I just bought a Samsung Q70R QLED TV and on the second day it turned on by itself after being turned off for ~2 minutes. It did it again today.
I see that this is a recurring issue for several models. Can someone from Samsung please contact me so I can get this figured out?
Solved! Go to Solution.
The TV will only power on by itself when HDMI-CEC or Anynet+ is enabled and a connected device is sending a signal to the TV. The TV receives this signal and powers on. Most likely culprits are a cable box or satellite box, but can also happen with connected sound systems or blu-ray players.
I have the same tv and having same problem. The past 2 nights before bed I turned the tv off. About 30 seconds - 1 minute later the tv turned back on by itself. I then turned it off again and it stayed off. No idea what the problem is. The tv is only 5 days old! Have updated to the latest software on the tv.

I also noticed when it comes back on 30 seconds or so after turning on, that the QLED Samsung logo pops up. It's as if when I turn on the TV, it's doing a full system restart and coming back on. Only seems to be doing this late at night. Doesn't seem to come back on when turn off during the day.
