Scroll down to "get manual" and click on it to download a PDF file of the service manual.

Ignore other download links for viewers etc... If you have trouble, contact me at fredy2 at aol.com with YPG in the subject line.

It is a lot of work to open and access the key contacts. Here is your service manual:

I have two Yamaha's and I will say they are maintainable. Almost ALL the weighted piano key models use a keyboard made by one company as I understand it. I can easily get service manuals for the Yamaha, not quite as easy for the Roland... same goes for repair parts. Your decision... listen to each and decide. Hint: Use a set of headphones to do the compparision rather than internal speakers as the orientation in a music store can drastically change the sound.

Yamaha prefers to MAKE the instruments rather than conducting repair schools... they may have some very specialized schools for individual types when first introduced. With the situation in Japan right now such classes would be cancelled I am sure. Instrument repair is so specialized other than basic piano repair/tuning that you will find few if any courses. For piano repair you might want to search YouTube for videos. For organs and keyboards, detailed electronic knowledge and the service manuals are what we have to work with. You need both experience in digital and analog plus test equipment including oscilloscopes and signal generators as a start.

Here is your service manual... they should show you how as Yamaha's manuals are very good and complete.

You MAY find this is close enough... there is a lot of commonality of Yamaha pianos.
