Yamaha clavinova won't play C natural in any octave

My yamaha clavinova CLP-260 will not play the note C natural in any octave. I haven't spilled anything on the keyboard. I haven't used the piano in several months; last time it was working fine. The piano demo piece plays properly. Any advice would be appreciated.

    is there a way to reset the keyboard back to original factory settings? E-Key will not play on all octaves.

Hi ...
There are flexible cables that connect the keys to the main electronics. The connectors for those cables sometimes age poorly..
It is fixable. But dont "get taken" on a repair.
If it's just resoldering a few points,it shouldnt be more than $100.00
to fix

I can't connect a usb device with music on to the clavinova.

You have to format the USB stick using the Yamaha Clavinova. The reason is that the keyboards expects certain file/folder structures on the stick. If you format it on the computer, the computer will not know what files or directories to create for the Clavinova when it formats the stick.

Successful repair of my Yamaha Clavinova CLP 880

The principal to replace your contact strip will require one further step to that shown here where the customer has replaced the felts.

When you have the keybed out you will see the contact strip part 220. This is held in place behind the circuit boards. Remove boards, replace strip and reassemble.

It might be worth considering felts whilst you have the keyboard in bits as these wear out.

G# and A# Ghost Notes!

First try looking in your transpose settings. Refer to your manual to see if any arpeggiation/unnatural chord settings were inadvertently created by you or made by another user. If you believe it is a software problem you can not solve, back up your memory bank, remove your memory card, and hard reset your keyboard. Insert your memory card and check to see if your problem still exists.
If it is a technical problem, it sounds like you may need to get it checked out by an engineer/repairman. Sometimes when a digital keboard's keys collect too much dust/debris they can trigger multiple keys that aren't being pressed. Think about it like a key getting caught on an upright piano and pulling back the hammer next to the one that was played. A digital piano works off of one or several printed circuit boards or PCBs. The printed circuits usually can not short circuit because the wires and circuits sit in fixed positions. If an alien conductive fiber or series of conductive fibers connects a conducter to another, or if there is any humidity inside your piano it may cause circuits to misfire when a circuit is connected in the area. This could explain why notes you are not playing are being activated in the area in which you are playing.

If you are in a humid area and you suspect that this may be the cause you can attempt to draw out the humidity before getting a an expensive diagnostic done. Find a box large enough to house your keyboard. [If it is on a stand take it off and] place it inside the box. Cover the keyboard with plastic wrap (so as to prevent any foreign objects from getting into the instrument) and very carefully surround the piano with white rice. Remove the plastic wrap, close the box and leave it alone for a few days. The rice draws out any moisture from the electronic components. Very carefully (again so as to avoid getting any rice inside it) remove the keyboard from the box; remove any dust from the body, face, keys, and other components. Try your keyboard now. If humidity/moisture on the PCBs was the problem it should be solved. If not it is time to take your piano for a tune-up.
Hope this helps!

I'm using the Yamaha P-85 Digital piano. Unfortunately it has lately had some problems. When I'm playing to notes next to each other (especially e and f (mi & fa) or b flat and b (si & si...

In playing fast you have to make sure to release the note fully and let the key come up. These keys have TWO contacts that are used in the scheme to measure note velocity. If BOTH contacts don't open, the note will NOT re-fire. The second symptom you have written would be a characteristic if one of the disconnect diodes has shorted. These diodes direct the strobe signals that scan the matrix of key contacts to avoid other octaves responding when multiple keys are depressed including those in other octaves. Servicing of the unit is required. It is unlikely you have the tools to DIY this problem. ONE THING to try is to tip the unit and gently tap it to see if some debris MIGHT have fallen in that may be shorting some of the matrix connections.

Our Yamaha clavinova CLP-115 is buzzing, even with

Without power to the unit no sound should be generated. Make sure there are no other connections.

MAYBE you have a wall transformer behind it that is buzzing. MANY wall transformers develop buzz.

Another source is flourescent lights and even some of the low voltage halogens have noisy transformers in the base.

Yamaha Clavinova CLP 260

Your L/R jacks in the back need to connect to the "line-in" connector on your sound card.
I think the jacks on the Clav are 1/4 inch. Go to Radio shack and ask for an adapter that will take two 1/4 inch plugs/cable and convert it to a 1/8 inch stereo plug.
The Midi connects From (keyboard) To (soundcard)
Cables are available at any music store

Yamaha digital piano clp 170

This is a common problem with Yamaha keyboards. The problem is caused by worn-out rubber contacts in the keyboard assembly. In my old Clavinova CLP-500, there was one long rubber contact strip under the keys with two parallel strips of semiconductor material. The Clavinova circuitry determines key velocity by measuring the timing between when the key hits the first and second strips of semiconductor material. The harder you play a key, the less time it takes the key to hit the second semiconductor strip after hitting the first.
After years of playing the keyboard, the keys eventually cause tears in the semiconductor material and this messes up the timing measurement for key velocity. The only solution is to take the keyboard apart and replace the rubber contact strip with a new one.
I got rid of my CLP-500 four or five years ago and got a new CLP-170. The CLP-170 is now having exactly the same problem that the CLP-500 had. Yamaha has re-designed the rubber contacts in the CLP-170 so that there are now eight individual contact strips instead of one long one. The problem is essentially the same, though. You have to take the keyboard apart and replace the worn out rubber contacts.
Here are the part numbers for the rubber contacts that need to be replaced in the CLP-170: V8286600 Rubber Contact, 12 keys, D-C#   Qty. 6 V8286800 Rubber Contact, 11 keys, A-C#   Qty. 1 V8286700 Rubber Contact, 5 keys, D-C   Qty. 1
I suggest you also get a copy of the CLP-170 service manual, part number 001677. It has descriptions of all the steps necessary to take the thing apart and put it back together again. You'll also need a "rod" (which is just a long dowel), part number TX000670. Before you take the circuit boards off the keyboard assembly, you have to insert the dowel between the keys and the frame to keep the keys from falling back and getting in your way. A 5-foot long 1/4-inch dowel will probably work. (I haven't yet taken apart my CLP-170, and I don't have Yamaha's "rod," so I'm not sure if 1/4 inch is the right size or not. I'll report back here if it's not.)
Good luck, Howard
