How do i replace one key on Yamaha YDP161?


A YDP uses the same key type as a basic Yamaha Clavinova. As you have stripped the keyboard to reveal the keys take a look at the end where the key hinges. There will be an arrow pointing to one side. You will need to remove att the screws holding the key base (black plastic ) to the wooden base. Slide the whole keyboard back a couple of inches, push down where the arrow points between the keys, the offending key will pop up. Slide forward and jiggle out. Replace key. reassemble. If the tag on the back of the old key has snapped off remove the piece of debris that might be there before refitting.

I Need a power board for a Yamaha YDP-121 digital piano


Is the board missing? If not, just repair the board. Here is link to manual close to your unit:

Scroll down to near bottom and wait for "download your manual" in lower right corner. Click to download. This is the 131 model but should be VERY similar to your unit.

My yamaha ydp-160 sounds like my pedal is stuck down. All keys are sustaining all notes. Is there an easy fix?


On SOME Yamaha pianos, there is an electrolytic capacitor 1mfd/50v that becomes leaky and causes this. On those with the particular main board the capcitor is at location C94. On other pianos there are other caps that bypass the wire from the pedals that are ceramic. Likely one of these has shorted. There is also a possibility that the pedal contact has shorted. Test for this by unplugging the pedal cable. If it still sustains, then problem is internal. Unless you are adept at electronics this is NOT a DIY repair.

Ydp 223 some keys are starting to stick to on the downstroke when not struck with a perfectly vertical stroke. varying degrees of affliction. instrument 2 years old thanks for any help


Yamaha keyboards can be prone to sticking keys due to the rear part of the key cracking around the return spring - if this is the case the only solution is replacing the affected key modules. However this problem generally only occurs with long term use by very physical players.
Otherwise the problem may be caused by a build up of dust / fluff between adjacent keys - try raking out the spaces with a thin piece of fairly rigid plastic (maybe a credit card might work?)
