Hi, I'm hoping that someone can help me. I bought a 70UM7450PLA TV and am having trouble with the TV Guide. I am using FreeSat here in the UK and get the following message whenever I try to change channels from within the on screen TV Guide: 'Preview is not available since programme information is currently being downloaded. Do you want to switch to the programme?' Also, in the banner at the top the the TV Guide it says 'Unable to Preview'. I have just had the Satellite LNB replaced and it is now showing Strength: 100%, Quality 94%. Any help or advice would be most appreciated. many thanks, Matt.
