Disklavier

Sounds like you blew a fuse.  There are 3 of them on the main board inside the bottom of the piano.  These are replaceable from Radio Shack.  Just get the correct size.

I think I put the service manuals on www.midiplayertools.com to see the schematics, but they are pretty obvious.

Yes, you will always need a working floppy disk in the control box for the piano to work.

It is a true "Disk" instrument, in that it actually plays from floppies (getting a little hard to source!) I had noticed a more and more frequent incidence of problems with the floppy drive, in that it would suddenly skip to the end of a tune or something like that. I had almost stopped using the floppy altogether, and just used a laptop plugged in with a MIDI interface to drive the instrument, though I had to put a floppy into the drive to get the instrument to pay attention to the MIDI interface. (Is that normal?)

Since then, it won't power up. When the instrument is plugged in, and I turn on the power switch (below the treble end of the keyboard), I hear a faint click, but nothing on the floppy unit screen, and nothing happens when I turn the floppy unit on or off.
