My DVD hookup

Solution
The TV may not let you select the input you connected the DVD to unless the DVD is on.
If there is a button on the remote labeled "input", "source" or "TV/Video" try that.
You may have to select it from the onscreen display. The owners manual should help.
Well depends on your smart tv. But typically it'll have a button on the remote saying something like smart or menu. If you press it it should show you some sort of view with apps. Which tv is it?
