XI5 remote not powering off TV once I add my sound device

[cozmr21]

I have a LG 75NANO90UNA 75" 2020 model TV. Have a 4K X1 DVR and Sony surround sound system. HDMI to TV and optical from TV to my Sony. When I set up my remote I get the TV to work with volume and power. Next step is to add a sound system. I add my Sony surround sound (takes about 5 different codes before it response). Once I add the Sony system the power button on remote only powers off the sound system. TV does not respond. The Comcast remote is able to change inputs on the TV.  

I have done a compete reset of box. I also done a reset of the remote. I have replaced the remote. Same issue each time. Frustrating using 2 remotes. Please help

if you can not find a different code to try for the Sony and you are following the steps as presented on the screen after pressing the A button then the remote is not going to work for your current configuration. Is your Sony a fairly old unit that does not have ARC (audio return path)?

I would recommend to try to disable HDMI-CEC feature, which can be found here:
Settings -> Device Settings ->  Power Preferences -> HDMI-CEC.
Please, let us know if it didn't help

I have tried other codes, both for the LG and for Sony. The Sony is an old unit, but the comcast remote has worked correctly for 2 other TVs. Powering off both units.

Still the same issue. Looking at other post I see this problem pops up with other brand TVs and sound systems. Still looking for a solution. Would a different model remote work better?

Please, confirm that disabling of HDMI-CEC didn't help here.

Settings -> Device Settings ->  Power Preferences -> HDMI-CEC

It did not help

So I'm I stuck using 2 remotes?

I think the problem might be how LG tv and RF signal. Can my remote send a RF for the TV and IR for the sound together? I paired an older xfinity remote and got a different response. The older remote was only able to turn on and off the tv with the tv button no the main button. The sound system was not able to turn on even though the set up process it worked. This is a new model LG tv with RF. 

Still looking for answers. @ComcastDenys

I have an old Sony surround system with blue ray player built in. My youngest son set up all the connections so basically all sound plays thru the Sony sound system. We use a Harmony One Remote. It seems to work seamlessly most of the time. At one point a Comcast tech came for a service call and he set up the X1 remote to control the sound system. It works sometimes. The thing is if we watch a blue ray disc the Sony system stays on DVD input. So we went back to using  the Harmony remote where everything works better. I hate to recommend you spend more money but it kept our confusion down.  My only glitch is that Harmony remotes need programmed online so you need to download a third party app from the Logitech website, which is fine if you use Windows OS but I use Mac OS and Apple doesn't support 32 bit apps any longer. Logitech did send me the 64 bit software but I haven't installed it on my new Mac since my Harmony remote is set up and working fine. Using two remotes can be confusing, so I created a Word document that lists the steps and inputs in order. The only thing I can add is that my Harmony One is more user friendly than the X 1 remote. It has a touchscreen that lists "watch tv" "watch a dvd" "play a music cd" etc. the channels and volume buttoms are located in a place that's easy to locate and the pause/playback buttons are easy to locate as well. Sorry for the long post.
