My TCL tv with built-in Roku keeps turning on by itself after we turn it off with the Roku app, this happens 2 or 3 times before it stops doing it. Has anyone experienced this? if you found a solution pls let me know.
We have the same issue. We live in an apartment where there is a line of sight to another apartment building out our living room window, so my theory is that somebody else with the same kind of remote in the other building can turn our TV on, whether intentionally or unintentionally. Short of covering the IR receiver and only using he phone app to control the TV, I'm not sure what the solution is -- IR remotes are all the same, there is no way to pair the remote and the TV so that only our remote can turn it off and on.
I have found the app turns on the tv just by opening the app. It turns on whichever tv we last connected to via the app. This is very annoying if I want to control a different tv than the one I last connected to.
