- The keys on my Yamaha P70 got too loud to stand. This video walks you through the repair process.
EDIT 6/13/2020: The parts for this keyboard can now be found at: syntaur.com/yamaha_p.html
Scroll down to find:
Keybed cushion, lower, for P35B/45/70/95/105/115 (Part #5297)
Keybed cushion, upper, for P35B/45/70/95/105/115/125 (Part #5284)
This is a much easier site to navigate than the one I mentioned in the video. - Навчання та стиль
just posted on part 1 but like to repeat on part 2. Following your videos has helped me to restore my p 70 so the action now seems like new. Thank you.
thanks for the shout out - I'm glad it worked!!
I have a P80 with the same problem. Watching your video gave me an appreciation for your level of patience and a yearning to buy a new keyboard.... LOL
Thanks Chris!! Yep, about a year ago, my P70 was starting to exhibit the same behavior on the same keys (can you believe c3, d3, f#3, g3,... lol) I thought about going in and fixing the pads and loose keys, but then quickly realized the grand piano sound (circa 2005) is really old. The sampling technology is so advanced now - so I bit the bullet and bought a Studio Logic 88 midi controller, Keyscape by Spectrasonics, and JBL Studio Monitors. And I have to say it's pretty close to an actual piano.
Your video helped me immensely. Mainly I needed to find out to open this up and removed the KB. I did find the Service manual free per your advice and managed to repair my sporadic dead keys problem. I found that something at sometime must have spilled into the keys puddling in the M board assembly; ...corroded the FFC cable going into the center M Board. I removed the cable and scratched with a razor blade a new trace contacts and trimmed the eroded former end contacts away. Next the FFC connection soldered to the M board had corrosion as well. I used contact cleaner and scraped what I could with a razor in the cable contacts. I would like to eventually replace this M board due to this issue and or replace the 27P FFC connect soldered. However, my efforts corrected the issue and I have 88 keys again! Thank you!
It's wonderful to see that you've taken it to the next level - that is far more work than I did!! Good luck on your future quests with P-70
Thanks for posting these videos. I followed the instructons meticulously and succeeded in getting my P-70 keys silent.
Hi. Thanks so much for this video. I have a p-60 that is clunking terribly. This will help a lot. Thanks for updating the availbility of parts! I called syntaur and got right through and got the part!
Thank you for making this video. I have an exact same P70 with exact same problem. I considered about upgrading to a more modern and expensive one, but this piano is my friend’s relic who died several years ago. So I have decided to repair it and keep it. Currently one of the part is out of stock in the website, but I will wait.
I have one P70 and want to repair myself. Same problem, parts is difficult to find. Do u think it is possible to use other similar materials to substitute it?
Just wanted to say thanks.. Followed your instructions and did the whole thing in about 1.5 hours. Although I also suspect that the grease in the keys/hammers needs greasing in order to really help with the noise.
you're welcome! I'm glad I could help you. grease is for squeaky stuff. the keys on my keboard don't squeak - they rattle. that means they're loose and need padding or tightening. that's a whole video itself.
I have a DGX 650, similar mechanism and felts. After changing the lower felt twice (the grey sponge ones) not much improvement, but then I decided to use a spare UPPER felt which I had in the replacement package (i.e, the red black and white 'liquorice allsort' looking strip) as a lower felt instead of an upper one, - and Bingo! - works like a new keyboard now. Zero clunking.
Ah... let the brilliant hacks begin! Nice!
You should use alcohol to clean the surface.
Great videos. Thanks again m8 !
LE: too bad you didn't do a test after replacing that ... I was really curious to hear how it sounds ... is it still loud ?
Thanks very much for this video! I am soon going to perform the same repair on a P115, which is very similar. Your next video topic can be about repairing the phone. ;-)
Good Luck! Remember to do it slowly and keep separate everything into their own bags or containers so you can remember how it goes back together.
I just bought a used DGX-650 It's about just one year old and the women told me that it was used just about 3 times by her husband before he died. It looks really brand new.
However, the keys are noisy, especially on the return.
They are all evenly noisy, then it's not wear.
I did not really noticed that before to be home.
How could it be possible?
Bad production defect or they are simply that way?
I am a bit discourage to see that we need to mismantle everything to change these paddings.
Are the DGX built the same way as the P series?
Thanks!!!!
i think it probably the factory issue, even those keys seldomly use also got noise. solution is using headphone or louder volume.
Many Thanks , very important to Know the keyboard parts store, there has been a fire at home and my p 115 was partially burned, luckily the electronics were not affected and I after a lot of work, I finally made it sound again, but the left part is destroyed and I need a new piece of furniture, I don't see in the articles, but I will ask them. I live in Canary Island. Chao.
I'm so sorry to hear about your keyboard. I hope you get up and playing soon.
Hey there, thank you for doing these videos. How did the Yamaha P-70 turn out after the repair? Thanks.
Shadrach thank you for watching! The repair worked and the action was quiet again for quite a few years. In the end, though, it returned and I think that is just the fault of the design. TBH, at that point I had the keyboard for 13 years, and technology had far surpassed the quality of the keyboard (i.e. the sample quality these days is just amazing) - so I gave the keyboard to my mom for when I come home to visit, and I moved on to new tech.
@@davidallyn1818 Ok then that's good. Glad it worked out. 👍
Great! Thx
Hi david: I think my P70 have the same problem, after watched your video ,I'd like to give a try. do you know where I can get the"pad"? thanks
ah, I got it, thanks
Thanks ever so much for this video. I have this exact keyboard, with this exact problem... After 6 months, the keys got so loud you can hear them down the hall, and good luck doing live vocals with this thing. Mine has a rattle, left to right as well as the clunk clunk clunk sound. Keys actually bounce on the rebound... Feels like I watched a clift hanger here -- Sooo.. did it work? How much did it help? Cheers,
Yes - please do tell how it worked out. And considering it's been a year how well did the repair keep?
Just a quick feedback please - was it worth taking the effort, did you rejuvenate the keyboard as much as you hoped?
7 months later: Having done this myself, I can say that it worked, but not as well as I'd hoped. I got the felt strips from Yamaha (who were really great), and did a full cleaning at the same time. The rattle is now about half what it was, but still about double what I hear in NEW versions of the keyboard. Not silent, but much better. When doing it, I noticed that there was a thick grease on a lot of the keys, so maybe that needs to be re-lubed as well. Thanks again for the video... it saved the keyboard.
+adiero Thanks for that info! Where exactly is / was the lube? I'll have a look when I take it apart. Also I don't expect this process to reverse actual wear - I guess there's some parts that just become loose and rattle themselves. It's just plastic after all and every glissando takes it's toll ...
+Armin von Werner Well said, "Every glissando takes it's toll", perfect name for an album! The lube was at the front of the keys. When dissassemble, you'll see that they're hollow and have a kind of plastic piston penetrating the tops. The lube is on the piston (keeping straight face)... really. And it attracts a tone of hair and dust etc. I think it affects the action as well. Still well worth the effort to repair, given the cost of the kybd, at least untill one can afford a better action (kawai m11? roldand d70?...)
I have another problem. The keys themselves aren't loud, but my G5 key half the time does not trigger the tone. All the other keys play their tone correctly. Any suggestions? Thanks! It's a Yamaha P-70 just like in your video.
Hi Brad, If I had to take a guess, I would say that the contact under G5 is either worn or corroding. The only way to tell would be to open the keyboard up (refer to video #1 - and the 70+ screws) and make a visual check of the place where the G5 touches a switch or contact ribbon. If you see any light-green powder in, on, or around any parts, then you'll need to replace those parts before G5 will work. The link above in the notes has a lot of replacement parts including the amp and contact strips. Good luck - that's a good one!!
@@davidallyn1818 I'll try to look at the contact, but I'm a little intimidated by digging too far into the unit. Thanks.
@@downbear It's not for the faint of heart that's for sure. TBH, I no longer have my P70 since it began to show another round of loud, clacky keys .... and I just couldn't think of making that journey again. I have a new keyboard that I love, and it was worth the upgrade!
Parts is hard to find now. I want to buy some material with similar texture or function to replace it. Do u think its possible? Any material u think it is suitable?
I don't know of any manufacturers that would make custom parts for you, but (in theory) you could do it yourself. For the stopper pads, I could imagine cutting and gluing a strip of wool or thick felt and some foam rubber (like "memory foam"), and then trimming them to look the same. For the keys, I could imagine finding a place that could 3D print the keys. For the weights, I could imagine bending thick copper or cold-rolled steel "pencil rod" (cold rolled steel) into the same form. For the circuit boards, you could create a replacement using the Arduino Uno that is extremely flexible -- that said, it would cease to be a "Yamaha" and become an "Awake Monster" keyboard. Good luck and have fun!!
Thanks for your impressive reply David
😂😂lol
I cant imagine i could make the circuit board and bending the metal myself...hahaa
But to be serious, i really plan to make some replacement myself, do u think the thickness of the stopper does matter? I search around the net, but I have no idea how thick i need to make it.
Thanks again.
@@awakemonster9721 np!! The great thing about DIY is that you get to customize it for how **you** like it. The thickness is how Yamaha liked it. For example, if you like the keys to have a lot of travel when you play (i.e. a "deeper action"), then make the pads thinner. If you like a very shallow travel/action in the keys, then make the pads thicker. The main thing is looking at what the wire does when you press the key. Take one, and move it slowly up and down and see how it hits the pads. Notice what happens when you move the wires up and down (just remember its flipped over). As a test, temporarily tape the pads on, flip it over and see how the keyboard plays?? Then, when you're 100%, permanently glue them down.
Great suggestions. Lets me have try soon.
Thanks David.
David i finally finished my work last night. Thanks for your help 😊
