It must have been dropped. Look to see if one side is bent so as to pinch the key. Gently pry it until it moves. Add lubricant if needed

Middle D key apparently was jarred loose in transport. It is sticking up and won't return to its original position, and playing the key produces no sound.

Call Yamaha at 714-522-9000 and ask for a tech who works in your area. Attempting self repair could void any garuntee that is covering the problem.

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?)

I have a yamaha PSR 240 and one of the keys (E) won't make a sound. Everything else works perfectly except for that. I could not find a category for yamaha keyboards or musical instruments.

Yep, a key contact has got contaminated... You have to disassemble the unit to expose the keys.

You have to remove the offending key which is OFTEN tied to a bunch of keys. Under the keys you will find strips of silicon rubber with little domes sticking up. Under the domes are two contacts, either two black conductive rubber or sometimes a ring with a pill in the middle. These contact circuit traces with a black coating on the board under the keys. Clean the pills AND the circuit traces GENTLY with ONLY 99% isoprophyl alcohol. Reassemble the keys and the unit.

Be very careful handling, especially the ribbon cables between teh upper and lower halves of the unit.

Note there are TWO contacts per key which one closes before the other and that is how the key velocity is measured by the processor.

Two of my keboard keys got hit by a child. They won't return to playing position. CLP-370

Hi there,
you'll need to open the keboard and check for the keys that has a missing mechanism on it. It usually is a stopper to prevent the keys from "sticking". You can use crazy glue or mighty bond to stick the broken parts together.

Hope this helps

Keys stick down after being played. I have cleaned, vacuumed, blown air throught he keys, etc. now change. I have taken the keyboard apart down as deep as possible and cleaned again, the keys still...

The key is to open the unit and find the exact point these are sticking. It is unlikely that vacuuming and blowing is going to improve the situation. Often the sticking is due to deformation of the case at the front draging the keys... This would be very obvious and I am sure you would have seen it and found this if it were the problem. It is not clear exactly which type of key mechanism is used here. I have several keyboard with various mechanisms. Some of the weighted ones are actually made by a single company and used by Yamaha, Korg, and several others. These are rather complex and probably not like yours. Others use a silicone rubber dome with conductive rubber contacts that press against circuit traces... for these, the restoring force is actually from the rubber dome. If the domes wear or deteriorate, then keys will not come back up. Yet another type uses a spring at the back end...M Audio uses this lightweight in some of their products.

In your case, I would look for a pivot point that might need lubricating. I was unable to find a service manual for the NP30 that would show the exact type key. I have several Yamaha keyboards that have several types of keys.

If the keys may be dragging on the side, clean with Q tips... and then you can wipe with a Q tip moistened with CRC226 available at Home Depot in the electrical dept. This is a safe lubricant for electrical uses.

Digital Piano has sticking key

Typically LOTS of screws... concentrate on those around the edge. USE GREAT care and force nothing when removing the cover...and great care of cables between the cover and the base. Mark the cables so you remember the direction they attach.

When you get edge screws out, then gentle lift and see where it seems to be held...

Some of these synths have 50 to take out to get apart. MOST are in plastic bosses and keep track of the size and length as you can put too long a one in the wrong place and crack the boss.

I use a compartmented plastic tray to keep the screws in order.

Keys sticking on Yamaha p120 digital do I open it up

you may not need to open it up.
try using a wax based furniture polish on the keys, it will leave a layer to act as a lubricant between the keys.
