Hi, My MZ-N707 will not record. It gives me an endless "TOC" message and makes sounds that I have never heard out of it or my MZ-N510 before. I have to pop the battery out to use it again and everything I recorded is lost. I have tried using the MIC IN and LINE IN jacks to no avail. Recording through USB is also unavailable. Is my recording head broken or is this something that can be fixed relatively cheap?
