Is it a standalone box? I had the same problem at one point, and I found out it was a combination of the CEC settings and the YouTube app. I was able to fix it by exiting the YouTube channel before turning off the TV.
If that doesn't work, or isn't your problem, you can disable CEC in the settings. Good luck!

In fact, if you have a stand alone unit, it's a good idea to exit WHATEVER channel you are watching and return to the Roku home screen before turning off the TV. This assures that the Roku doesn't continue to stream in the background and use up your data limit (if your ISP applies one).
(I don't know if a tv with built in Roku streams in the background when the tv is off.)
I've been away for a couple of weeks. Last night we didn't go to YouTube at all. We watched a movie on Amazon, and the TV automatically came on again and went to the RUKU channel using our source/input function.
One of the first posts indicated that I should turn off the CEC function. I don't know what that is or where to find it. Any help to find that or any additional thoughts would be appreciated.
Thanks Frank Wagner
@FrankJWagner Thanks for the note here.
CEC will need to be disabled in your TV's settings. On your Roku device, try turning off '1-touch play' in Settings> System>Control other devices. That should help.
I have found a similar problem... but it is related to my cellphone not my remote. I have the roku application on my phone. The application is not running in the background that I can tell. When I am on the phone near the TV and I end the call the TV comes on. I am using a Roku sound bar. I thought it was the remote at first but the pattern is definitely clear it is my cellphone. I have a Samsung Note 10. I didn't see anything posted like this anywhere and this might be everyone else's issue too thinking it is the remote.
I figured out that even though I had closed the app and removed it from memory by the close all apps function, Roku was still running in the background. I had to go to the app in my settings and force a stop. This released the app from my phone and stopped turning on my TV.
