How can I control my LG OLED TV and Bose V35 with my remote

I've tried pairing the remote with the TV and Bose but it doesn't work.  I've tried the onscreen system and pressing Xfinity and Mute, waiting for the green light and entering the code. 

I can get the volume and power to work but only if I point it at the Bose which is behind the couch in a cabinet.  Volume/mute work then but if I click power, I get a Bose created screen that says Cable, DVD at the top and FInish turning off, Turn system back on at the bottom.  No buttons allow me to select anything so I can't really turn the power off that way.
