Late last week my KD 65AG9 had a software update, after this some of the functions ceased to work properly, I powered down the TV and left for a minute and then restarted it. This cleared most of the problems except for the access to TV text via the BBC channels. This does not function and I have checked using another TV and all is fine with the service. The text button and the 4 colour buttons associated with the text button on the remote control do not work. Is there a software issue with the latest update or is there a fault on my TV since the update on Friday? The TV is 11 months old and this is very concerning for such a quality TV to have such an issue. Can anyone help me?
