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

[overover]

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:

Thank you very much for your help!

Best regards,

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.

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

[overover]

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.

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.

My PSR 2100 is 17 years old and the keys are like new. So what is happening here?

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.

[Christopher Fernandes]

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.

[shuey]

I have it too, but at the end of the day its just extra noise, not like the keys are are insecure or anything

[hans1966]

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.

[beykock]

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.

Regards,

Vinciane.

... Remember the PSR S900 screen !!! ...

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).

Chris

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. 

[Joe H]

... I'm not shooting the messenger...

Sorry I didn't know your credentials.

So... why hasn't this problem come up before on the forum.  I've been a member for 11 years, and also owned Yamaha arrangers for 30 years and never experienced the problem with noisy keys.

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.

[Totomo]

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.

[LaHawk]

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.

I hope people will take your advice... since you are a Yamaha dealer.

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.
