I still could watch Prime and Al Jazeera English on 1st of May 2014. However two days later, after friend of mine told me there was an update for the Freeview TV, I re-tuned my Freeview HD box - VantageHD-6000T-NZ, then I couldn't watch Prime and AL Jazeera English any more. It always displays system message either "searching for signal" or "no video/audio signal". Since then I had tuned the freeview box many times, but unsuccessful. Even channel 100 - Freeview/HD has system message " searching for signal". Please help.
