Korg C-15

The Korg Concert C-15 is a digital piano and midi keyboard from around 1992. It has 88 full size keys, two pedals, built in stereo speakers, and a plastic music stand. The C-15 is closely related to the C-25, and shares many elements with the C-35, C-45, and C-55; much of the repair procedure applies to all 5 models, but this article was written with a C-15 for physical reference.

Disassembly Notes
The upper housing is attached with a hinge to the rear, and four screws along each side (see diagram): the front-most and back-most outer screws at the front legs' supporting panels, and two more screws at the middle and back of each side. Grip the front corners on both sides, lift and allow the housing to rotate up like a car hood.
