Ok. I have 2 TCL Roku TV's about 50-60 feet apart and the other TV keeps changing the inputs on mine. How do I reprogram the remote to a new frequency to stop this?
You can't if the original Roku tv remotes are IR only. There is no second IR code address available. But what you can do is switch both tv's to wifi voice remote, a Roku wifi remote will only control one Roku device at a time. Both Roku tv remotes have to be replaced!!!
