Roku mobile app

[JTRSwiss]

I just bought a TCL qm850g. I hooked up my Roku stream bar Pro. When the TV is on I can navigate with the Roku app with no problem. The only thing the Roku app doesn't do anymore is turn on the TV when I hit one of the streaming services on the Roku app and does not shut off when I use the Roku app microphone to shut the TV off which all worked perfectly fine with my Samsung Neo QLED.
When I hit one of the streaming services a little white light blinks briefly on the Roku bar but TV does not turn on.

Also, when I navigate within the Roku bar settings there is no Power option whereas some people suggest to enable "quick startup".

I'm disabled and cannot operate the regular Roku remote but the Roku app is easy to navigate for me. Any help, thanks!

Problem solved! TCL got back to me and told me to do the following.

First, please ensure that the Roku Stream Bar Pro is connected to your TV's HDMI Arc input and that the CEC feature is enabled on your device.

Once enabled, follow the steps below:

a. Go to settings.

b. Go to channels and inputs.

c. Go to external device control.

d. Enable the following: power the TV on sync, device standby in sync, HDMI control.

Once enabled, try turning the TV on and off using your Roku remote and check if the same issue persists.

Note, it works on all 4 HDMI's.

You will have to turn on/off the TV by using the Roku app microphone. I used to be able just to hit any of the streaming services within the Roku app and the TV would turn on. No big deal, this is working for me.

Now, it just would be nice if there also would be a power button on the Roku app. Just a suggestion so we don't have to use the microphone every time.
