Since we switched to a fully digital service in Telford and Wrekin neither of my 2 Samsung TVs will pick up the transmitter and i cannot therefore re-tune........... I've tried via different aerials including a loft based one. My Sony and my brother's Samsung, in the same house are ok and have re-tuned fine. Will I have to buy a set top box or is there some way i can force it to pick up the transmitter? The option is greyed out and the remote just by-passes it (even tried my brother's remote - same thing).
