Yamaha Clavinova CLP-240 - No sound after new A/C power cord

by Dawn


I returned to my classroom after having a substitute for the day to find that my A/C cord had been destroyed to my Clavinova CLP-240. I went to the local keyboard store to purchase a new cord, and he gave me the one that he thought I needed. It fits, and the keyboard turns on, but there is no sound. I don't know if this is related to the new A/C cord or not. Can anyone please tell me the type of A/C cord I should have so I can make sure that I have the correct one?

I would also love any additional information regarding why the unit will not make any sound.(I have already checked the master volume, there are no headphones plugged in, the speaker switch has been turned to normal, and the Local Control is ON).

Yamaha CLP 240 Power Cord-No Sound
by: Alfred

Dear Dawn: I am not familiar with the CLP 240, other than to know it is an 'upright type of electronic piano". From what you've checked (Unit turns ON,Headphone connection, Speaker Switch, Local Control)I seriously doubt the new cord has anything to do with your problem. I believe that whatever caused the destruction of the original AC cord may have been linked to a violent jerk (foot caught or similar) and that an internal circuit component has been dislocated.
My recommendation is that you return to the local keyboard store and ask them to refer you to a QUALIFIED TECHNICIAN who can effect a repair. Good luck.
