greetings to all, i have a sony mz-n710 which is having problems, it all started when i took it off charge and kept on trying out different discs to see wots on it, i thought they were empty, then i went back to the first disc which was inserted and no sogns were playing from it, it refuses to play ne music, it makes a weird noise, like a bubbly one and keeps buzzing, i tried cleaning it, trying new discs, charging it agen, nuthin dun it, i looked inside it and next to the laser on the left hand side (looking down at the disc) there is a black stick sticking out about 5-20degrees, is it sposed to be like that? cn u suggest a solution? or maybe send me a pic of a helalthy inside/mechanism of a sony mz-n710 thanx r.soul
