I have a Samsung UE40EH5300 smart TV and since I bought it, the digital interactive stuff on the red button on any BBC channel does not work. It puts up a message saying "Due to a technical fault, this service is currently unavailable, please try again later". The service works on my other Samsung TV in the kitchen so does anyone have any idea why it's not working on this new TV? The interactive stuff on other channels works, just not the BBC stuff. I've retuned, changed country settings and back to UK and can't figure out why it simply won't work. Anyone?
