What you're beng told is to reset the instrument. T/his is als refered to as reboot, or reinitalize. The instructions are at this link-

Resetting Yamaha NP31 Portable Keyboard

To start with always best to use the correct power supply these should be readily available from any good Yamaha store. Is the sustain pedal a Yamaha pedal? The plug end of the pedal connect a multimeter across the two connectors and set meter to show continuity. If there is no continuity press pedal, hopefully this will now respond. If not then the break is in the pedal. If meter idea works then it could be the socket on the keyboard, these can work loose on the pcb they are mounted to if they are used a lot.

You could open up the keyboard and look inside checking the solder joints on the socket or simply take to a Yamaha service centre.

You could also try a master reset of the keyboard, hold down the highest note whilst turning on, this will reset to factory default.

Let me know how you get on.

There is a contrast control knob on the rear panel of the keyboard..

HI, Let me answer the question.

1) Select the DUAL VOICE (not portable grand ) button and hold for longer than 1 second.

The choose voices required.

If you press the Portable Grand button this resets the keyboard top a piano.

I hope this helps
