Prophet 5 intermittent keys

Hey all,

I also have a Prophet 5 rev 3 and some of the keys are intermittent. I’ve tried continuously activating the key to clean the contact/j wire but it doesn’t seem to always work. I’ve been using it remotely via the keys of another board.

any ideas on what I can do myself if I open it up?

thanks!
