You can go to a walmart, there they have Roku voice wifi remote, once paired will work with all roku tv's. They also sell the One-For-All urc-7935, which works great with roku tv's. Use section D in the instructions and use the TCL roku tv steps. If you don't need Vudu or you tube keys, using the insignia roku tv directions would get you Slingtv and Google Play commands instead.
