Re: How do I switch from Roku back to Spectrum cable?
Is this an actual TV (not just something plugged into her TV)? If it's an actual RokuTV there should be a tile(s) to select HDMI inputs. If there isn't, go through the Settings. I can't remember exactly where it is, but somewhere you can add inputs to the Home Screen and even name them.
