Well last night my issue was the picture suddenly went a strange ghost colour, I rebooted as this has occurred before and the ability to record, and all my recordings were lost. I eventually had to factory reset to resolve the issue. This being a last resort whether you use a youview box, pc or phone.
this is tge second time this has occurred with the uhd yiunvuew box. 3 years with Sky and I still had the same box.
