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