Hi, I've owned M6si for over 5 years. I've had crackling sounds and took my unit back to my dealer to get it diagnosed. Problems with both power unit and capacitors. Quoted me about 33% of the cost of a brand new unit to get the problem fixed/replaced. Pissed like mad. These problems shouldn't be having for relatively new units like mine, it's kept in a well ventilated place and not used daily. I don't drive it hard too. Service guy tells me it's a common problem with this model.
