Medra Posted June 26, 2004 Report Share Posted June 26, 2004 Hi, I have a problem with my Sony MDS-302. The motor for the loading-chassis does not work. The motor itselv is ok, it works if I use an external Power unit (I took 5V). Could it be possible to solve the problem with a "global system reset" ? And how to do this ? Or could there be a problem with the motor driver IC ? Very thanx for your help, I hope I will get it run ;-) Greetz, medra PS: Sorry for bad english, I am german Quote Link to comment Share on other sites More sharing options...
Christopher Posted June 26, 2004 Report Share Posted June 26, 2004 Grüß dich! :happy: Not sure about this model, as it is a bit aged. We do feature the manuals for this unit here, along with other information: http://minidisc.org/part_Sony_MDS-302+S30.html Quote Link to comment Share on other sites More sharing options...
Medra Posted June 26, 2004 Author Report Share Posted June 26, 2004 Hi, hmmm, that page I found before, but no repair info about my problem or a service manuel ... Btw: My first MiniDisk Recorder was (and is :grin: ) a Sharp MD MT15. Any other info how to get the Loading-Motor run ? Greetz medra Quote Link to comment Share on other sites More sharing options...
Medra Posted June 26, 2004 Author Report Share Posted June 26, 2004 Otherwise ... does anybody know on which pin to get the signals for eject and for loading ? I think I could ask the "eject"-switch and the switch on the loading-unit for the loading-signal, but there are other things ... I think (I don´t know because I got it for 10€ broken from ebay) that it puts out the MiniDisk when it is turned off ... and perhaps generate other Signals for ejecting the MD. What I plan is that if I do not succeed in repairing the problem I will put an Atmel AVR 90s... microcontroller in the player to catch the signals and to generate the Signal for the loading/ejection - Motor ;-) Now it works with an external Power supply, but this manual handling is not so good. Later it shall work in my Stereo ;-) Greetings, medra btw: Does anybody have experiance in adjusting the Laser power ? When CD-Players will not work you can adjust the decreased laser power by a potentiometer... In the service-menue there is a Menuepoint named Laser Power Adjustment. Does anybody have experience with it ? I have probs with an older MD (which is played by my Sharp portable without probs). Quote Link to comment Share on other sites More sharing options...
