What channel should this TV be on to play the apps? No cable or anything.

Also, input should be on TV, right?

You are going to need to "educate" your TV since it isn't "smart".
Connect a media streamer to it. Many options. Apple TV, Roku, Chromecast, Firestick, computer, or android TV box. Take your pick.
If you already have one then select the input on the TV you connected it to. TV usually refers to the coax antenna input.
