All aerial you view channels disappeared
The picture on all channels were poor and distorted after a power cut so I did the usual retune and the result was NO aerial channels available only 70 pay for ones! I have retuned 3 times, I switched everything off and started again, I phoned my broadband supplier in case it was anything to do with them. They say nothing g to do with them. When I switched on the Tv and You View after the power cut there was an update so I agreed to the update. Help?!
