Here’s what the piano looks like:
The retractable cover has three hinges each with three screws on each side to attach the outermost section of the keyboard cover to the main portion of the keyboard cover. (Click on the photo to see a larger version.)
The left and middle hinges are completely unattached from the outermost section of the keyboard cover, leaving the right hinge, which is only partially attached. In fact, the outermost section of the keyboard cover is close to falling off completely.
All the hinges on the sheet music holder foldout section and elsewhere on the keyboard cover are fine.
I have some, but not all of the screws that have fallen out.
