Well, mine have been repaired in japan by the store I buy it from (Brando) ... as it was still under warranty I just had to send it back to brando who then managed to get it repaired and sent it back to me for free ... now it's fried (again) as my girlfriend have done the same error as me , reverting the DC polarity and I'm hoping too to find another way to repair it as it's not under warranty anymore :/
