gIzzE: i've just tried swapping the audio board with the one that you sent me. I've still got the problem. The other boards (power board, main board) are a trickier to change.
makkan00: The audio board is ok. So a reset might be whats needed. Have you ever fixed a problems similar to mine by perform the reset you described.
Both: Thanks for your help so far.
Its really interesting trying to fix this especially as i'm swapping boards inside the head unit.
1. Audio board
