By default, some HDMI devices are set to turn the TV on when they turn on. This feature is Anynet+, also known as HDMI-CEC, and allows you to control both devices with your TV remote. If you want to turn on your devices separately, you can turn off Anynet+ in Settings > General > External Device Manager, but you will no longer be able to use your TV remote for both devices.
Unplug the TV for 30 seconds.
Unplug the TV from the wall outlet or surge protector for 30 seconds, and then plug it back in.
Try to update the software.
In some cases, a software update can correct the problem. There is a risk, however. If the TV turns off during the software update, it could damage the TV. Updates can take up to 30 minutes depending on network speed, so if the TV is not turning off too frequently, try updating the software.
Disable the Power On with Mobile option.
TVs that can connect to SmartThings can be turned on using compatible devices, sometimes automatically. However, if abnormal "power on" signals are sent through the wireless network, they will trigger this function and make the TV turn on.
If you do not want this function, navigate to Settings > General > Network > Expert Settings > Power On with Mobile, and turn the setting off.

But this is not a solution as it's written. You are simply telling us one possible reason why it's automatically turning on. Are you suggesting that people disable those two options? What are the impacts of disabling those options? Please explain this in your solution. Thanks.
And how do we shut off this "feature"? I don't know what HDMI-CEC or Anynet+ is, I just know this TV should not be turning on after my family goes to bed. It's wasting electricity and the life of the TV. I have the latest update. I do not have a cable box, but do have a firestick and OTA antenna. I use the Firestick's remove to turn off the Firestick and TV at the same time, so I have no idea what signal the TV could be receiving to turn on. I just want to know how to turn off this feature. The TV is outsmarting itself apparently....
You can disable the Anynet+ by going to Settings>General>External Device Manager>Anynet+ (HDMI-CEC) and turn the feature off.
So with this not being a solution, is there any other suggestion for this issue? My TV is almost 6 months old now and it seems as though it's becoming more frequent that this "turning itself on after being turned off" issue is happening?
This was an expensive tv to buy. Is this something I need to claim under my first year manufacture warrenty? Would be extremely disapointing for something to happen to my tv...
If you don't know what HDMI-CEC is, then Google is a good place to start. Basically it allows devices connected via HDMI to control each other in a limited way. Thus, a cable tv box can turn a tv on.
