ustravis Posted June 20, 2011 Report Share Posted June 20, 2011 Hi everyone, Have one question about the internal mic. I got a Sony MZ-B100 that got its internal mic disabled. Wonder anyone know how to enable it? Thanks. Quote Link to comment Share on other sites More sharing options...
sfbp Posted June 20, 2011 Report Share Posted June 20, 2011 Hi. Are both channels both cut out or only one? Either way: a. somehow the insertion into the (external) microphone socket caused the prongs to stay in the "inserted" position; or b. one or more of the ic (IC305,307, Q313,Q515) in the circuit that switches between internal and external blew. This only from casual inspection of the service manual (at page 31) which you can find here. I don't claim to understand that circuit, though. Maybe you do. If not, of all the people who read this board, Jim Hoggarth repairs these MD units professionally, and can probably help you in due course. Welcome to the forums.
