"Clacky" keys on SX900/700: Please send me your Serial numbers!

[hans1966]

Hello Friends, I am very happy because you fixed my beautiful SX900.
luckily i got a good deal with yamaha service man.
so I already have a new keyboard , and I think for 5 or 6 more years.

what a bless. I couldn't imagine living without this precious machine.

Hello Enildo, I suggest you make a good deal with the technical service of yamaha brasil.

since this is not really serious damage and can be fixed.
I hope everything goes well friend.
Regards.

Hans

Hello to everyone here on the forum!

I have good news: Yamaha contacted me to take my SX900 to technical assistance for repairing the noisy keys.
Upon arriving at the service, the technician informed me that Yamaha Brazil got in touch with Yamaha from Japan and decided to carry out the due repair.
The SX900 will remain in service until the "grease" arrives and the service will be performed.
I want to thank Yamaha for the attitude.
I complain when I have to complain, but I also know how to praise when it is necessary.

Back to the days of romance with Yamaha!

Thank you, Enildo, for this report!

I'm happy that our close contact here in Germany with Yamaha Music Europe (based in Rellingen / Germany) has contributed to the fact that this "clacky keys" problem now will be fixed by Yamaha (also in other countries) on guarantee.


Best regards,
Chris

Same here in UK. No problem.

Hi Chris!

I want to thank you for your efforts and that of others to bring this problem to Yamaha. I'm sure it was the effort of many.
Here in Brazil I did my part, contacting yamaha and putting my mouth on the trombone!

Hug!

I'm happy for you... good music Enildo...

Hello,

I own my PSR SX900 for 2 months now and the black keys are clacking more and more every playsession. Especially the black keys that are pressed often in the middle of the board.

Is there any instruction how to open the keyboard and apply new grease. Any video out there. If I do it myself, I need a very good intruction, because I never did this before. Is there any link to original Yamaha grease (Buy).

Best regards
Bene

[EileenL]

Always best to let Yamaha do it for you. If you damage the keyboard in any way whilst doing this it will void your warrantee.

[Toril S]

Eileen is right!!

[samhodgsonpsr]

Hi everyone,

I finally received my PSR SX900 back last week. Worryingly, after only a few days of usage, the black keys have started to 'clack' again (more noticeably in the fourth octave where I must play the most). Included in the box was a receipt from E&M Electronics Services, stating that the keys had been re-greased. Perhaps again the wrong type or amount of grease was used. I have now decided to raise this issue with Yamaha directly.

Best wishes, Sam

[EileenL]

Mine was done by E&M quite a few weeks ago and I believe they now do most of Yamaha's repairs.
  Have not had any more trouble with my keys so far.

[LaHawk]

Before your warranty expires, contact Yamaha support and let them know of your problem. They will issue a case number.

Mine was done at a local authorized Yamaha dealer/repair shop. The shop ordered special grease from Yamaha, and repaired it in one day.

Before the ordering of grease and doing the repair, the shop was in contact with Yamaha to insure Yamaha would pay for the repair. They did.

Keybed keys are perfect again, with no clack. Attempting self repairs will most likely void the warranty.

[Leading Edge]

I was seriousy considering an SX900 but having read this topic I've had a change of heart.  I don't need all the hassle that accompanies a new SX900 if you're unlucky enough to get one with a faulty keybed.

[Toril S]

Same here! But I have the Genos. Wonderful keybed, stable and good! Same with Tyros. My S975 is clacky, but not in a faulty way, it is how it is, and being an accordion player I don't mind.

[Leading Edge]

An interesting reply Toril.  My Tyros 4 is over eight years old and had a very hard life.  The top of the keys are wearing from use but it still works perfectly. 

So what went wrong with the SX?   It appears to be a definitive quality control issuse whether that be in the manufacturing process or a design fault.   I'm no expert but it appears from the earlier posts either a cheaper product (grease) was used or it was applied incorrectly.  Maybe they should, if they can, issue a list of affected serial numbers and then potentential buyers could be assured they have the option to purchase an SX without this issue.  This assumes they know the S/N's of faulty keybeds or have not recalled the SX's with the fault that had not beed already sold.

In the meantime, I'll continue to mull over what to buy next.

[EileenL]

The SX900 is a great little keyboard. I had one of the very first ones out. I did have problems with the keys but got in touch with Yamaha who arranged to have it picked up and sent to there official repairers. It was then sent back to me and is now working fine. Mind you the keys did not make that much noise. Much less than the PSR970 in which all the keys were noisy.

[Leading Edge]

It's good to know Yamaha take care of the problem of the faulty SX keys.  However, as I said earlier, 'I don't need all the hassle that accompanies a new SX900 if you're unlucky enough to get one with a faulty keybed'. 

Thank you for your kindly response Eileen but, on that basis, I'll take a pass on an SX900 and look for a different back-up keyboard.

[Bene]

Yes, I could contact Yamaha. But then I would probably have to send the keyboard away. That would be expensive, because I would have to buy a box and pay for shipping. That costs about 70 dollars. I'm from Germany and we only have one Yamaha Motorcycle store in our city. I doubt that they can help me.

One day the warranty will expire and then I need to know how to add grease to the PSR SX900. Even in case Yamaha doesn't accept the keyboard.

Thank you very much!

The user "computec1349" already did this process. Maybe he can give us a short manual how to open up and add grease. He said synthetic grease would be perfect. He attached pictures.

[LaHawk]

 I must say if I hadn't read about it, I wouldn't have even noticed the so called "clack"  or side movement.

The repair center said it seemed fine before the repair, but since Yamaha was paying for the grease and labor, they went ahead. And Yamaha USA has stated this is not a known problem, but are willing to make concerned customers happy by changing the grease, no charge.  That's what I did.  So in no way would this stop me from buying a new SX-900. It's a great keyboard.

Hi
I have added extra Yamaha key grease to mine as I did not want the hassle of sending it away.
As a engineer the task was easy for me and took less than 1 Hour to complete.
I used Yamaha key grease which comes in a syringe.
There is also a synthetic grease I have used in the past by Dow corning  which is Molykote EM -30L which is white and has the same consistency as the Yamaha grease and is for plastic parts.
I would not recommend anyone without some basic skills in this area to carry out the service as there are a lot of ribbon cables around the keyboard assembly.
Regards Peter

Hallo,
I hope to buy a SX700 very soon. Seen a lot of reaction on the 900. Are there also these problems known on the 700? I'm in a little doubt now about the SX-series...

Hello ladies and gentlemen!

I am bringing the latest update regarding the noisy keys on my SX900, luckily the problem has been solved by Yamaha.
Despite the company's initial stance in saying that it was not a defect, I want to thank Yamaha for the attitude of calling on customers to do the due repair.
Now I'm happy and I hope that this problem doesn't come back.
According to the technical assistance, all the keys received a new grease.
The service was carried out under the product warranty at no additional cost to me.

A hug to everyone!

Thank you for the update on your SX900 keyboard problem.   

Whilst most of this series are satisfactory it does seem there are a few SX900's that have this issue with the key action.

I also want to thank, in particular, the forum members who also participated in this repair process.
Thank you the size of the world !!!

Tomorrow it will be 2 months since I bought my sx900 and, unfortunately, today, out of nowhere, he started to give problems on the keys, making a noise of springs, which bothers a lot ... very sad ... brand new keyboard, nor left home yet (because of COVID-19) ... and it already has a problem ... really sad!


Original text: Amanhã fará 2 meses que comprei meu sx900 e, infelizmente, hoje, do nada, ele começou a dar problema nas teclas, fazendo um barulho de molas, que incomoda muito... muito triste... teclado novíssimo, nem saiu de casa ainda (por causa do COVID-19)... e já apresenta problema... muito triste mesmo!

[Joe H]

This makes me very hesitant to upgrade to a sx900.  Maybe I should wait until the next sx model is released.

Joe H

[Leading Edge]

I'm having the same thoughts too. 

Surely later models won't be shipped with same problem!

[samhodgsonpsr]

I cannot recommend upgrading to the PSR SX900. Having done so myself I have had to return the instrument for repair multiple times and the same fault develops over and over again. I purchased mine in July this year. Other than the keybed itself, the build of the SX900 is very good. Some users will not have this issue, but I think it is fairly widespread so I would wait until the next model.
