The message is coming from your TV and has nothing to do with your remote. It's just telling you what input is selected and the current information of the source. It would help to know the model number of your Roku device written on it somewhere and whether or not you have a voice remote. It sounds like you do have a voice remote since they're the only ones with a power button, but you should know that that button is strictly for the TV. I have to ask the simple question: have you tried new batteries or charging your remote if it's rechargeable?
