I bought my first MD, an MZ-N1, from E-bay and, on arrival, it basically doesn't work. When I attempt to play a disc, I get a read error. When I attempt to record, I get a record error. When I try to connect to my PC, it is often not recognised as being connected and when eventually it is recognised, I get a 'no media' error. Is this player a dud or does anyone think it's possible to fix it? The seller, of previous good repute, has now unregistered from E-bay and is not co-operating. If it's dead, is there a market for accessories like the charging cradle, remote, optical lead etc. so that I can try to get some money back? All advice gratefully received.
