I have an almost 10 yr old Sony google tv and I bought a Roku stick. When I plug it in, I can see Roku as an input option but either my tv or my remote (not sure which), won't let me change the input to HDMI/Roku. Any ideas to use it on that tv? We are trying to get rid of cable altogether in our house. I have a Firestick on another tv and it did the same thing.
