When I put my Apple TV 4K to sleep manually, the white status light turns off then back on about 5 seconds later and stays on. Only the status light on the Apple TV turns on; TV does not power back on. Don’t think this is an HDMI-CEC issue because when I sleep my ATV, TV also goes to sleep; when I wake my ATV manually, TV turns on too. Any thoughts as to why the status light turns back on when I put ATV to sleep?
 
Mine does the same thing. I have had nothing but weird issues with this device since I got it. I think that most of it is software related.

I have one issue where it will start prompting me for my password and then cycle over and over. The problem is that it sends it to my phone as well and I have been unable to find out how to unpair my ATV from my phone. I had to turn my phone off.
 
To fix the Apple TV light coming back on, I unplugged mine for 15 seconds and replugged. If by password, you mean the devices are asking for your Apple ID password, I signed out of iCloud and back in to fix that. Buggy IOS 11!

I'll give those a shot. I have reset the device several times trying to get it to calm down. I even turned off CEC on my tv, but then I lost sound randomly and could never get it to come back. This OS is very buggy.
 
Tried unplugging power as well as using a different HDMI cord but status light still turns back on right after I put ATV to sleep.
 
Interesting: I connected my Apple TV to a different TV and to a different wireless network and I’m no longer having the issue. Apple TV stays in sleep mode and the status light does not turn on. The TVs are very similar Samsung models with the same settings enabled. Is there any way that the wireless network/router could be making a difference? I was using Google Wifi in the original setup where the issue was occurring.
 
I too was having exactly the same problem with the ATV waking after a few seconds of being put to sleep and the white LED staying on. As far as I can tell it is an issue with certain TV's. I have 3 ATV's (1x ATV 4th gen & 2x ATV 4K's). All my ATV's don't have this problem on my LG and Sony TV's. But they all have the staying awake problem on my Samsung TV. All the TV's I have are 2016/2017 models and have HDMI-CEC enabled. How I corrected the problem on my Samsung TV was to turn off the Samsung universal remote setting which allows the Samsung TV remote to control external devices. After turning this setting off the ATV slept properly and the problem has not happened again.

Is there a way to do this without turning off HDMI-CEC on the Samsung? I still want my TV to go to sleep when I put Apple TV to sleep, like it does currently.
 
I don't turn off HDMI-CEC. Depending on what Samsung TV you use, on the newest Samsung Tizen OS when you press the home button a tab will come up across all the bottom of the screen. You then go to Source, then up to Universal Remote and then delete the Apple TV if it is an option.

Awesome, that fixed the problem! Thank you so much.

It has nothing to do with it. This is the fix. Works like a charm. You still will be able to turn on and off your TV with your Apple TV.
Do not turn off your HDMI-CEC just make sure your tv controller can’t control your Apple TV.

I have been having this problem for a while for a few months, after I bought a new 2017 Samsung tv. I even just upgraded from a atv 4 to atv 4K and the problem persists.
From what I have read online, it appears to be Samsung TVs and their remotes. People suggest disconnecting the Samsung remote and only using the atv remote. But I would prefer the opposite and only use the tv remote. It is pretty simple and does everything I need on the tv, atv and DVD player. Plus!, I have young kids and would rather they use the tv control instead of the smaller atv control.
So what I am asking is if anyone found a fix to this issue that allows you to keep using the tv remote as the main remote.
Thanks,
RJ

Do you have a similar fix for the LG TVs? I have a 2017 C7 OLED and have the same problem you described with the aTV not sleeping properly and then turning the LG TV back on. Half the time both devices sleep fine when pressing sleep on the aTV remote, the other half they both wake up and I have to use the LG TV remote to turn the TV back off.

Hey, sorry I don't. I have an LG B7 OLED and don't have the issue on mine. So I'm not sure what could be causing it.
 
In my experience with Apple TVs - which goes all the way back to the super-heated original units - they have all, always, simply refused to stay turned off. At least the current models don't contribute to global warming the way the first ones did, but it's still ridiculous and annoying.

For the record, I don't even use the ATV remote; that's put away in a drawer somewhere long drained of juice, so it's not the remote. I can only think that it is something on the network that triggers them to wake up at the slightest provocation. They're like the dog in "Up" when it sees a squirrel.

As weird as it may sound - this really does not happen to me. I am not keeping watch overnight, so even if it woke up sometime at night, they are all nicely asleep by the morning when I check them.
PS there was a problem with android TV firmware, but Sony solved it in one of their previous releases.

@Akerhage - it does not matter, to which HDMi you have connected what. CEC is a common wire across all of them. Are you sure it is not your computer? Although, I admit, most computer HDMI ports do not have CEC.
The only way to discover the wakeup reason is to disconnect devices one by one and observe the behaviour. Or buy a CEC bus snooper.
Also - how many CEC devices you have connected in total? In my setup, I saw aTV become in conflict with my Arris IPTV box, so I had to cut the CEC wire on Arris to recover control. I don't remember it creating wakeup problems, though.
