RC73B REMOTE PAIRING WITH A LG TV-OLED55C1AUB/ DENON RECEIVER-AVR-2700H

What is the receiver model? Rerun Remote Setup but instead start with programming just the LG TV. You may have to mess around with several codes to get the right one that controls input, power, and volume. Once paired, go along to pair the remote with the Denon receiver. 

What ‘three’ things are you trying to sync? You only listed two, the Denon Receiver and the LG TV.

I sure I put my receiver model Denon AVR -2700h  please only respond if you know what your talking about please  the one mistake I made in the three items is I’m syncing a Denon receiver AVR-x2700h and a lg tv oled55c1aub  and a DIRECTV dvr hr5400-700 and using a DIRECTV rc73b remote and in remote setting the lg tv is listed with one code and the Denon receiver is listed but will not sync  and also I already synced my lg tv but that remote will not turn or off the Denon receiver  but the remote does control the volume from the Denon receiver 

I need a code that’s works I already attempted codes I looked up but none will let the remote control the on/off feature of the rc73b remote control  as posted in my first post it works with my setup in another room except my DIRECTV item is genie mini c61-700 and my tv is Sony-xbr-43x830c and the remote in that situation turns on/off all the the receiver is the same Denon AVR-x2700h
