Title: "Clacky" keys on SX900/700: Please send me your Serial numbers!
Post by: overover on May 07, 2020, 12:08:26 PM
Hi all,

Frank Steinbrecher ("frankmusik") and I want to help users who have problems with "clacky" / clattering keys on SX900/700 models.

To do this, we need the Serial numbers of as many affected SX900 / 700 models as possible.

For details please read this post:

https://www.psrtutorial.com/forum/index.php/topic,54823.msg431608.html#msg431608


Thank you very much for your help!

Best regards,
Chris

With mine its just sharps/flats that are a tad noisy ...but can live with that.

IMHO the SX900 is better than any other PSR keybed i have had...although I am not a fast pro player. maybe even moving more to Tyros quality for me ... I suppose it depends on your needs.
Having owned MUCH noisier boards I remember it being a huge improvement when Ringway changed over to Fatar boards.

As said ...I dont feel it's an issue needing attention... well not in my case

Yes, Keith, it's mainly the black keys. And probably it mainly affects SX models of the first batches (however, relatively few devices).

Frank has already sold a lot of SX models, and he (except for the SX900 from Heidrun) had NO case where the keys would have rattled.

Basically, the new developed "FSB" keyboard of the SX models is definitely a big improvement over the PSR-S keyboards.


Best regards,
Chris

Dear Chris

The keys the SX-900/700 uses are the same keys that have been used since the PSR-1000 was released, even the part numbers are the same. The noise of the keys is due to the premature wear of the grease inside. Even if you change the keyboard 10 times sooner or later, this problem will come, depending on the time the instrument has been in use, so Yamaha will not replace it, they will even tell you that it is because of the use of the instrument.

Cheers

P.S. I worked in a service center and that was the response that Yamaha asked us to give to our customers.

They might be the same keys but there's definitely some mechanical change in the new FSB keybed with an increased key travel. My older E413 that has been abused for 10 years doesn't have the issue. It's still intact and there's absolutely no rattling sound.

I suspect this is either a poor industrial design with the action mechanism by Yamaha themselves or a bad manufacturing (Quality Control) issue considering how inconsistent the rattling sound is across the board.

Hi Chris,

Yes, it's only the black keys. I don't consider it as "severe" in my case but the rattling sound is still there. It concerns me more especially when I compare my SX900 keys with my older E413 keys. There's absolutely no "clacky/rattling" noise on my E413's keys.

Very well could be a quality control issue with the first few batches since Yamaha has to ramp up the production to flood markets/stores.

My SX900 was apparently (according to my dealer) the very first sale in the entire country - since I order within minutes of SX900's announcement in my country. Should've waited perhaps? Couldn't contain my excitement at the time lol.

Hi Guys, I just realized that my SX900 also has that Click or rattle on some black keys. although as Christofer and Keith say, it is a bearable noise.

Hi Chris, if I send you the serial number, will they change my keyboard for a new one? Or is it just to have a report of the SX with problems.

The E and MX and MODX keyboards and the S670 use the same type of keyboard, it uses no grease and is more durable.

It looks like most of you want a new keyboard, right ?

Do not expect your present keyboard will be replaced by a new one but it will be repaired ( free of charge ) by one of Yamaha's service centre's, IMO. 

Remember the PSR S900 screen !!!

Good luck !

Hi,

I tend to agree with you but not completely.  IMHO the E series had a nice keybed up to the PSR E343 and PSR E433. Form the E353 and E343 onwards, the quality is not as it was. I played the E463 and I didn’t like the keybed at all.

As for the lower S keyboards, I think the keybed was nice up to the S650.

I think keybed were better in the past because these keyboards, at the time, were med to be more durable.

Vinciane.

It seems like the number 900 is a curse for Yamaha. How many keybeds will need to be replaced on the PSR sx900

It's a shame that there have been so many bugs on the sx900.  Maybe I'll wait for the next PSR sx 9xx to see what's been changed/improved.

Hi computec1349,

I have to contradict you here unfortunately.

I checked the relevant service documents: The PSR-550, 640/740, 1000/2000, 1100/2100 and 1500/3000 models have identical keyboards.

However, the FSB keyboard of the PSR-SX700/900 models is completely different (see the attached picture).

I am sorry to contradict it, but the function is the same and both models still use grease, the "crash" is because the grease is very thin and when the instrument is used a lot it dissolves, in the image in the part-list the grease is noted.

Don't shoot the messenger... obviously there is a problem. On a $2000 keyboard this is unacceptable. If there is no noise with the white keys, then it should be the same for the black keys. Yamaha have been building keyboards since the 1960s.  They should know how to do it right by now.

Hi computec1349,

thank you very much for pointing out that the problem could be the key GREASE.

Yes, you are right here: There is also used some GREASE with the SX900/700 "FSB" keys. But it's a different specification of grease, called "GRISE BLUE G-1066Y 16KG" (see attached picture).


And to be complete: Also the other Part numbers of the new developed "FSB" keys differ from the "old" keys used in e.g. PSR-1000.


Best regards,
Chris

Dear Joe H
I'm not shooting the messenger. This forum is for conversing with colleagues who have in common the use of Yamaha keyboards, as I mentioned in the previous post, I worked for an authorized service center, and all PSR-1000-3000 keyboards and the S7 and S9 series have had that detail with grease, several customers reported the problem, but Yamaha's response was "It is a problem of use of the instrument, wear, therefore there was no guarantee"; Customers ended up wasting time and paying for review. So what I recommend is that you let the warranty period pass and when I finish I can advise you to replace the fat with a better quality.

Regards.

The contributions of those who apparently have in-depth knowledge about this (technical) subject are instructive. As a forum, this can be of great benefit. You don't have to agree with each other, but arguing based on knowledge, experience and facts just belongs on a forum. In my opinion, the discussion is conducted well, with respect for each other, thank you for their contributions.  ;)

They made an advertisement saying that the SX900 had the Tyros4 keybed and a lot of people, just like I believed.
To my unpleasant surprise the black keys started with this noise. I hope you fix this!
It is the first time that I experience this type of problem.
I've had a Psr 510, 520, 540, 3000, s910, s950, s970 and s975 and none of them had this defect.

I just compare to my old yamaha HS8 electone, the keybed on hs8 has no noise at all even aged 32 years old.
I also found the black key on sx900 are thin in construction compare to HS8 when I click it with my finger. And it has more left-right moving room than my previous technic kn3000 and Korg Pa700.

Those with "clicky" black  keys should contact Yamaha. You'll get a case number, and a good chance your key bed will be repaired or replaced. Do this before your warranty runs out to avoid charges.

for me PSR-S series keybed is the ultimate keybed, better then any keyboard or midi controller, for me it’s just the perfect keybed.

My greetings to all the ladies and gentlemen of this forum!

Last Thursday, I took my SX900 to the Yamaha service center in my city, so they could take a look at the problem of the noisy black keys. Upon arriving at this location the professionals refused to receive the SX900, claiming that this was not a defect and that the yamaha had changed its keys, to this new standard and this would be happening with several models. I argued that when buying the keyboard and when I tried it in a store, before buying, the SX900 did not have any abnormal noise on the keys and was shown to have very good quality keys, but the problem arises after use for more than 30 days, on average, characterizing this an addiction (long-term defect) in the structure of the new keys adopted by yamaha. Before heading to the technical assistance, I sent an email to Yamaha Musical do Brasil, which was answered almost automatically, saying that I would take the keyboard to the nearest authorized Yamaha service. When I was in technical assistance, I explained that this defect was happening with several SX900 keyboards in various parts of the world and contact was made with Yamaha Musical do Brasil, by phone, by one of the professionals, reporting the problem, and to to my surprise the brazilian Yamaha said that it was not aware of this problem and that i was the first person to seek technical assistance reporting this fact. The technical assistance recorded 2 videos showing the noise of the keys and said that it would send to Yamaha Brasil. They also took my phone number and said that "probably" Yamaha would call me, which so far has not. It already has several yamaha keyboards, including cheaper models like the PSR 540, and this is the first time I have bought a PSR with poor quality keys. A music colleague who bought an SX before me, has the same problem. I demand the exchange of all the keys, or replacement of the SX900 or I will file a lawsuit asking for my money back, because if I knew that the keyboard had this problem I would not have bought it. If you intend to buy a SX carefully, this defect will appear after you purchase it with use.

Just to feedback on this issue Enildo .....as noted on my earlier post, it was not a real issue to me and the 900 seemed ok despite the slightly noisy sharps and flats. Although I have to add I am unable to comment if this would have got worse with wear.

I recently traded down to a new 700 ( which is really in essence the very same board ) and have to say it's just fine, the sharps and flats seem to operate very well and just as good as the white notes.

I will wait for Yamaha to contact me to solve my problem, in the next few days, if they do not contact me,
I will send another email and also make a video showing this problem on youtube, to alert other possible buyers of the SX900.
I will also make a complaint on the website "Reclame aqui", which is a Brazilian website for complaints about bad products and services, much visited in Brazil.
And if all this is not enough to solve my problem, I will file a case in the justice of my city.

I spent almost four years with the s970 and it didn't. With the SX900 it was only 3 months and the keys are already noisy. If a good grease is needed, let the yamaha take responsibility for the maintenance in your authorized workshops, as the instrument is still under warranty and does not leave the responsibility of the owner.

Even if I want to use a good quality grease, I can't, because when I open the keyboard, I lose the warranty. This is what is wrong, it is not my responsibility but the company's. If, when I tried the keyboard, the keys were already with that noise, I would be buying already knowing that it would be like this, the problem is that when buying, the keys were perfect and only afterwards they show that they are of poor quality.

do all the sx keyboards eventually develop this problem, or only some? Ie is it thru wear and tear, or develops over a period of time.
I haven’t noticed it on mine, because I rarely use the sx keys , I use my p121 piano as a controller.

Hi Rikki,

with the help of Frank Steinbrecher (frankmusik) and Yamaha Music Europe, based on the serial numbers, we checked the production date of many SX keyboards (worldwide).

Basically only very few SX keyboards are affected by this problem ("clacky black keys"), and we found that all SX models that have been reported to us so far come from completely different production batches / production dates.

We have already discussed the problem with Yamaha Europe. At the moment it looks like the reason for the problem is the key Grease used  (that is applied between the moving parts of the keys). In some cases, this Grease was apparently applied too sparingly.

We recommend that affected users directly contact the Yamaha representative in their country, e.g. via the support form on the local Yamaha website. The ideal thing would be to record a short video (with sound), in which you can see and hear the "clattering" of the keys, and to send this video to Yamaha Support via email.

Normally, an affected keyboard should be repairable by Yamaha within a short time. A complete replacement of the keyboard will only be necessary in very rare cases.


Best regards,
Chris

It only happens on the black keys as some have quite a lot of side to side movement and will make a little more noise than the white keys. If it dose not worry you then you should not worry about it.
  Probably people who play very softly or use head phones will notice if they have it.

Hello everybody!
I made a call to yamaha Brazil on the 21st and yesterday they sent me this answer:

Dear Mr. Henyldo,
Yamaha Musical thanks you for contacting us.
Thanks for forwarding the video for a more accurate analysis by our technicians.
After detailed analysis, the technicians identified that this is a characteristic of this key system and there is no non-conformity in their product.
If you have any questions we are available.


I am very sad with Yamaha, because to say that this is normal, is to want to push down a defect in your last PSR product.
If this noise was perceived right away when buying or testing the instrument when new, fine, it would be up to the customer to decide whether to buy it or not, but the problem is only noticed after use for a few months and see that I didn't even have time to play at my events because of the pandemic. I wonder when I use the keyboard for real, playing 2, 3 4 hours straight. The teco-teco (noise) will be great! Then the keys will loosen for good.

My opinion is that they don't want another "PSR900 Recall"... remember that screen failure? They must have replaced thousands of screens under warranty.  They don't want to go through that scenario again.  It could cost them a bundle of money.  Someone at Yamaha messed up with the new key bed. Either it's poorly designed or the wrong kind of grease.  In any case, it's unacceptable for a company that has been making keyboards for 100 years or more. It's like their launching of the Genos and now the free download website. Both have been a mess!

Maybe its a case of the next generation engineers and marketing folks.  The quality of so much of the physical/hardware merchandise is declining... and maybe; so are the people who produce it and market it.  As a person who has been business for 38 years, the quality of workmanship and service has declined everywhere I look.

I have a colleague with the same problem with the SX900, he lives about 25km from my city, I think many people will appear. He will also take the keyboard to the authorized service. I will send another email to yamaha responding to this negligence, and if they insist on not repairing my SX that has only 5 months of use, only at home for short trials, I will judicialize the issue. I think the company is silly, because they spent money on lawyers and in the end I am sure that I will win the cause + moral damages for not having done their role of respecting the guarantee of their products.

Hello everybody!
I made a call to yamaha Brazil on the 21st and yesterday they sent me this answer:

Dear Mr. Henyldo,
Yamaha Musical thanks you for contacting us.
Thanks for forwarding the video for a more accurate analysis by our technicians.
After detailed analysis, the technicians identified that this is a characteristic of this key system and there is no non-conformity in their product.
If you have any questions we are available.


I am very sad with Yamaha, because to say that this is normal, is to want to push down a defect in your last PSR product.
If this noise was perceived right away when buying or testing the instrument when new, fine, it would be up to the customer to decide whether to buy it or not, but the problem is only noticed after use for a few months and see that I didn't even have time to play at my events because of the pandemic. I wonder when I use the keyboard for real, playing 2, 3 4 hours straight. The teco-teco (noise) will be great! Then the keys will loosen for good.

Enildo  >:( >:( >:(


I had told them, but they ignored me. Yamaha that's right ...

It is nonsense for Yamaha to just claim it is 'normal'. It's possible that it occasionally happened with Yamaha keyboards in the past, or that some very small - hardly noticeable - amount of movement is 'normal'. But what people are saying here cannot be 'normal' or we would have seen many posts on this long before now. And it just so happens all the the complaints are about the same model  ??? ??? ??? - sorry Yamaha but engineers don't believe in that kind of coincidence. I never noticed it on any of my Yamaha keyboards including my old psr3k, and believe me I would have noticed if it happened. It has to be a manufacturing or design difference. If they make the keyboard with too much free play in the keys, maybe they can cover that up with new grease - for a while. But as people are seeing here, ultimately it will show up.

Is there any video or at least anυ audio example to hear how much noise the black keys are producing compared to the white keys?

Computec's explanation looks pretty logical.
When there is a friction, there will be a noise if there is a problem with the grease.
There must not be any annoying noise produced at all by the keys of a keyboard at the level of the psr SX900.

Friction is unlikely to produce the kind of noise and movement people describe. That most likely comes from 'play' in the key fixing point.

After owning my PSR SX900 for ten days (an expensive 18th birthday present that I bought for myself), unfortunately it has developed this issue, it has appeared on the keys I use most. I have filmed a video for my dealer that shows the problem - https://www.youtube.com/watch?v=zv2NoQyn7VI . Before this issue surfaced, I viewed this thread so I believe I was more paranoid than I would have been otherwise, this allowed me to notice the issue quickly. I am returning my SX900 to my dealer for inspection and hopefully a repair. I am starting to think that this issue is more widespread than previously thought, my dealer mentioned sending a replacement to me and I believe there is a real chance that the same fault would develop so I really would prefer a repair (a reapplication of the correct amount of grease). The keys on my unit sounded fine for the first few days, but gradually got louder. Having previously owned a PSR S750 for 4 years, I admit the keys weren't silent, there was some noise because it had seen a fair amount of use but it was nothing like the noise on the SX900.

In terms of the keybed itself, I am aware that the Electone STAGEA ELB 02, (an electric organ produced by Yamaha that is only for sale in certain regions) has an FSB keybed, whether this is the same one used in the PSR SX700 and 900 I am not sure, but it is possible that the keybed design has been in this ELB 02 (released in 2016) which would make this issue even more puzzling (if Yamaha already has experience with this keybed). Here is the link to the product specifications of that instrument - https://asia-latinamerica-mea.yamaha.com/en/products/musical_instruments/keyboards/electone/elb-02/specs.html#product-tabs .

Anyway, whether I receive a repair or replacement unit I will keep this thread updated if there are any more developments. It really is disappointing that these expensive keyboards are developing faults after such a small amount of use.

After seeing that Yamaha will not do anything like the previous keyboards, I made the repair myself.

As I said at the beginning of this thread, it is a problem that has been around for more than 25 years.

The solution is to replace with a grease of higher density and quality.

And fixed my keyboard like new and for at least about 15 years.

No one should have to take a relatively new keyboard apart and change the grease. The SX range are not cheap toys, it should not be happening, and taking it apart might affect the warranty. And many purchasers of these keyboards are in their  ‘twilight’ years. They bought these keyboards  to  play music, not become technicians.

Here in Brazil I'm fighting with yamaha to repair my keyboard under warranty. Fortunately we have the consumer protection agencies that I will appeal to. I will want an indemnity for moral damages due to the denial of the repair, which is the obligation of the yamaha, within the warranty period.
I am not going to open my keyboard to do the repair myself, because it will void the warranty if it gives another defect.

Hi Perro!

I used synthetic grease for electronic components, you can find it in electronics stores, it is white and it is placed in the new black ones at the end of each key.

Post by: panos on July 29, 2020, 06:08:21 PM
If I hit the black keys on my s750 the way that Sam did a little different kind of sound is produced which is also noticeable.
But all black keys produce almost the same sound,a kind of more metallic sound than on Sam's video.

White keys produce just a little normal sound (if you hit a plastic with your fingers I guess is normal to hear just a little sound).

The F# on Sam's keyboard sounds louder than Eb and all the the other black keys.
Although I would rather test the key without my finger leaving the key at all and not by hitting it.
In order to hear the sound by key itself when moving up and down and not the sound produced between my finger hitting the key.

Anyway, let's hope there will be a solution to this as long as people saying there wasn't such noticeable sound when the keyboard was bought..

Computec knows a lot about keyboards so he could fix this by himself.
The rest keyboard players should not open a new keyboard in any case.
 

Sam do you like "uncle" Rodger's songs? I think they are brilliant  :)

Hi everyone,

Thank you all for your replies.

I have just re-boxed my SX900 and it is being sent back to my dealer tomorrow. First of all computec1349 I agree with you completely, noise has always been an issue on PSR S series keyboards, but at least in my experience an issue hasn't appeared this quickly. I really commend you for applying grease yourself and am a big advocate for the DIY method(I own a computer recycling and resale business), it is fascinating to me to see why this problem is occurring in the first place, it seems like a trivial manufacturing mistake to me! Maybe with your help we can devise a repair guide for other users facing this issue although I agree with Mike that nobody should be expected to dissemble such a new keyboard to rectify the issue.

Enildo, I am sorry to hear that you are having problems trying to get your instrument repaired. Having seen your previous post on the thread, I can't believe that the engineers say that there is no non-conformity in their product, I believe Yamaha should honour the warranty. As an advocate for the right to repair movement, I really don't think it would be fair for a warranty to be classed as void for reapplying grease to the keys but I understand that most people wouldn't feel comfortable opening up such an expensive and complex instrument (although it isn't that difficult to do). It would be awful if something was damaged in the process.

Panos, I owned a PSR S750 before this instrument and remember that the keys had a noise when they were played, the noise was nowhere near as loud as the SX900, and it was much more consistent between each key. The F# was definitely louder than the other black keys on the SX900. After filming the video I noticed that most of the keys had a 'clack' but most of them were mild (but most likely would have worsened over time). The white keys on the SX900 were perfect for me. In terms of how I played the keyboard to get the noise to surface I admit I was playing the keys a little harder than usual (but nothing ridiculous) playing the black notes with a normal soft touch would reduce the noise but it was definitely still present. I first noticed the issue when practising a chromatic scale. My Yamaha Electone EL60's keys still sound fine, all consistent, even if the keys were played in that manner. I haven't heard of Uncle Rodger before.

Rich, I am more than happy for that link to remain pinned in your comment. I really appreciate you uploading that video in the first place! It confirmed that my suspicions that my keyboard had the same issue.

Hopefully within the next week I will have another SX900, and hopefully it does not develop the same issue. However I must admit I am trying to remain pessimistic about it.

Just as a matter of interest, have any SX700 owners faced this issue? So far it seems that it has predominantly affected the SX900.

Hi Sam,

https://www.youtube.com/watch?v=Mm6cPXSjdRs (https://www.youtube.com/watch?v=Mm6cPXSjdRs)

You had both the SX900 and the s750 so Ι guess you can tell in which point a noise of the keybed can be bearable and in which point it can be not.
So can Enildo and the others who owned a psr S model and now facing this problem with some SX models.

Hi Computec1349,
Enildo he is right, the problem must be solved under warranty ... and Yamaha must honor its customers. To me, for the blockage of the SX900 they said that I had to take it to the service center for repair (after 22 days from the purchase that answer is not acceptable ...) Especially when, with the release of firmware 1.05 Yamaha confirmed and admitted the existence of the problem.

As for the topic of the post, I am interested, why if this problem should happen to me, now I know what I have to do ... I also like to understand and tinker.

Last year I solved a problem without having to resort to assistance on a Samsung smart TV (no longer under warranty), modem had stopped working, assistance had said that a technician was needed and € 80 for replacing the broken modem.

The modem, was not broken .. There Was a wrong setting in the hidden menu of the TV ( Why? ... is a mystery, but I think, about it, an wrong of the Tv autoconfiguration), of course you need, to know, where to get your hands ... but the Web is a great help.

PS For Enildo: ...look your PM...

The update to 1.05 was nothing to do with noisy keys. There seems to be a problem that not enough grease was used on some keyboards. If you get in touch with your shop or Yamaha they will arrange to have it put right for you. Unfortunately these things do happen with a lot of things we buy today and with Yamaha they are put right quickly which is nice to know.

Hi Eileen,
Sorry, I thought, my post had been well translated by Google ... :o

I was referring to the problem of freezed the SX with the favorites, solved with 1.05. Yamaha Customer Support initially denied any intervention other than  repair. Today we know that the problem was real and resolvable with an update. Did Yamaha make a good impression? And everyone who replied me that, more probably, the motherboard had broked? nobody shared my opinion about the operating system bug ... yet this was.

Same thing for the grease and the noisy SX keys reported by several users. Telling a customer that the problem doesn't exist, when the problem exists and has been proven, is not a good commercial policy, not for a giant like Yamaha.

The service centers should receive directives from the parent company, to protect customers and not to deny to the problem that exists instead.
The intervention in this case, noisy key after a few months, must be done without delay and under warranty.

Have you read that Enildo has been told that the noise of the keys does not deserve the assistance and warranty?
Enildo's requests are right
Here in Brazil I'm fighting with yamaha to repair my keyboard under warranty. Fortunately we have the consumer protection agencies that I will appeal to. I will want an indemnity for moral damages due to the denial of the repair, which is the obligation of the yamaha, within the warranty period.

Yes this is very bad when people are told the wrong things. As far as I know all Yamaha Dealers and service department personnel are well instructed on all new products but we all know that for a lot of people it is easier for them to ignore things as it makes life easier. We are very lucky here in the UK as we have service second to none on our keyboards. The technical staff could not be more helpful if you have a problem and will go out of there way to help you. Yes there is a problem with the greases used on some  SX keyboards and if you have a problem in UK the keyboard is picked up and put right with no fuss.

I have the impression that some of the assistance centers in some countries believe that it is more profitable to repair an item that is out of warranty than to give assistance to those under warranty, where the economic return is certainly laughable and limited
(Covid likely to have exacerbated this "conflict of interest") ...
It is always difficult for the parent company to protect customers through third parties. This is fair to say in defense of Yamaha.
 PS I was thinking if there was a way to apply a light layer without having to disassemble everything, if a problem like this will happens to me before deciding to disassemble I would try to give a spray or using a thin brush with a dense and quality synthetic grease from above of the black keys ... but always out of warranty.

I think I saw a picture on here somewhere of a member that had taken top of off keyboard to access the black notes. It has to be a good quality grease and is carefully inserted into each black key.
  Be very careful if your keyboard is still under guarantee. I would not advise doing it yourself.

A shame that this happens "Click noise keys" on a new SX900 keyboard; especially a top of the PSR line one!
You wouldn't expect that to happen but I guess Yamaha's choice to change their type of key bed on the new PSR SX900's has initial issues on some. I hope they look into this before many more releases.

After contacting Yamaha in May, about the "clacky" black keys, they advised not opening a case. (weird answer) I shall contact them again today.

At about that same time time period, I also contacted a local authorized Yamaha Keyboard Dealer/Repair Store, who in turn contacted Yamaha.

Here is the Dealer/Repairs email reply to me:

Larry,
I checked with Yamaha and they mentioned that it could be a problem with the felts. They advised that I should open up the keyboard and check to see whether the keys are sitting correctly on the assembly.


This was May 13 2020 I will take him up on his offer to check it out, although, the felts could be the problem answer is a new one for us all. I will let him know of the "grease" problem before taking it in. I also want to be sure this is covered under warranty.

So I agree with the advise to first let your dealer know of the problem, and if they do repairs, they, the dealer should contact Yamaha about a fix and warranty coverage.

Hi Larry,

I do NOT think that in this case the problem are the (damper / key stopper) FELTS. You can test this relatively easily: If the keys are being pressed straight down (without exerting lateral pressure), and there is a clacky noise at the lower stop or when the keys are released (quickly), it could be due to the FELTS.

The clacky noises described here when the black keys (already in normal play) hit the side of the white keys next to them come, in my opinion, NOT from the felts, but either too little (or unsuitable) GREASE was used, or the keys have too much bearing gap due to a production / design error.


Best regards,
Chris

Yes the problem is with the grease not felts and not all of the keyboards suffer with this. It is probably only on the first few batches that came out first. The Yamaha engineers should put this right with no trouble but with this awful virus things are not all working as fast as they should.

Hi Chris,

Actually that is the case on my sx-900 . A barely audible noise on black keys when pressed straight down. It's on the quick release of the black keys when I get the clack noise. However I get somewhat similar results with the white keys pressed straight down, although not as loud, (more of a muffled thump sound) leading to my conclusion opinion that the black keys have

1. Felt problems, possible, and fixable
2. Lack of greese, also possible and fixable
3. Design flaw, probable and may not be fixable.

If it's a manufacture design flaw in some, and not all SX-900 produced keyboard, Yamaha needs to replace the keybed or the keyboard itself. However, we will never really know for sure, until successful diagnosis and or repairs are reported, utilizing an official Yamaha Repair Dealer.

Has anyone actually had their SX-900 clack noise problem diagnosed at an official authorized Yamaha Repair/Dealer?
And curious if anyone actually had their black keys noise problem repaired and working without the clack noise?
I'm calling soon to make an appointment at the local Yamaha repair dealer to have him  evaluate my keyboard, but first, I want to be sure I have the backing of Yamaha and the warranty.

Hi Larry,

thanks for your detailed feedback!

The white and the black keys of the SX900 both use the same key felts (Upper Felt = red, Lower Felt = purple in the attached picture). Maybe the black keys slightly touch the vertical area below the Upper Felt (marked with a green arrow in the picture) when the key is released quickly (?)

Chris

Hi everyone,

Though I would update you all on this 'clacky' key situation. My dealer promptly sent me a new PSR SX900 (this one was clearly re-boxed by Yamaha and had an EU plug modified for the UK included). After just a few days, the same problem has appeared. I am going to return the instrument once again and ask specifically for a repair this time. Hopefully this will actually rectify the fault for good. Unless I have had especially bad luck, I really do think this problem is more widespread than previously thought.

Mine is currently at a Yamaha Dealer/Repair shop, waiting for specific grease to arrive from Yamaha USA
The email response from the repairman:

Larry,
I heard back from Yamaha and they are shipping me the grease for the black keys. They did note that the new grease may make the key touch heavier at first, but as the grease fits in, it will become smooth.
I will let you know once I receive the grease and have finished the repairs.
Josh


Eileen, could you give an update on your repair please? Did you notice any difference in the touch, and has the noise returned at all? Thanks

I did direct both Yamaha and the shop to this forum topic, to help explain the problem and fix. Thanks EVERYONE for posting on this.

I picked up my keyboard today from an official Yamaha Dealer/ Repair shop.
He removed the old grease (seemed thin) and applied the new grease  supplied from Yamaha (seemed thicker)
He wasn't 100% sure, but suspects wrong type of grease, not enough grease, or it was applied incorrectly at the factory

But anyway, it's working great with no noise, a "smooth" key action, and he said it should last for many, many years, like a new keyboard should.

Here is a link to Sam Hodgson's "Before" video https://www.youtube.com/watch?v=zv2NoQyn7VI&feature=emb_logo (https://www.youtube.com/watch?v=zv2NoQyn7VI&feature=emb_logo) (hope that's OK Sam)

... I have filmed a video for my dealer that shows the problem - https://www.youtube.com/watch?v=zv2NoQyn7VI ...

I see a lot of side to side movement with the black keys.. Also someone said it's NOT the felt pads, but it sounds like the felt pads are not working nearly good enough.  Maybe they need to increase the size of the felt pads and a better fit on the black keys. In other words there is a need to improve the design for black keys... reduce the side to side play, increase the size of the felt pads, and use a better quality grease.

How could Yamaha have made such a mistake?

Hello friends!
Mine remains with the defect, getting worse every day.
Now the white keys are also beginning to appear with the noise.
Unfortunately, it seems that I will have to sue the consumer protection agencies. Yamaha Brasil is not giving due importance to the case.
I've already sent several emails, called, filled out a form on the site and they just ignore the problem.
If you are from Brazil and intend to buy one of these keyboards, be careful.

Having the new grease applied has stopped a lot of the side movement as well. You will always get a little side movement as the keys are not as close fitting as the white ones. This will also happen on Tyros and Genos keyboards if you make a point of gripping the note and moving it but that is not how we play a keyboard so dose not affect anything.

Hello Guys, since I have not yet recovered economically, I must postpone the shipment of my SX900 to the authorized Yamaha workshop, since this service is not within the warranty, and I must bear the costs of the material (grease) and maintenance. so I will have to continue with this problem until there is money to fix it.
The situation is increasingly difficult with Covid-19, and although I have some students for virtual classes, this is not enough to pay the costs of rent, internet, mobile telephony. hard work like serenades, masses, and social events, has been reduced by 95%.
I hope I will NOT have to sell my beautiful SX900 to pay off debt, and so I can survive.

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.

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! ;D ;D ;D

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

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.

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

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.

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.

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.

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.
Title: Re: "Clacky" keys on SX900/700: Please send me your Serial numbers!
Post by: Leading Edge on September 19, 2020, 07:44:40 AM
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.

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.

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.


Title: Re: "Clacky" keys on SX900/700: Please send me your Serial numbers!
Post by: Bene on September 20, 2020, 03:55:32 PM
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.

Post by: LaHawk on September 20, 2020, 05:23:36 PM
 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.

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.

But - Ironically the 700 i now own is fine.
not seen any comments re. this model, yet I assume it is the very same keybed as on the 900?

If the noisy keys develop again that means the problem is more than faulty grease.  Someone posted a video and I saw that there was a lot of side to side movement with the black keys.  Seems to me, this needs to be corrected (redesign the keys) and maybe also larger felt pads are needed as well.

Joe, I completely agree. To me there is clearly a bigger problem here.

I completely disagree. Not really a  big problem to begin with, and certainly no problem after the free service.

I’m hoping that my incident is unique but my SX900 has already been repaired twice and the same issue occurs after only a few weeks of usage. Here is a video just 3 weeks after the second repair was carried out (new grease and replacement key frame) - https://youtu.be/SEPzlqYiiqc . The keyboard is currently at E&M again for repair.

Thank you for posting the video Sam.  It gives a very clear indication of the issue when it occurs.  I hope, as you say, it's somewhat unique to your SX.  However, three failures including the key frame being replaced just weeks apart are rather concerning.  Maybe Yamaha should consider replacing the unit given the inconvenience it's caused you. 

Hopefully, the matter will be sorted out very quickly for you.   Yamaha's after-sales service has, in my experience, always been top drawer.

Thanks for your reply! This particular SX900 that has been sent for repair three times is already a replacement unit as the first one I bought also quickly developed the issue. So far my experience with Yamaha's after-sales service has been very positive.

I'm hoping that the issue will finally be resolved soon.
