KX88 repair


 

Hi everyone,

I recently acquired a yamaha hx88 however it's a bit scuffed up. Everything seems to work except the battery (easy fix) and the top row buttons (A1~A16)
My tester says the buttons and flat cables work. I see no visual problems. What could it be? A bad contact? Should I spray some deoxit?
Does someone have any schematics? There service manual doesn't include them.

Thanks,

Roger

Hello,
Just bought an used DX7 and my question is about how to hook it up in logic pro x to record. Can you use a Midi to usb cable? Or do i just use the midi conections and the audio out in to my interface?

My advice in FB group about bent key contact didn’t help?

I have schematics.
