I've had Freeview for over 2 years now (using a Sony IDTV) with no reception problems at all. However, over the last few weeks I have been experiencing problems with ITV1+2+3 and Ch4. The picture on these channels is extremely bad, other times I cannot even receive the channels at all. I have tried retuning the TV various times over the past few weeks, but it is still the same. None of my equipment, including the aerial, has been changed or moved. Any ideas?? Is anyone else experiencing this? (I live in the Yorkshire area).
