I have an Orion TV32PL173DM which came with the house contents i bought just over 3 years ago, it is about 4 years old. I use to receive nearly 30 Freeview channels and it was working fine on sound and vision. I went over last week and went to watch French tv and many channels were missing so i retuned and all of the channels were HD bar Basse Normandy which worked on sound and vision. I did a factory reset and retuned again and all the HD channels were showing audio DOLBY D+, pictures and no sound. Any ideas please, or does it mean getting an HD separate Freeview box to make it work?
