Hi, I wonder if anybody could help with a problem I've got on a mission SUB, I've had it just under a year and recently left it off for a couple of weeks. When switching on for the first time again the sound was very muted. I switched off and later on again and everything was fine. One day later, I switch on again, get the muted sound again, switch off and it wont go on again. Not hot, hasent even been on again and now the SUB is totally dead. Tried power supply's all ok, just no power in the SUB, all LED's off.
