I have a new Panasonic 42inch plasma TV and I am not happy with reception. I had new aerial system, top of range with booster for other room use. The signal breaks up on some channels( crack noise on sound / horizontal bands of picture distortion). Loss sometimes entirely of channels like FILM4. The areial system has been checked OK. The separate freeview box running a TV in another room appears OK. We are on Wrekin transmitter. Any suggestions please. Thanks.
