Yamaha DX100 Project Machine

“Keyboard is in good physical condition. Some imperfections here and there. The universal power adapter I tried with it did not work, I do not know if it didn’t work because it is not the standard power adapter that comes with this keyboard. It does turn on with batteries. There is a section of 13 keys between the bass and treble side that do NOT work. All the other buttons prompt different reactions on the screen. The contrast dial work. The output quarter-inch Jack works, both of the bend dials toward the top left of the keyboard work. I tested out as much as I could. I am not guaranteeing I know every single thing wrong with this unit. May just be good for parts. May be easily fixed it could be a user error on my end. I cannot say for 100% certainty.” Click here to search for synths on eBay
