I recently bought an 50LB650V-ZN and as they have been out for a while i assumed it woukd need updating straight away. ive connected it to the internet and when i click check for update i get the message 'Unable to check for updates' i also bought a magic remote and after about 5 minutes of using it a pop up will appear saying 'failed to update magic remote' then the magic remote will turn off and stop working until i remove the batteries and put them back in again. ive asked at the shop where i bought it and they say the TV should need updating straight away as its been available for about 8 months and that the magic remote doesnt actually update, only the software on the tv will update to support the magic remote. ive tried to download the software update from the lg website but cant get the files to unzip so my tv doesnt recognise the files. anyone come accross this problem before or know how to fix it? any help would be appreciated thanks
