Speaker trouble for the Yamaha Clavinova CLP-560

by Kristi
(Iowa)

My keyboard speakers lock up after too many keys are played at once or when the volume is to half its maximum capacity. It doesn't make any sound after that and still doesn't after turning the keyboard off and on again. What would be the cause of this? Are my speakers shorting out or perhaps a loose wire? Any help would be much appreciated.

CLP 560 Speaker Problem
by: Alfred

Dear Kristi: The one point that Both Dick and I have touched on is the Headphone. Among the points you are checking, examine the HEADPHONE JACK leads and contacts. This item can be intermittently cutting out the Main Speakers.

Thanks

Thanks for all the input. I need to do some more evaluations before I do anything specific. The speakers still work, but they come on randomly-not sure what the trick is yet. I will take your suggestions and try out the headphone jack. I will post more as I get a chance to try things out. Thanks again.

Hi Kristi,

Did you try a factory reset?
Your manual will tell you how to do that.

Make sure there is nothing in the headphone connection.... like a headphone, because that will disconnect your speakers!

Another try..
If you connect a headphone to your keyboard or when you connect it to an external amplifier (stereo-unit or something with speakers)do you hear normal sound from your keyboard?
NOTE: first power up keybard than the amplifier or you can hear a LOUD BLOB from the speakers!
If you hear sound (or that loud blob!), you are kind of lucky, it is most likely what Alfred already mentioned, the keyboard-speakers have packed up.
If you don't hear sound at all it can be a lot more, like the internal amplifiers and/or one of the boards. I'm afraid that can be a costly repair.
Anyway in both cases you have to go to a qualified Yamaha-repair-person.

Hope this helps you to solve your problem, let us know what it was please.

Speaker Lock-up CLP 560
by: Alfred

Dear Kristi:As a follow-up to my earlier comments, if your unit has a Headphone feature, connect a head set and at LOW TO MEDIUM VOLUME, listen for sound. If the keyboard works in that mode, your main speakers may be shot. In any event, do not attempt any DIY solutions. Have a qualified professional do the job. Good luck.

Speaker lock-up Clavinova CLP 560
by: Alfred

Dear Kristi:

The Speaker Cone is centered within a minimal space between its Coil and a magnet, and fluctuates back and forth reproducing sound. If by a freak coincidence both speakers of your unit have been knocked off-center, they can “lock up” as you’ve described. This is possible when too many keys are simultaneously played sending an overloaded signal for sound reproduction (this usually first results in distortion). The lock-up could in turn cause the very fine-wired Coils to heat up and fail, so that no further sound is produced after you start up your keyboard again. If my explanation applies, you should have the unit checked by a Yamaha-authorized or qualified professional. The Speakers will probably have to be replaced, and more importantly, some component in the circuit can be defective, allowing an over-amplification of sound. Hope this helps. Good luck.
