I am so glad you took the time to publish this video. I own that very same model and started having loose keys (after more than 20 years of good use), so you are my savior here!

[@santodomingo1605]

I use a Technics digital piano (the same model as in the tutorial) for tutees who prefer digital over an acoustic piano. Being 34 years old my model is relatively ancient and occasionally keys fail to sound. I have to dig deeper than in this video to clean contacts with alcohol but your video first gave me the courage to delve into the inner workings of a digital piano. Thank you for an excellent tutorial.

[@ev_lefravi]

You can see videos about Korg SV1 and other Korgs with RH3 keys, this is the same keyboard.

[@chrisstringer375]

Absolutely spot on. My piano is over 20 years old and still going strong, but with a few rattly keys. Extremely clear explanation and video. Thank you.

[@Jimbobalobabob]

Just wanted to say thanks so much for this video. I bought a 2nd hand piano a couple of years ago with one duff key, always meant to fix it but never got round to it. Found this yesterday and within 30 mins it was as good as new.

[@michaelsalais7393]

I'd also like to thank you. I could take mine apart, but not back together. I was shocked that you have the exact same keyboard as myself. So, this was spot on. I didn't think I would find anything out there about this keyboard. I could not for the life of me figure out the springs. Thanks again. Great job. Loved it!

[@TheIanwilding1]

This was a really useful video and fixed my problems with the PX201. I managed to break a key but it still works fine, held in place by the spring. The only foot-note that I would is that the earth doesn't seem to exist on UK models as the earth most likely runs through the moulded plug. The other things I would stress are 1. Unplug first and wait a minute or two as charge can be held in the transformer. 2. Don't force any of the plastic parts. The do come apart easily once you move them in the right direction. If you are applying a lot of pressure, you are doing it wrong. 3. Electric screwdrivers really speed the job up. Thanks for making this video.

[@bigsunflower88]

A first class video with just the information I need to fix my piano. Many thanks, a great service!

[@jeffmarsdensmusic7361]

Carefully explained. Thank you.

[@JonOfFinsbury]

Because of this video, I fixed my problem in minutes. I’m very grateful!

[@EezoTron]

This was really useful when repairing a similar model. The sliding lid on ours had sliced through the wires, and this video helped us get access to where the problem was. Thankyou!

[@rembson]

Very grateful for this video...don't have the exact same technics piano but invaluable stuff for a nervous first time piano dismantler! 👍 Many many thanks.

[@didiergeneste-samissoff5921]

Hello, Thank you for the video : All those clear and sound explanation had helped me to open mine with less fears !!! In my case the issue was a metallic noise when key is released: baize damaged I just placed a new ribbon Cheers

[@Gj57612]

Hey there, same problem just happened with my piano yamaha p45 ... the key D3 plays with some extra metallic noise.. i gave it to the service centre but they can’t solve it.. would you please help and guide?

[@roger40000]

thank you so much just fixed my wifes keyboard all thanks to you! very rewarding.

[@Zippy115]

Worked well for our Technics PX66 - dead key turned out to be a snapped "strike arm" (?) that we were able to repair & re-assemble. Good for another decade. Thx!

[@dewmomma]

This is a great video--I'm terrified I wouldn't get my Technics put back together properly though!

[@ishkaev]

Thank you so much. i just got a used Technics Digital Piano. Some keys were not working properly. So after watching your great video I opened it. Found out that 2 keys were broken. I replaced them with the other keys on the farthest right. I know it is not the best option, but those keys are rarely used. I will eventually order new keys and replaces them. Found an old Canadian coin under another key that was making the metal noise when releasing the key. Thanks again for your video. It has helped so many people.

[@erniebarreto]

Thank you for this video! It’s very helpful and much appreciated.

[@Zilbyfilms]

Thank you! This was exactly what I needed.

[@shericreates]

Thank you. My father repaired organs for a living. I inherited this one and now it won’t turn on. I know there was one key that had a funny sound when you played it. I have to get it going. I don’t know if the grandkids hit something to stop it from playing or what. You gave me some hope.

[@arkestar4551]

Excellent advise and tutorial. Many thanks.

[@buenafe]

Video helped me figure out how to open piano to fix a jammed piano lid

[@juliejenkins5669]

Thank you so much!! This was a lifesaver!

[@ianc214]

Very useful. I had to go beyond this to deal with a liquid spill. I lifted the front of the keyboard and sat it upright on its rear edge. Then I unscrewed a long metal plate and took the switch circuit board off. Then removed the rubber boot where the liquid had spilled. Will clean the contacts and see if it all goes back together ! Shame I cant attach pics.

[@Hacker-yn8dv]

Thank you so much! The issue with my piano (same model), is that some keys make a click sound when they are released (from me playing too loud I would guess). Do you think lubricating the keys as you did in your video would address that problem? Any input would be so appreciated!

[@nanese7493]

Thank you, thank you! Very well done. Oh, BTW, what was the piece you played at the end? Totally my style, but I've not heard it before.

[@PaulLambert2]

Thank you very much! Very helpful for un-jamming a key on a SX-PC 25

[@panoramasatu2327]

thx for your complete information, I need to buy spare part for my piano technis sx-pr600 , where the store to buy?

[@jessiedeemarkgingo6074]

This video is very helpful. May I know what is the name of the plastic parts replaced?

[@TieftoenerS2H]

Wonderful explanation! Sehr gut! Vielen dank!

[@RacinRedPhotography1]

What kind of cleaning solutions do you recommend for a SX-PX73M? I inherited my Mom’s keyboard and it needs a deep cleaning. Even the foot pedals have black spots on the brass. Thanks for your suggestions!

[@Leannmimo23]

May I know what is the white colour spare part call? I m currently facing the same problem that my digital piano no sound when I pressed.. I opened the cover and checked that same as your video! Thank you so much for sharing this useful video!

[@Nico-jp2yy]

Thanks for the video!! I have a question, one key don't react to the sensivity, it sounds louder then the other keys. Mayby you know what i have to look for? Thank you very much and greetings from Nico (netherlands)

[@lorenaromero398]

Hello, have you made a video to repair the Technics piano pedal?

[@garythwaites9030]

Thanks so much for sharing. Really appreciated

[@roksanatarannum1513]

Ive got a Yamaha keyboard probably one of the Psr 500 series. The problem is that I broke off an old converter and half of it is in the keyboard' s Phones/Output port. Pls do a tutorial on how to get it out.

[@georgehollyhead902]

I have a Gear 4 Music DP-7 (I know it's not very similar, sorry) but is there a method like this to fix sharp/flat keys?

[@asimnaveed1877]

Sir what a great help u did by this video.. I don't know whether u will read it or not but I'm having technics SX-PR270 same like in the video so it was not played I think for last ten years so now its not getting on even.. Please help me out..

[@zippelzappel8973]

hey! would you repair my old Korg SP 100? mainly electronic problem though...

[@TheSculptor]

great video. really helpful.

[@PrRout]

Thanks. Can you please explain how to fix a lifted black key. I have Casio privia . My daughter accidentally lifted one black key up. Now there is no sound and it's not even going down.

[@HorLokTing-cs9pu]

I have a SX-PR900, I have not played this for a year or so and I see there's a few keys that when press will have a "hitting a wood panel" kind of sound. Do you know why and how to repair?

[@silentpeasant5600]

Is there any solution ? My only eflat key working but it sometimes sounds waay loud than the other keys. Its so random sometimes working fine but sometimes sounds so loud and it scares me. 😨 And i realized that loud sound becoming more often.

[@greg55666]

I just can't believe it. This is my new favorite youtube video. I have never in my life seen anything explained as clearly and completely as this video. Just amazing. One question: My keys are not loose or stuck, but after we moved, now many of them CLICK whenever I press on them. Do you know what causes this? I assume when I open it I will see, I'm just wondering if you have experienced this. Thank you for this amazing video.

[@KatherineCode]

I have the same problem, clicky keys. Curious if opening it up revealed anything and if you found a solution?

[@greg55666]

+Katherine Code Hi Katherine. The good news is if you open up the piano you CAN fix the clicky keys. The problem is, this video doesn't address the problem at all. The good news is, I'm very proud to say we fixed our clicky keys, and it's so awesome, I can play it now without the constant clicking, I love it and it's totally worth it. But it is way more involved than what he shows here. At no point was anything difficult or were we worried that we would break something, so I say you should try it, but you have to take the keyboard all the way out of the cabinet, so it seems like you're messing with it a lot more. What is causing the clicking is unfortunately simple wear and tear. There is a thick piece of felt along the bottom of the keys. Over time, that felt gets squished down, so it is no longer holding the keys away from the bottom of the frame, so when you release a key, it taps the metal. What we had to do was buy a piece of felt from Michaels, cut it into strips about 1/4" or 1/2" wide, and insert it on the bottom ledge of the keyboard frame where the keys are tapping. To do this, follow all the instructions in the video until you have the keyboard unscrewed and loose in the cabinet. Do not remove any individual keys like in the video, that is not necessary. The difficult thing is that you have to remove the entire keyboard from the cabinet in order to access the underneath. The scary part is you have to disconnect the wires that go from the keyboard to the cabinet (the ones that the guy in the video said he didn't want to mess with). As you can see in the video, all the wires are tied down with giant bread-bag ties. Take a lot of pictures with your phone so you can put things back how they were. (It is actually easy to get everything back together, but it will seem intimidating when you are taking them apart.) After the wires are untied from the frame, then you have to disconnect them from the frame. The only delicate part is unplugging the ribbon wires from the circuit board. This is very tight, so you have to just slowly work it back and forth. It will come loose; don't force it, just work it back and forth. Then there is another small wire that leads to the power switch, and I think one more. When you get the wires all disconnected, then you can lift the keyboard out of the cabinet. Here again, go slow and don't force anything. It comes right out, but it's really heavy, so it will take you a minute to determine how to lift it out. (As I said, this is much more difficult than the repair in the video. It can be done without any trouble, but you have to be brave and careful.) When you and your friend have the keyboard out of the cabinet, put it on a table with one end hanging off the edge. If you get under the keyboard and look up at the bottom of the keys, you'll be able to see where they are clicking. There is a small metal ledge that runs the length of the keyboard. Keep hitting a clicking key and you'll be able to see what I'm talking about. The piece of felt that is supposed to be catching the key has worn down so there's a deep indentation, and it is allowing the metal part of the key to hit against the metal ledge. You need to put a strip of felt along that lip. At Michael's, get a few different kinds, you want it to be as thick as possible without interfering with the keys. (If it's too thick, it prevents the key from coming all the way back up.) We used rubber cement to just lightly anchor the felt to the metal. Then we had the felt cut into about one-foot strips. I got down on the floor and dabbed the cement onto the strip in three or four places, then my friend pushed down all the keys for about an octave at once, and I slid the felt into place. Then she let up on the keys, and that was it! You can bang away at the keys and NO CLICKING! One last thing--you can do the ends of the keyboard this way, but not the middle. For the middle, we placed the keyboard between two chairs, so the middle section was in the air, then I got on the floor underneath it to place the felt for the middle keys. That is it. Then reverse the steps to put the keyboard back. The hardest step is sliding it into the cabinet because it is heavy and the fit is tight. Just be careful. Once you have it back in the cabinet, the rest is easy, reconnecting the wires, tying the wires down, then screw in the screws on the bottom that hold the keyboard in place, then follow the video. The one thing that troubled us was, when we put it back together, it seemed like there was a gap between the cabinet and the control panel. Before you do anything, take a hundred pictures of everything, because I figured out that gap was there before (you always run your finger along it to get out the dust, but there's always some extra in the gap). So everything went together perfectly, and you won't believe you're actually going to be able to play your piano again without the clicking. It is SOOOOOOO great. So, this is involved but you can do it. The clicking on mine got so bad, we made the decision before we opened it that we were ready to get a new piano if this didn't work, but it DID work, and now I have no reason to get a new one. You will be super proud of yourself if you try this. Please let me know if you have any questions! I will be more than happy to help you out however I can. I'm so proud of what I accomplished, I'm happy to spread the knowledge. :) Good luck!

[@KatherineCode]

Thank you so much for the detailed reply, greg! After more sleuthing around online I pretty much came to two conclusions: that the clicking likely IS due to worn-out felt (the piano is over 20 years old!) and that I'll need to take it apart to check for sure and see if there's something else as well. Have been trying to find out where I can get the correct replacement felt before dismantling the instrument, so your tip about Michaels and cement glue is super handy. A friend has already volunteered to help, and after reading your advice, it looks like I'll need to take him up on it, even if he thinks putting grease BETWEEN the keys is a good idea. Hopefully my music will be click-free in the very near future!! Thanks again, your knowledge is of great help! ☺

[@greg55666]

+Katherine Code I hope it works out. One detail--I'm not talking about _replacing_ the worn out felt. Rather what we did is put a new piece of felt in a different place, where the clicking is actually happening. The worn out felt is letting the key go down too far, so it's hitting the metallic ledge. You'll see what I mean if you open it up. (Replacing the worn out felt would be difficult because it's very thick, it would be difficult to find outside of a piano-parts warehouse, I think.)

[@KatherineCode]

Ooh, that's a good detail to know! Thank you! One video I watched showed replacing the felt (on a different make/model), and it took them over half an hour to remove the old felt with an exacto knife and some needle-nose pliers. Your method sounds much better!

[@ICFlore]

Thanks you vert much for this vidéo...i got this model,still working for years until i pull i t for a short distance in m'y appartement,and then thé screen dont light on and it dont work at all.

Hello! Sorry for my English . I'm from Ukraine . I want to replace the grease in the hammer action, I can not even find the name of this lubricant, please tell me what it's called.

[@EiWeiEi]

I used ML MKL1 from the company OSIM Optik www.osimoptik.de . I had no prior experience with the product and informed myself on their website. I figure if the lubricant is good for use in precision optics such as mechanics for objective lenses, it must be OK for the piano.

[@Trasea]

I've had my Technics for 21 years and while playing, a loud boom occurred and there is no more sound. It still turns on, but no sound. I bought external speakers but still there is no sound. I guess it's time for a new one, but not sure what to get... Yamaha, Roland...

[@VidalDuval]

Thanks a lot for your video, I had exactly the same problem! I couldn't find the parts for sale, so instead I had them 3D printed, using the file that someone submitted on www.thingiverse.com/thing:3872069/apps . They were a bit too small compared to the originals (maybe ¼ of a mm, not sure exactly), but they fit with the help of gentle hammer taps. Because they weren't quite wide enough, the keys still wiggle just a little bit but it's a great improvement over that clacking sound they made before. It surely is possible to scale the model in the file to compensate.

[@patricepeyret]

Thank you for an excellent video. I was wondering if there was a way to contact you to ask for some advice. Im interested in building an extended keyboard, one with 108 keys and was hoping someone might be able to help me. I live in Hannover, (können auch Deutsch sprechen), and I have an existing Kawai mp9500 and want to extend either end (bass to go down to the c (extra 9 notes) and up to the b (extra 11). I'm considering to buy another mp9500 for this purpose. there is a contact on my website www.ashleyhribar.com where I can be contacted as well as here. I look forward to hearing form you! Ashley

[@pianokeyjoe]

@ Ashley Hribar Hallo! I am not German but if you bare with me, I may or may not be able to help! I used to have a Kawai MP9500, and MP8 which I sold. I still have the wooden keyboard mechanism for the MP9000/9500 which I had planned on using to build a custom baby grand electronic computer controlled workstation piano. I need to know exactly what it is you are trying to do? There are ways to do it BUT the electronic contact board designs on the Kawai will NOT allow it! It has a key scan IC chip ON the contact board itself as well as an additional circuit ic chip on the motherboard. I do NOT intend on keeping my contact boards for the keybed as I do not need them for my project but this may be of interest to you IF you still want to try to hack your MP9500? I looked at this Technics keys video and say to myself, I am glad I love WOOD KEYS!! Plastic keys suck! Anyway, check pianokeyjoe and find me! I am pianokeyjoe for a good reason!!
