Musical Xmas box repair needed (Roseville, CA)

I bought a Kurt Adler Xmas tabletop music and lites scenery box decor some years back.
One of my favorite collectibles.
However, for some reason mini ice skating figures should move and do not, also music part does not play.
Maybe a turn on/off switch is missing or some tiny wires came off, I do not know.
If anyone has experience fixing these items, contact me.
I can send a photo of the item later especially to send the bottom of the music box.
Obviously made in China, what is not made there these days.
But it was a very limited quantity just after the Adler Showroom store closed in San Franciso Bay Area.
Okay to see it in person first to see if it is fixable.
You will definitely need small tools and thin coated wiring if needed.
