc but to no avail.
If I turn the Bluetooth Power setting on the soundbar to off, it solves the problem, but then of course I have to manually turn on the soundbar when I turn on the TV.
I can't understand why this was working fine, and now it isn't when nothing was changed in any of the settings?
