Yamaha S08 D key sticking

by Mario
(Wisconsin)

I have an S08 which I purchased about 7 years ago with a D key that just recently started sticking. It operates fine but when I hit it it won't come back up. Is there a way to fix this myself or am I going to have to take it to get serviced?

Sticking key
by: Dick Rector

Hi,

Try a can with compressed air and blow on all sides around the bandid keys. Then a vacuumcleaner on it!
Most at the time it is dust building up over time.
I had also good result, and adviced it a few times on this forum, with a littlebit of talcumpowder (babypowder)blowen on all sides and under the key. Talcum works as a dry lubricant.
WARNING HOWEVER! NEVER but NEVER use any lubricant on an oil-base. That will guaranteed be the end of your keyboard!!
Let us know please if this helped solving the problem so others can learn from it.

Regards
Dick

Hello,

You better try your nearest dealer.
We don't have anything to do with a factory so numbers of parts is difficult to get on the forum. A dealer might have a 'dead' keyboard and uses it for parts. If you are lucky you can get a replacement key.

Sticky Key
by: Elijah

My church has the S08 and we have a couple keys (important ones, maybe E4, D4?) that are sticking.
Anyway, I'll try the compressed air and vacumming and let you know what happened.

sticking keys
by: Anonymous

I had two keys stick C2 and middle C. I opened the keyboard up to see what was going on (I own the S08) and found that the key was cracked where it attached to the weight, it was causing it to ever so slightly favor the left side in turn made the key stick, So I switched the broken one with a non cracked low C and it fixed the problem.

Hi Anonymous,

You must have forgotten to give a name and I almost NEVER react on noname messages.
Great you could replace that key, alas not all people are as handy as you. For them we always advice to get help from a prof.
But if you feel like it and want to be a help to other people with the same problem on a S08, would you mind to describe the process of changing the key a bit more detailed.
Thanks in advance.

I had same issues with sticking keys
by: Jim

I have had an S08 for about 8 years now. We had a small church which we had to build and tear down the audio equipment after each use.
I packed my keyboard in a hardcase and would store it vertically.... bad idea!
After time the weight of the kb and the pressure of the lid put strain on the keys and made them stick.
I took the kb apart and found that a lot of my keys had cracks on the top of them.
I was able to fix it with super-glue. Also, replaced the mid-range keys with the non-broken keys in the upper and lower octaves... Same keys!

That might be an idea for you who have the same issue.

How to remove the keys... once you get the cover off and are looking at the keys hammer action, you have to stick a small thin object long side of the key toward the top of the key.. i used a butter knife. There is a kind of leaf spring that needs to be depressed. Once pressed, slide the key out toward you. Give it a shot! Hope this helps.
Oh an an entire replacement key set is an arm and a leg... literally!

Hi Jim,

Thanks for your advice about this. Always a great help to other people with the same or similar problems.
You are right, in general replacement parts are very pricey (if you can get them at all!!)

S90 trouble
by: D-less

Yes thank you - my S90 has a D6 sticking. I have disassembled the keyboard but I dare not remove the keys themselves. all springs and parts seem to be ok. very little dust is present after 8 years. if it is just ,why only the D?

Sticking D's
by: Rick

Our school has a S08. A student fell into the keyboard and messed up a D key. I took it apart, and swapped a less used D for the broken one. Long story short: Now all the D's are broken now. The pivot point works like a ball & socket, but the socket's plastic is too thin, or too brittle. Once a small piece breaks, the key will lean a little and start sticking. I think it's a bad design. Why should we pay a premium price for a bad design replacement? Hmm?

Broken key?? Bad design?
by: Dick Rector

Hi Rick,

First of all, keyboards are not designed for students to fall on. So your comment about a bad design if a key is broken is misplaced. If you knew what you are doing by changing the keys around, you should know that when all keys of a kind are not working it is most likely that the rubber contact-pad is now broken or misplaced. I am not in any way connected with Yamaha or any other factory but your comment has nothing to do with a bad design. Many thousands of people around the world are very happy with their keyboards.

Under warranty
by: Rich

Hi all,

I had this same issue last year, and although I had purchased my keyboard in 2003, Yamaha replaced the entire set of keys for me at no cost as long as I had the original receipt. Just call them and explain.
