A:Answer When you were setting up the TV for the first time, it asks what kind of input you were setting it up for. You might have selected a different input than you intended.
(*A note: even if you're using an antenna, all stations currently broadcast in digital. Analog TV broadcasting has been discontinued.)
To access your setup, use your remote, press "Menu" then select "Help" in the upper right hand of the box, then select "Customize my TV" and it will allow you to select to restart the Easy Setup wizard if you wish to make sure you made the proper signal input selection upon setup. Good luck.
