Members Tony Trout Posted January 5, 2014 Members Share Posted January 5, 2014 Hey, ya'll!! Here's a question for the keyboard enthusiasts out there: For the last long while, I've been getting a buzzing sound from the right speaker on my Yamaha DGX-640 88-key keyboard. Also, the 69-71 notes/keys in the upper register sound really "dead" - like there's not any "life" in the notes when I hit them. What could be going on? I'm new here and don't know how to post a video of what's going on with the keyboard. Thanks for any help that ya'll can give! Link to comment Share on other sites More sharing options...
Members shambler Posted January 5, 2014 Members Share Posted January 5, 2014 Does it buzz constantly even when you aren't playing any notes? Link to comment Share on other sites More sharing options...

I know, your keyboard is broken and is in need of repair....Have you contacted Yamaha technical support and get their opinion? 714-522-9000 Link to comment Share on other sites More sharing options...
Members midinut Posted January 6, 2014 Members Share Posted January 6, 2014 Do you get the same "buzz" when you plug headphones in and use them? Also, do the questionable keys still sound dead through headphones? If so, see the post above mine. If not, you can use the headphone out and plug the unit into another amp/speaker and keep on using it. I had a DGX-500 for 10-12 years. Link to comment Share on other sites More sharing options...
Members Tony Trout Posted July 20, 2015 Author Members Share Posted July 20, 2015 Hey, ya'll! I'm so sorry that I haven't posted since I started the thread here. Been real sick with heart problems and had to have a stent put in my chest way back in March of this year and I'm feeling better - still not my best because of chronic pain and arthritis - but at least I'm still above ground, thankfully. As as far as the issue with my keyboard, it's actually working fine now. I don't know what the problem could have been but I'm glad that it sorted itself out on its own.
