gary Greenspoon Posted December 17, 2013 Report Share Posted December 17, 2013 I have two MZ B10 units. One I've used for a long time, and one bought new as spare some years ago and never used. When older unit had trouble reading a disk, I tried it in "New" unit and had same problem. I have a third working unit, and confirmed all discs tried were OK. A local authorized Sony repair shop said both optical sensor were bad, and no parts available. As one is brand new, I'm doubting technicians assessment. Question: 1) Can the optical reader be adjusted/ calibrated? 2) Where is a good place for repair in North America or UK?I'm replying to myself just to see where any replies will go to.I'm replying to myself just to see where any replies will go to.

hobby30plus Posted December 17, 2013 Report Share Posted December 17, 2013 Try to buy used MD walkman with working LCX-5R optical pick-up and then do the swap following service manual from minidisc.org. I did this with my MZ-B50 when I removed broken LCX-2R OP and installed working LCX-5R from MZ-N505 which had problems with disc spinning motor. My MD voice recorder works perfectly now. 1) Yes, it can be calibrated in service mode, but don't do that if you haven't done it before! You also need laser power meter which is not cheap equipment.
