I have a yamaha Dgx 500 that I am attempting to repair.
There is no sound from the keyboard, the control buttons are not working, the display is light up, and the disk in use light is on.
I am guessing that there is something wrong with the floppy disk drive and that is the source of the problems.
I am wondering if anyone has any advice or schematics for this model. Thanks

Thank you so much I am grateful for you taking the time to share the service manual. I would appreciate any advice from anyone that has had a chance to repair this or another similar yamaha piano that has a floppy disk drive. I will update on my progress.
