The F# was definitely louder than the other black keys on the SX900. 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. It would be awful if something was damaged in the process. 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). 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. 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.Įnildo, I am sorry to hear that you are having problems trying to get your instrument repaired.
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 have just re-boxed my SX900 and it is being sent back to my dealer tomorrow. Sam do you like "uncle" Rodger's songs? I think they are brilliant The rest keyboard players should not open a new keyboard in any case. 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.Īnyway, 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.Ĭomputec knows a lot about keyboards so he could fix this by himself. The F# on Sam's keyboard sounds louder than Eb and all the the other black keys.Īlthough I would rather test the key without my finger leaving the key at all and not by hitting it. 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). 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.īut all black keys produce almost the same sound,a kind of more metallic sound than on Sam's video.
It really is disappointing that these expensive keyboards are developing faults after such a small amount of use. Īnyway, whether I receive a repair or replacement unit I will keep this thread updated if there are any more developments. Here is the link to the product specifications of that instrument. 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). 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. The keys on my unit sounded fine for the first few days, but gradually got louder.
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). I am returning my SX900 to my dealer for inspection and hopefully a repair. 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 have filmed a video for my dealer that shows the problem.
