Where can I obtain or download a service manual for the repair of a Yamaha DC2 ll disklavier grand piano.

SOURCE: Manuals for Concert Piano Korg C-15

I have a Korg Concert Piano (C-15S) which was working perfectly till about two months ago. I have been on vacation for two months, had left the piano unplugged from the electric supply point, but on re-connecting now, I get no sound from it. Is there a reset button (or other device) that I may have to use? Appreciate your advice.

Thank you,

L. Paul

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

SOURCE: Recently I discovered a long fine crack in the soundboard of my 5'7" grand piano. Is there a way to repair the crack?

If it truly a crack any repair needs to be done professionally. The board may be joined or glued from two pieces and the glue line MAY show. If the crack is very straight this may be the case. How is the sound? If it is normal then just watch it for any degradation.

SOURCE: Where can I get a manual for portable grand D6X640 Yamaha piano

Do you mean the DGX-640? To my knowledge, Yamaha doesn't have a D6X line of keyboards. Most of Yamaha's manuals are available from their support page: http://download.yamaha.com/top/?site=usa.yamaha.com&language=en . The DGX-640 support page is http://download.yamaha.com/search/product/?language=en&site=usa.yamaha.com&category_id=16084&product_id=1056822 . Scroll down to find the owner's manual in various languages and other documents. Yamaha provides javascript links to the manuals on the site; these do not resolve to specific direct links in my browser history.

I hope this helps.
