Question about Yamaha Music
My Yamaha Clavinova CLP-411 has been perfect the 14 years I've owned it. In the past few weeks it has developed a cracking/static noise coming from the speaker. It sounds like the noise you hear when a microphone cracks real loud, although sometimes less loud. I don't want to invest a lot of money in repairs, but not sure what to do. I may consider buying a newer model.
Replace the speakers or let it be repaired by some one.their may be rust near the speaker coils.just giv it a try.

You probably need to replace the diaphragm. The diaphragm is located behind the back cap. Simply remove the back cap, remove the diaphragm, clean the voice coil gap with a piece of masking tape, install a new replacement diaphragm, reinstall the back cap. That it!
You can see videos on how to replace diaphragm at this link.

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.

call up Yamaha. They will fix it for free as it is a manufacturing fault.

check any and all filter,cross-over,and de-coupling capacitors in every circuit especially on the left channel side,but check all capacitors anyway on both channels,as one channel can affect both left and right channels, also a capacitor can heal itself over time and do the same thing again later,"Cold-Solder" joints can do this also, on a printed-circuit board, HINT:heat and cold can cause problems so,try heating, joints,caps,etc. or buy a can of freeze mist(to cool components) at an electronic parts store and gently heat or cool each suspect component waiting for the outcome,or wait till the condition starts and then try the cooling,because the component has already been thermally warmed up by the circuitry power
