Anyone had problems with the white box after getting a new TV? 

The box is working in that it shows the programs but not all the buttons work. A very important one for me is the mute button - it just has to get working! 

I tried resetting the box to see if it would get matched with the new TV but I couldn't get the mute button working. 

Just interested whether others had to re-match the box to a new TV.

I will try some more 'tricks', tomorrow.
