i have added a new tuner to my VU DUO 2.
I was using 2 twin sat tuners , but i wanted to use a cable instead if using a sat dish to watch and record FTA channels.

I have installed the tuner , but i cannot get it to pick up any channels when connected to the cable socket.

not wanting any other channels , just FTA.

I have both tuner c and d to DVB-c and i have set the net id to the correct one for my area.
Ive used RG6 cable and attached one end to the input on the tuner and the other to the white cable box on wall ( tv socket / not fm )

i cannot get a signal or any channels when doing a ABM scan..
PS it is a genuine tuner from WOS.

Any ideas . or pointers? ( hoping it isn't a faulty tuner )
Thanks in advance..
