By any chane a liquid has spilled over your keyboard? it's kinda hard to dismantle that keyboard. but it can be done. i wonder only how it could get sticky as you described. i am from yamaha service before and i have seen the mechanicsm of clavinova, it should not go like that except if you had spilled something on it.

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.

The keys on my CPL130 piano are intermittently failing to sound the c's and f sharps. All the other notes appear to be OK. what could be the problem and what might be the remedy. Have had the piano for...


well..that is caused by one of three things

a. the sound board(really a digital one) could have some glitches on those keys.

b. the tone recognition firmware, which looks for particular 'keys' may need to be revised and updated

c. is it the case that all 'C' and F# are bad, then it's most likely digital and not mechanical..

please confirm actual failure mode..

Clavinova is stuck on piano only it won't change on any other button ...any ideas?


That button is probably stuck, dirty, keeping other buttons from changing it. It is a delicate operation but, if you can somehow open the unit and clean the switch under the button with some contact cleaner and free it up it will probably work. switches and buttons get dirty and corrode over time. Let me know you're outcome and we can troubleshoot further.

Yamaha Clavinova CLP-440


It sounds like you have a part overheating and failing, then cooling off and starting again. i would take it into the nearest Yamaha repair facility or contact your local authorized repair to come take a look before it goes out of warranty.

I know that a Clavinova cannot get out of tune, but - in the lowest two octaves - my mom's CLP-115 sounds as if it is. Might this be a problem with memory, speakers or circuitry? Any idea how we might fix...


Realize that it MAY be stretch tuned like a real piano. A real piano is tuned increasingly sharp above middle C and increasingly flat below middle C. At the ends, the the off tuning is about 20 to 22 cents sharp and flat. The Clavinova should emulate this. In a real piano this makes it sound better and prevents some cross coupling of harmonics. Read up about stretch tuning on the internet. The Clavinova gets its reference from a quartz crytal oscillator and they just dont' get out of tune.

Yamaha clavinova clp 200 - ear phone jack slid


The control panel hinges upwards and you have to move the keybed back a bit to get at the jack. All the screws on the bottom for the keybed. I'm not sure where the ones for the control panel are.

Fredy 2 I am trying to play chords with my fingers, there is no sound, if it is on any other mode the chords work but i need it to be on fingered mode thanks doreen


OK... It wasn't clear from the original.

Sometimes the keyboard has a mode that splits for upper and lower part of the keyboard, usually splitting at the F#/G. Also CERTAIN voices will ONLY sound one note at a time. Piano setting would not have this problem of course.

When you play a single note does that sound? If it doesn't in the fingered mode, then there may be a processor problem in the unit/

If it does, there is probably a problem in the matrix that scans the keyboard electrically. If one of the keys were ELECTRICALLY stuck on, the processor within could not read whole sections of the keyboard.

To troubleshoot the problem, press exactly one key at a time... do they all work for say a piano voice while in the fingered mode.

Next press a key at the high end of the keyboard and try others. See if you can find an octave that fails to work.

The problem is likely imbedded in the electronics and could be anything from a dirty key contact to a cracked circuit board. It is NOT likely you can fix this yourself unless you are experienced in electronics.

Yamaha clavinova won't play C natural in any octave


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
