I fix a loud key on my Yamaha DGX-520 digital piano. Thrilled!! 

I was very happy to read your comment. In these times we frequently have to try to fix things ourselves and it is very satisfying when we succeed! You brought your instrument back to life and will put it to good service!! Rich😊😊

Sometimes you take a leap of faith and do the process and wow! it works. I'm glad you got to experience the same thrill I did a few years ago when I made this video. I'll never forget that day. Rich 😊

I have 3 that are doing that

@@richdavis4007 Sorry, It does NOT have sound after G9 nor below C-1.

How about that! Super! Glad my video helped! Rich

😇

Thanks. I was thrilled to discover this solution and the fact it worked put a huge smile on my face. Rich

Super! You hung with it and didn't give up! It's a great achievement! Rich

This is one of the most special videos I have on RU-vid, and there are thousands. Best wishes with your fix! Rich

You comment makes me happy today. I know what a big deal it was for me to fix my keyboard. Very best wishes to you. Rich😊😊

I found the fix on RU-vid and then tried it myself. I was thrilled to be able to fix my keyboard with no experience with this sort of repair. 😊😊

I'm glad you found my video and hope it inspires and helps you. I've posted 6,000 videos on RU-vid and this could be the best one. 😊😊

Super! Good tip. Rich😊😊

Glad it helped!

Thanks, Frank. This video was made several years ago during a whole different life it seems. But I remember the day and the excitement so clearly. This was a big achievement for me in what took a couple or three hours . . . including making the video! Best wishes to you. Rich

It showed while searching on how to fix some mute keys @@richdavis4007 and I stayed at the end of it! My problem is that I don't have louder keys, all the contrary. I already started collecting what I'm going to be using this long weekend to have it ready. At this point I even found the expression pedal and the sustain pedal, which by itself I'm calling it a good omen. Hope you are doing well in health and surrounded by your loved ones. Have a great rest of the year.

@@FrankBruce It's nice having a little extra no-rush time to do something like this. I've got a Mavic Mini drone I need to give some attention to. You've inspired me to tackle my project! Thanks, Frank. Rich

This is completely new to me! You are the first person who has had such luck that I know of. Thanks for letting me (and others who read comments) know about your success. Rich

@@richdavis4007 You are very welcome. The service guy even added a sticker beside the serial number to indicate, that this piano now has the official fix. My parents have a newer CLP than me, I do not think they have the problem. Indicating that this pertains to certain models and certain production years (I forgot to ask that :-)

@@druffyw Sounds like this pertains to just a few Yamaha keyboards. Thanks for all your information. I'm sure you are happy with such service and result! Rich

That's the spirit! I wish you the very best. The day I fixed my keyboard and made this video is one I will never forget! It does help that viewer comments help remind me, too. Rich Davis

Thanks for your tip! I've done my fix and hopefully will never have to do again!! Your suggestions may help others. Rich😊😊

Thanks for the tip!

Thank you so much!😊😊😊

I'm glad if my video helped. Thanks!

Thanks for your helpful information!!😊

Thanks! Rich

I'm glad my video helped! Rich

Good luck!

Thank you! 😃

@@richdavis4007. You're welcome. At video 12:06 I saw a cat. Very wonderful. 😘❤️💯👏

Sinto muito. Obrigado por me avisar!

I would think, yes. 😊

Those are slippery little things, for sure!

@@richdavis4007 Yeah haha, ty for the video! it helped me tons :)

@@Lermacto I'm so happy my video helped. It was a great day for me when I fixed my keyboard and made the video, and it always pleases me when someone else can use what I learned. Best wishes to you! Rich

I saw it. Evidence was very clear. Thanks, David. Rich

Thanks for the tip! 😊😊😊😊😊

Maybe it's humidity that caused your problem. There was obviously dust inside my piano and dirt. The people who had it before me did not take good care of it. All I can recommend to you is contact Yamaha support. I wish you the best. Rich

@@richdavis4007 thx..yes i always lived near sea..though moved to dry climate now..to top it i have a labrador at home..last time i got it serviced by Yamaha to discover it was because of dog's hair🙂 Will contact yamaha again..most of the centres are shut due to covid. Delhi is presently facing covid music😥😢

Good luck, friend. If you have one of these digital pianos, I guess you could take it apart and have a look. If you can keep track of the screws and have long screw drivers it shouldn't be too hard. I did the job and made a video as I went in 2 or 3 hours. Rich

Yes rich..it's digital and wil try out the repairs

Good luck. You'll be happy if it works and you don't lose much, but some time, if it doesn't.

If you can clean the uke using a blower, by all means go for it! The main thing is to get your keyboard back in service!

I'm sorry I don't know the answer to your question. I fixed my piano by watching RU-vid videos and then trying what I thought might work to fix my specific problem. That's the best suggestion I have for you. Good luck! Rich Davis

No. Touch sensitive.

I don't know. I'm not an authority on that topic. Thanks. Rich Davis

I'm glad if my video helped. Thanks! Rich

It should work the same way. 😊

It's possible cleaning could solve the problem. If you suspect your piano has been in dusty conditions, it might be worth a try.

@@richdavis4007 i tried cleaning with alcohol and water and it didnt work, do you have any other suggestion that i could try sir?

@@hr8253 I don't. I hope you find a solution somewhere. Rich

@@richdavis4007 Thanks sir, appreciate the support

It could be the normal sound the keyboard makes. It's like turning on a radio and you hear something before you find a channel. I'm not a technician and can't provide much help on this.

I only know what I put in the video. I don't have this keyboard anymore.

Try melting some solder on it and file it flat.

“Works like a miracle. I used a 8B pencil. On the carbon pads. For the keys which were still not working, use a dust free eraser, blow clean, then apply the pencil again…all worked well. Piano I own is a Kong SP 170S” -Zany This is what another wrote on a similar video as this. That “black thing” you mentioned is called, a carbon pad. Take care!

The only solution I know is covered in this video.

I won't argue. 😊😊😊

Yamaha.

Good luck. I hope the video works for you.

Thanks, Jody. I appreciate you reminding me about this video that needed to be put back up on RU-vid. Rich

I hope you can fix. Good luck, friend.

Most likely a bad DIODE. This method would not work if all the same keys are out.

Thanks for your comment.

Your comment made my day. I'm very pleased my video helped you get back to using and enjoying your keyboard. Thanks for taking the time to tell your story! Rich Davis😊😊😊😊😊😊😊😊

I have a yamaha E363, it has been with me for almost 5 years or so, it's in pretty good condition but I have the same problem, I thought it was dust, but it's two specific keys in all octaves; D's and G sharps. They are too loud if I play them on normal pressure and If I use a lot of pressure they either go silent or play 3 to 4 times. I tried this a lot of times, even used alcohol pads which made it better, but still loud, but it isn't working and I feel helpless, I can't afford getting it fixed from the store either, and I think something's wrong with the motherboard. I haven't played it in months, it was the only way I could relax and ever since then, I haven't been feeling amazing. I get what you're saying, that your eyes were tearing up as you wrote, and so I wanted to say that you're not being dramatic at all, I feel what you felt for those 8 months, I hope you're doing great and so are your piano skills. I'm thinking of maybe selling it and buying a new one, or maybe just stop playing piano since I can't really watch it sit there and feel helpless

​​​@@AjwaQurIf you are having issues with keys in the same octave across the entire key board, I think I know what is causing that. The CPU inside the keyboard can only process one key at a time but it does all of them so fast over and over again you can't notice it. Yamaha keyboards don't scan from the lowest key first to the highest key last (progressive), they instead scan (interlaced) by scanning all the Cs first, then all the C#s, and finally all the Bs. They do this to save micro chips and for a less noticeable scan delay and is called multiplexing. When a problem is common to the same key in each octave, its the Common Note drive line that is flaky. I am familiar with Yamaha keyboards (I have a DX7). I could probably fix it but it would not be practical to ship. I suggest you find some big engineering companies in your area and ask if you can post a flyer on their cafeteria bulletin board that you need help. If you go to several companies you may find a hardware engineer that might fix it free (except for the cost of parts). I do this often but only for local people.

I'm glad my video gives you hope. I remember the magical day a few years ago when I fixed my digital piano and made this video. It was very exciting. Rich

Sounds good to me. Rich

I'm glad you were able to fix most of the problems you had with your keyboard. You're right in that we probably can't keep fixing them forever. The money I save in piano tunings might buy a new digital piano every few years. I love my Yamaha DGX-650 white digital piano. I've had it maybe five or six years now and have had zero problems. I would never want a real piano of any kind as I grew up musically with Yamaha digital pianos. I couldn't live without all the voices and the multitude ways to play. Thanks. Rich

@@richdavis4007 also may I add there is a lot of rubbish on youtube these days but your video has helped me a lot as long with others to eliminate some of the guessing I would have done if I tried to fix my digital piano without this so thanks again for the post

Super, super, super! Way to go, friend! Rich

I'm very glad my video helped!!! Rich Davis

Thanks for your helpful information!!

Thanks for your helpful information!!

Good luck!😊😊

I'm glad it worked for you! Rich 😊😊😊

Yes, I'm sure.

I can think of no other cause.

Super!

It was a very exciting time. DIY is the only way to go!

Good luck. I hope this works for you as well as it did for me. Rich Davis

Thanks for your helpful tips! These should be useful for people watching my video! Rich

@@richdavis4007 Rich, it is refreshing to see people give it a go like you did. It's my pleasure to add my 2, 3, 4, 5 cents [smile].

😊😊😊😊😊

This is one of my most popular videos out of thousands I have posted on RU-vid. Thanks for noticing! Rich

Probably best to completely ignore that! That's my opinion after years of owning and playing these keyboards. I'm not a piano or electric keyboard repair person.

Thank you! Nice tips for others who want to clean and fix their keyboards! Rich 😊

This is my video. I'm the person who made the repair. Thanks. Rich Davis

Yes, that would be a better choice. Thanks for the tip. Rich

@@richdavis4007 I have one key and will be doing the same today. I have a sour note on one key in the 7th octave. These are fun to work on. I had to find a bad note on a 550 a while back and it turned out to be a cracked trace. I located the crack location by troubleshooting the symptoms and found a single point where this could happen. Opened the unit and verified it was where I thought.

@@ipscone You've got the right attitude and exerience. No point in fretting over the job. If it's fixable, I'm sure you'll succeed. Best wishes. Rich😊

Super!

I'm glad my video helped and hope you enjoy piano once again after all these years. I started music late but really enjoy piano, ukulele and singing these days. I try to post a playing and singing video every day, which keeps me motivated. Rich

Your problem is beyond my area of expertise. My only advise is buy a new digital keyboard. Very best wishes. Rich

Thanks for reaching out. Really appreciate your help. Regards, Nette

Thank you! 😊😊@@nynettecomfy4275

I'm glad my video helped!!!

Super!!! 😊😊

Thanks for sharing your experience. For those not wanting to take their keyboards apart, your methods sounds worthy of a try. I can only vouch for sure what I did in this video. Very best wishes. Rich Davis

Lamento que você tenha um problema com seu novo teclado. Se você sabe que há um problema com ele, eu o devolveria, não importa o inconveniente. Ou entre em contato com o vendedor e peça que resolva o problema.

@@richdavis4007 obrigado pela resposta. Eles me enviarão outro do mesmo modelo.

Isto é excelente

😊😊😊😊 thanks for watching!

Best wishes to you! Good luck, friend. 😊😊😊

@@richdavis4007 Thanks alot. I managed to fix it. No loud keys and the keys that weren't sounding are now sounding

Super! Super! I've very happy this worked for you! Rich Davis@@bashiiesibuyi6770

I'm not a piano tech. All I know is in this video. I hope you find a fix. Rich

😊😊😊😊😊😊

Good luck. It worked like a miracle for me. Rich Davis😊😊

I hope it works for you as it did me. Best wishes. Rich

I'm glad my video helped. Thanks for letting me know! Rich

I hope, hope, hope it works for you. If so, you will feel wonderful!! Rich

😊

I hope it does! Rich

It worked, i thank you with all my heart man

@@tasty_tunes Wow. Fast work!

😊😊😊😊

It's really frustrating to deal with online support sometimes. That's one reason I was so happy to fix my keyboard with help from RU-vid videos. I hope you find your solution. Rich

If it's new and can be returned I would. If you are willing to play it as is, I doubt if there would be any harm. On my Yamaha synthesizer I have a key that's just a bit spongy. Doesn't quite feel like the other keys. I play on. 😊😊

@@richdavis4007 when I play the spring sound doesn't brother. . Do you have a montage? ☺

Very best wishes to you. Rich Davis😊😊

I can prove no more help than this video. I'm not a piano technician. I solved this problem for myself but I have nothing more. Best wishes. Rich Davis

Yes, it was!😊😊

I can't help, I'm afraid. I haven't had this keyboard for years. Rich Davis

@@richdavis4007 ok np ty for the reply and happy marriage anniversary, live long stay healthy 🎉🎉

That's a pain!

Hahaha a pain indeed,but thanks for the video was really helpful 🤗

😊😊

I'm thrilled my video helped!😊😊😊😊

Thanks for the tips. Rich😊😊

I wonder if you can reset the keyboard. Check your manual to see how to do that. It might be that unplugging and resuming a fresh start might help. Sounds like you may have unintentionally set up your keyboard for the strange actions it's taking.

Thanks for your suggestion to others! 😊😊

Good luck. Best wishes. Rich 😊

That would have been very useful!! I'll remember next time I have a lot of screws to deal with in a project. Thanks!!! Rich

@@richdavis4007 I learned that egg carton trick from my dad working on engines. I am 60 now, so I pass on these tid bits when I can.

😊😊

😊😊

I've had my DGX-650 about seven years, play it every day, and I've had no problems with it at all. It's hard to imagine your piano having the same problem I had. The keyboard I cleaned was purchased at a thrift store and probably not taken good care of. I wouldn't think a piano would have this problem after one month.

Thanks for responding to my video. This was my first and last attempt at a repair like this and I'm very happy it was successful regardless of mistakes that may have been made. Your commentary may help others do a better job while obtaining a similar result. Very best wishes to you. Rich Davis

@@richdavis4007 Yes, it's a difficult job. Some are more tricky than others. Glad you got it going. It's just a shame that this problem occurs every 2 or 3 years as its annoying. One thing I forgot to mention. Contact cleaner is good for cleaning the board. Best wishes to you Sir.👍
