Turn off the p155 power.
Press & hold down the rightmost key (C7) while turning on the power. Once the power is On release the C7 key. It should reinitialize to the original factory setting

Sustain Pedal works intermittently.

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.

Sounding a half step too high

Use the factory reset
Hold down highest white key whilst turning on
This should return to factory settings - pitch should now be back at A440
If you need to adjust then see page 19 of the user manual where it explains fine tuning.

How do i reset the keyboard to factory settings? It sounds really weird right now

You can normally reset Yamaha keyboards by holding down the highest note while turning on. If you want to do a full factory reset see below - remember this may delete all songs etc you have saved to the keyboard memory.

Read about initialization on page 61 of your user manual. This is a factory reset. There are two procedures there. If you don't have the manual download it here:

Yamaha P155 wont power up, replaced power supply w correct one. Any ideas?

Double check the supply... it should be a PA301 which is 16 volt DC at 3.5 amps... fairly hefty one.

Download these schematics:


A lot of Yamaha have similar circuits between different models.

When you go to these links, scroll down the page looking for a small link "Get Manual". They will only let you download two a day without registering.

The first of these has the power entry on page 154... the second is on page 60. Both use the 16 volt power adapter. See if one of these schematics is not close enough to your unit to troubleshoot it.
