turn off power press and hold in ch up key till it stops showing pace let it boot look,s almost as if it,s off but leave it alone and see if you have the fta ch,s
you useing a mosc of fun ? if the pay ch,s show up a blank screen the key,s just need to update
also if you did do a mosc did you put the ird in bbackward,s instead of 12 ** ** ** it would be ** ** ** 12
if the bk ird is good then just flick through the free ch,s speed it,s up sometimes longest i had to wait was 45 min,s so go make a cup of tea have a puff what ever and have a look again in a few min,s
