A:AnswerAny provided STB remote should be programmable with the TV. But only for Pwr/Vol. One caveat with these TCL TVs however is with the input switching. There are no discrete input commands, nor can you toggle through them with the Input button. Input selection brings up a Menu system that must be navigated through with the OEM remote. Only a legacy Harmony remote would be advanced enough to manage this function.

A:AnswerThe Google TV OS is specifically designed for streaming apps. There may be a some random browser on the app store that may technically work. But the UI would be a nightmare to navigate.
