My Sony smart tv was recently set up and aerial linked into a talktalk box and I have been using that to watch and record tv and using the Sony handset to access YouTube. However I now wish to stop using the box and so plugged the aerial directly into the TV. I then went into system settings/channel set up only to find that the options for the analogue or digital settings were greyed out. I am not tech savvy so it's hopefully something simple that I've missed. Thanks for any help.
