When I was looking for PS-560 service manual, I found this instead.
For anyone in need, please use with caution.
Enjoy !!

A few hours after found the MZ-X500 SM, I also stumble upon this.
I know some of us think this could be dangerous for people who don't know what they are doing (and I agree) , but even I, who have 3 years of electronics engineering education, am not too brave to take apart my own keyboard - maybe I'm just too stingy.
 
But for people who have a brave and adventurous spirit - I was once upon a time, this file can be very helpful.
 
Once again, be careful!! The risk is in your own hands.

on Where can I get a Service Manual? How to activate the diagnostic Mode for MZ-X series? I think there are no full service manuals uploaded, I've stumble upon this file after searching on the web, hopefully it can help people who in need.
