I have a MZ-n510, I think you're right, I can't rec from any source, like line in or mic in, my recording head is really dead. Is it a solution? I live in south america and SonyMD support is N/A.
When I try to transfer from my Comp to MD, using CP4.0, after operation, my MD appears as BLANK. What's happening? I think that its start to happens after that I upgrade my WMP10 to WMP11. Thanks.
