Hello, I have bought a mint MZ-E2 in my country that doesn’t sounds. It chargues, it displays the name of the songs and discs but it sounds metalic noises trough the headphones. I think the disc rotates well because it displays the names of tags. If I pass the songs I hear the laser movement but it don’t sound anithing, only a metalic noise 1 second. Any idea? I have entered in service mode but I don’t know if changing any parameter will repair the unit? Thanks!!
