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.
Try Settings/System/Control other devices.... make sure one touch play is disabled.
Oh @Tivoburkee is the one you should be talking to.
maybe he knows how to switch bands or something. Probably does.
Remember Roku doesnt make the TV's TCL does.
you could contact them.
I think TCL used to be RCA I forget.
Why dont you use an Aquarium screensaver?
Solid State doesnt really wear out.
After you change Settings sometimes you need to do a System Reset.
Same issue here with the App and TCL Ruko TV. This last time, I turned off the TV and then made sure the app was closed on my cell phone. It seems to have worked, I have waited about 10 minutes now. I allowed my cell to go to sleep and then woke it up again, still no TV on!
I will have to remember this is the future, Thanks to all of you for the ideas!
I've notice that the app can control multiple devices, but switching to one not currently selected will turn it on as a side effect. This can be surprising if you stop watching in a different room and switch control back to the one you watch more often before closing the app.
