My UE50TU7005 turns on randomly. no soundbar or similar connected. anybody else seeing these problems on Tizen TVs?
Could we take the current software version of your TV? Go to Home > Settings > Support > About This TV.
Also, check to see if any 'timers' are active on your TV, go to Home > Settings > General > System Manager > Time > Off timer.
I had the same issue yesterday (same model nr.)
After turning off, it went on again after 30-60sec. (at least 5 times) A bit scarry when you sleep....
Only way to stop is was by completly remove the power to the TV.
I figured out, that as my TV was connected to the router it was receiving Wake on Lan packages from the network. I turned WOL of on the TV and the problem has gone now.
