My neighbour has just bought one of these but doesn't want to use the inbuilt decoder as he already has a Pioneer all in one dvd player / amp which he feels is better. He has been unable to get any sound out of it via the amp and asked me to look at it and I was shamefaced to have to admit that I couldn't fix it. The TV has a pair of audio outputs which go to the audio inputs on the amp exactly the same as on his previous old TV but I cannot get them to produce any sound. I have looked through the setup menus to see if there is anything I need to do to enable the audio outputs but can''t find anything. Have I not looked hard enough or is there a simple explanation that I have missed. I would be grateful for any advice received.
