Impossible Oberheim Matrix-6 Repair (Part 2)

This Matrix-6 was raided for parts, and whoever worked on it last really butchered it. Will I be able to bring it back to life?
Watch on and see me figure it out!

Great work - had one of these from a fire damage sale and it had issues different to yours but still took a while to get it there. Having a 2nd working unit to reference is invaluable. And yes the keyboard assembly/disassembly was a royal pita. But I now have two working so can stack or run them in true stereo for that huge Oberheim sound.

Nice work! I just recently reacquired my Oberheim Matrix-6 keyboard and installed all of my old patches on there. I'm running through a Boss Super Chorus CE 300 and a Bigsky reverb unit and my OB-6 is getting a bit jealous. Thanks for this great and informative upload!

Great job, congratulations man :) I just saw pin 5 of an IC is not inside the socket.It's on the very top just right below the display At 3:26 it's clear to see, there you point at it with the screwdriver.. but seems not to harm too much :D Thanks for showing the details!

I though you can't fix it, good job!
