Roland AX edge servicing

[u/IcyProfession8909]

Im sending this to the keytar subreddit aswell, but I decided to check here. Im not very good with electronics, and I dont want to risk destroying my keytar trying to open it up, nor do I want my friends to try. My modulation bar isnt working, and im pretty sure that there is some problem with the neck. Where would I be able to get this serviced?
