I don't know if anyone can help me. I have just brought a second hand NWZ-S515 walkman player and sometimes it will not turn on, other times it will turn on just fine. And occasionally when switching on it will say repairing database or repairing mp3 files or something, can't remember really. I is just really intermittent if it will turn on or not? It is running firmware 1.0, is this the latest firmware for this player, thanks again.
