I have a Phillips roku tv and the remote is broken but even worse than that I cannot even use the roku app to control the tv as we switched service providers and I have a different WiFi how can I fix this?
Even remotes twenty years old would work on the philips roku tv, which uses a very old tv code set. Do you have any old universal remotes in the house, if so name the brand and model number I could probably find a working code for it. Cable and other oem remotes that can be programmed for tv's would work.
Lacking a remote, the only thing I can think of to try is if you can change the setup on your router to have it use the same network name (i.e. SSID) and password as your former router that your tv knows how to connect to.
