Hi, Can someone please help me? Some of the channels e.g ITV2 and others have completely gone blank and everytime I go that channel a message saving 'please wait saving channel, frequency has changed' and once that has completed all the other channels have a message saying 'scrambled or bad channel'. I then have to take the plug out for the channels to work again but ITV2 and others still won't work and display the same messages as before. Please help me?
