Disklavier

this is a common problem. Try going into 'Pedal Calibration'.

You need to go into the basic menu (little red-ish icon at the bottom left on the grey bar of your PRC-100 screen). Then select 'Service Centre'. It will come up with 3 options, one of which is 'Pedal Calibration'. After that, follow the instructions on the screen.

If this doesn't work, you would need to get a Disklavier technician in to check it out.

The only way to get the pedal working again is to send the DKV to standby and then start it again. The file will then play again with normal pedal action until it gets to the point at which it stops.
