I have a Bravia KDL 40BX400. I can get no sound from any of the units connected to the TV, the PS3, the Wii, or the DVD. The cable box works find but none of the others produce any sound. This is a fault that has just occurred recently. Up to a week ago it worked fine. I've tried restoring factory settings in case one of the kids has latered something but no joy. Any ideas please?
