Analogue or Digital set ups

[TAFFE]

I have recently purchased a Sony 32 inch LCD digital TV ( KDL 32D3000 ).

I have digital Sky+ and am trying to tune the channels, but....

I seem to be able to set the channels up in analogue but when i try to do Digital set up, it tells me no channels are available ??

Has anyone else come across this and solved it, am i being a complete bonehead, or can anyone help !

Thanks in advance

the very first thing you need to know, is do you have a DVB-T transmitter in your area, and are you pointing your external tv arial at it....
