Most of the Apps (BBC iplayer, itv hub etc.) are not working on my Sony Bravia KD-55XE7073. I can go into the apps but as soon as I select a program to watch the screen either goes black or I get a continuous turning circle in the centre of the screen. I've checked the speed of my router and I'm getting 60 mbps and I don't have any issues using the apps on my laptop. The only app that does seem to work is Netflix.
