I have a KDL50W829 and usually my apps work okay, but this weekend, most of the apps seem to be missing, except for my favourites, but nothing will connect, when I am prompted to refresh internet content, I get error 5010 unable to connect. Not even youtube works. All these work on my tablet, no problem, but my Sony TV just will not operate the apps.

I've reset routers, powered down completely etc, but nothing works. Its driving me mad.  anyone got any suggestions or information? I'm assuming the problem is at Sony's end.
