This happens to me now and again if live TV gets left on challenge after 
it goes off air. Only way I've found to fix it is to set up a recording 
on that tuner on a good channel. It usually doesnt have any problem 
changing channel to record something. Then just stop the recording.

The last set channel should then be a 'good' one, and live TV will work 
again
