My YouView box has stopped working. It powers on but then won’t go beyond the YouView loading screen, and moves between the waking up screen and YouView loading screen when it makes beeping noises when in the YouView loading screen. I have powered it down and waited for at least a minute. I have also tried to reset but that does not help. I think we've had the YouView box for 5 years after having an earlier white (??) one. Seems to have given up the ghost!
