I have a Sony Bravia Smart TV, KDL-40W605B model. Today all the APPS have disappeared. I have checked internet, it;s fine. But I have rebooted the HUB, still no APPS. I have checked the internet connection on TV, all OK. I have restored to fctory settings. Still no APPS, In fact, I have now lost the BBC I Player APP that I actually DID have before the restore. How can I get the APPS Back. I have only had Amazon Prime for three weeks and now I can't watch it!
