You might have the wrong source selected. (e.g. you might have your TV set looking for an input from some non-existent external device, rather than from its built-in tuner).
Press the 'Source' button on your remote control. (It's often marked by a rounded rectangle, with an arrow pointing into it). You then need to check that 'TV' (or 'DTV' or similar) is selected. (I suspect that you've got something like 'HDMI1' currently selected).
Also check that the aerial is probably plugged in and that it hasn't been blown off your roof by the wind!
