My box has changed the date to 1st Jan 2000 - which means I can't watch anything. I tried re-tuning channels, which resulted in the box saying it couldn't see any channels (probably as the date is wrong) so i now have no channels. I also tried disconnecting the power but this made no difference. I have seen several other comments about this, but NO information from YouView on how to resolve the issue. YOUVIEW - PLEASE ADVISE WHAT TO DO?
