Running a Pioneer 435xde with Sky which runs no problems. When I pick the freeview digital channels - channels 1 and 2 are perfect - three and above are garbage as if the reciever has lost sync, distorted and large scale pixelations all over the place. Plug in a normal TV and the pictures fine... Before I climb on the roof and reterminate all the cables, any ideas why it does this ? Is there a service menu which will show me the digital strength ? Thanks in advance..
