Hi @Naz7866 Firstly unplug disconnect tv and connections from the mains for about a minute before reconnecting to see if that solves the issue. If not whilst there does not appear to be an issue with cabling I would suggest you disconnect the cable from the One Connect Box before reinserting to see if that makes a difference and if the screen menu is displayed. if still problems there may be an issue with the One Connect Box but would to connect Samsung Support for advice.
some further information in this article https://www.samsung.com/uk/support/tv-audio-video/my-tv-wont-turn-on/
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
