hiya guys,,,the audio in the headphones stopped working,,,and the machine still worked,,,changed batteries,,now nothing works,,,,speaker or headphones,,,and because i cant hear a thing ,,,the machine could be totalled,,,,has had only 30 hrs use max,,,but two years old,,,and i dont have a 3 yr warranty like they brought in 2010,,,,,,has anyone any idea if its a connector problem,,as after only 25-30 hours use these machines shouldnt be going wrong,,,and if so minelab should stand by their products a little closer,,the minimum charge for looking at it is
