I use a Roku Express 4k+ with the factory remote that was provided.
Through the Rokus setup process the remote is successfully paired with my Sony Bravia XR-55X90J television.
If the TV is off/idle and I pick up the Roku remote and press “Power” nothing will happen. If I then press “Power” a second time it will turn the TV on and to the Home Screen of my TV. If I then press “Home” it will take me to the Roku Home Screen.
Now separately from the above, if I were to use the provided Sony TV remote and press “Power” it will immediately turn the TV on. I can then select the Roku input to go to the Roku Home Screen.
Thirdly, if I were to use my iPhone with the Roku application which is connected to my Roku express 4k+, pull up the remote and press any button at all it will immediately turn on my TV and go to the Roku Home Screen.
So my question is why do I have to press “power” on the Roku remote multiple times just to turn the TV on and is there a way to change it?
I wonder: If you press Home on the Roku remote (with the TV off) does that turn the TV on and set it to the Roku input all in one step? It used to work that way for me. (Until I turned off the HDMI-CEC because I didn't like that, but it may work well for you.)
In addition the the above possible workaround, perhaps a different Sony code would work better for you. I'm honestly not sure what kind of code mismatch would consistently provide a power on only on the second time, so I'm just guessing. I'm thinking that some TVs offer discrete on and off codes, and there could be some conflict if the TV sees an HDMI-CEC command and an IR command around the same time, but I can't quite figure it out.
Oh, I assume the remote is aimed at the TV both times, right? I could imagine: you press the power with the remote sitting on the sofa, and nothing happens, so then you pick it up and point it better. Just grasping at straws...
1: I will test this out a few times and post a reply afterwards.
2: The automated setup process configured the remote to IR. I have not tried switching in to CEC.
The provided Sony remote communicates to the TV in a couple of different ways.
3: My Sony remote does not need to be pointed at the TV. The Roku remote during operation does not appear to necessitate being pointed towards the TV either. However to answer your question yes I do in fact point the Roku remote at the TV during any and all inputs, including the initial attempt to power the TV on. I have the Roku Express 4k+ as well as the TV placed in such away that the remote shouldn’t have any issue communicating with whichever receiver. All devices in question are kept clean, positioned to avoid any readily apparent interference, absent of any other reflective surfaces.
Okay so I tried pressing the “Home” button instead of the “Power” button after allowing plenty of time for the TV and Roku to be powered off and idle.
Interestingly enough, the TV immediately powered on and automatically switched from the TV start page to the Roku. I do however have the TV settings to recall to the last used input which could account for the switching.
This will work as a solution for me though to not have to press “Power” more than once to get the TV on. Thank you for your reply!
Just to expand on @Strega2 reply to you, Roku uses the HDMI CEC feature "1-touch play" that when you press the Home button (or any other button on the Roku remote other than power and volume) will simultaneously wake the Roku device, turn on the TV, switch to the HDMI port the Roku device is connected to, and you should find yourself on the Roku Home Screen.
For this feature to work, just have to have your TV's HDMI CEC enabled, and then enable 1-touch play through Roku Settings/System/Control other Devices/1-touch play
Will still need to use Home button to return to Home Screen after your streaming session to stop streaming/using data, and then press Power to turn off TV.
The power and volume buttons (TV controls) on the Roku remote are IR-based so need to point that at TV to work. The Roku remote (Voice Remote that accompanies your device) then communicates with the Roku device via RF/wifi so does not have to be pointed at device. (can even tuck/hide the device out of sight if wanted).
