Hi Mr_C-B

Thanks for your message. I appreciate the detail you've put into it and the steps you've tried already. But just so you know: if you want Samsung support, I support US products and customers. And from what I can tell, this model is for UK. (Correct me if I'm wrong.) So while I can't help you directly, if you want Samsung help, here's the Samsung UK portal for support on that product: http://www.samsung.com/uk/consumer/tv-audio-video/television/led-tv/UE40ES6300UXXU

Hope this helps you!
