Glad to have you drop by again. I noticed that you've asked this question before, so I'm sorry you didn't get a better answer at that time.
But just so you know, this forum is meant to mainly support US products and customers, and unless I'm mistaken, that TV is a UK model. 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/support/model/UE40C6000RKXXU
But we got a helpful little community here, and they might have a few other suggestions to help you out.
Hope this helps you!
