Remove Cover on Korg Kross-88

Korg Kross-88 – Replace DC Power Input Jack

Is there an Official Korg Kross-88 Service Manual?

Which screws are to be remove to lift off the top/bottom cover? Is it just the outermost perimeter screws? Specific color? Any screws on Back Panel required?

I can always start on the outermost perimeter screws!

Suggestions welcome.

The manual is here;

However I would suggest asking at your local music store for a local tech who can repair the issue.
