My MDS-JB940 records and plays back OK, but when I eject the disc and re-insert it, I discover it has been completely erased. Also, if I insert any previously recorded discs and make any kind of 'edit' on them, even a single new track mark, it does the same thing-erases the whole disc when it is ejected from the deck! BIG BUMMER! Sony Service in Irvine wants $146 to do anything on the deck-I'm questioning if it's even worth this to get my deck repaired. Does anyone out there have a clue about what might be malfunctioning on my deck, and how I might repair it myself? (I'm an 'Engineering' guy myself.) Does anyone out there know of any competent independent minidisc repair people?
