Author semi broken juno 106

so i finally powered up my juno 106 after about 10 years of no use (stupid, i know), and some of the keys do not work. all the voices are working though, sounds great, and with a midi keyboard works fine. i dont know anything about this stuff.. is it an easy fix? should i poke under the hood a little bit?

It sounds like it just needs the key contacts cleaned, it's a PITA, but not rocket science.

Yeah. Just pull the rubber strip off and swab the contacts with some naptha. Some people say isopropyl alcohol instead. It's pretty easy.

been playing with it, and i realized the problem probably isnt the keys themselves, nor the contacts. certain clusters of keys dont work, for example, c, c#, d, but every other octave. also the F# key, every other octave. its perfectly symmetrical.

Yeah, this is characteristic of the keyboard scanner when there are bad connections between the keyboard and the CPU board. Try opening it up and re-seating the ribbon cables.
