I bought a KD-49XE9005 tv in July 2017. Initially, everything worked fine and I could, when needed, connect to BBC iPlayer and ITV, Channel 4 and Channel 5 internet/catch up services.

However, a week ago this no longer became possible. The apps are there but when I click on one of them after about ten seconds a message comes up saying "An error has occurred. Please try again later". When I click on the OK button I get thrown out of the app back to the home page

The fault can't be with my wi-fi because I can still stream Netflix and Amazon.

Does anyone have any idea of what is wrong and and how I can resolve it. Thanks.
