I have a TV purchased in 2017 which has the old one connect mini. The TV now fails to recognise that the one connect is plugged in and hence I cannot access any source signal. I purchased a new mini box and lead in the hope that it would resolve the issue. It didn't! It leads me to believe the problem must be within the TV itself. Samsung customer care can offer nothing save taking it in for repair to a local service centre for which I bear the cost. Anyone else had a similar problem? Am reluctant to give up on it as this was a £1250 TV when purchased.
