Finally, exit the settings, and your TV should now be in DTV mode.

To change from DTV to ATV on your Samsung LE32C350 TV, press the "Menu" button on your remote. Navigate to the "Broadcasting" section, then select "Antenna" or "Source" to switch between DTV (Digital TV) and ATV (Analog TV). If there's a direct "Source" button on your remote, you can also use that to toggle between available inputs. Once you've made your selection, exit the menu to start watching.
