Doing a reset on a Roku device has nothing to do with the remote powering the TV.
Doing a paring button setup on a remote has nothing to do directly with the remote powering the TV.
What I'm about to share is important, and I think a missing bit if knowledge for you.
Roku remotes pair with the Roku device, not to a third party TV. The Roku device does not control the TV.
Roku remotes can be configured to work with different model TVs, but are not "paired" in the sense they are with Roku devices. The Roku remotes control the TV directly, power and volume, without any interaction from the Roku.
When you configure a remote, using the instructions Tivoburkee supplied, you can pick the manufacturer of the TV and it will attempt to load the proper codes to the remote. Sometimes, the first one that Roku tries isn't right. When that happens, you have to use the original TV remote and turn the volume back on, then answer "no" to the screen and go to the next setting.
Do that and let us know what happens. Also, let us know how many different configurations you tried. Trying the same configuration three times doesn't count as three, but one. How many different configurations are you trying?
