Once inside you can see the power supply board on the bottom right of the piano. You can identify it it by the large power transformer on the right, and a large black capacitor on the left.
There are two cylindrical glass fuses side by side in clips on top of the board.
With the piano unplugged from the wall, you can pop out the fuse from its clip and replace.

Date: Mon, 19 Jan 2015 17:13:14 -0500I”m happy to report the piano is playing happily again with the simple replacement of a fuse in the power supply.
I’m guessing there was an excess of pedaling in one of the midi files I was playing back.Thanks Bill!JeffOn Jan 19, 2015, at 2:16 PM, Bill Brandom bill.brandom03@...

I would guess the pedal solenoids draw a fair amount of current?Jeff;Easy enough to replace.JeffOn Jan 19, 2015, at 2:11 PM, Bill Brandom bill.brandom03@...

In the older Disklavier pianos, if they were pushed really hard (lots of keys at once with high velocities) it was fairly common for the 7 amp fuse to blow.BillOn Mon, Jan 19, 2015 at 10:46 AM, Jeff Joseph josephaud@...

My MX100 has been cheerfully playing away from its floppy discs and midi connection until the other day. It not will not play from either source. (I thought it was a MIDI issue until I popped in a floppy)
Any thing to troubleshoot?
IS there a silent mode switch?
