keys on the keyboard stop working
Hello some of the keys on my keyboard stop sounding. Does it means i´ve got a broken key? I am sure the keyboard hasn´t been hitted by no means.
If those keys which do not produce a sound are somehow hanging (are lower than the other keys) and are somehow slack, the problem is related to broken keys. They need to be replaced. In this case, you can use this guide here on ifixit.
Just keep us posted what you figure out.
My yamaha dgx 230 had the same problem too, except, if I pressed it lightly, it sounded as if I were pounding on it. And the bad thing is, it happened to 14 notes, which were the same G#'s and the same D's. But if I press on it normally, it doesn't make a sound. Do u think it has something to do with dust or the rubber pads?
I'm a Yamaha engineer at Keyboard Repair Centre in Wirral.
I have had this fault in the past. It may be the volume control which has gone high in value. If you need the part number then let's know. Its not a difficult job but you need desoldering and soldering skills.
The problem isn't usually the board.. its the rubber contact that either need replacing or cleaning. Clean with pure alcohol.. I use Isopropyl alcohol and a lint free pad like chamois. Don't use cotton bids.
If the fault is on the first octave the part number for the contact is V3413800
Top Octave? V3413700
All the other octaves: V4313600
If it is the board its in two halves... lower half. Pt number is V3414200 and the top half is V3414300
Contact Yamaha in your country and ask for spares dept, In UK the number is 01908366700 You can pay by card.

Can you use spirit to clean the rubber contact or the circuit board....I also use Yamaha psr e423 and some keys seized to sound and I realized the problem is from either the rubber or the circuit board.. I need help please.
I have yamaha psr i455, from yesterday its D# and A key of every octive was not working. I am trying many ideas which givesn on internet. I have a hair dryer i use on my keyboard and now my keyboard is working properly. I think its lhappend because of moisture due to rain… i purchased Silica Gel packet and kept near to keyboard then after no such problem happened.
I have Yamaha ypg 635 and there is a section of keys c thru b and the black keys as well that dont work. I assume this comes in sections so it may be a bad section of keys?
Hey. I hv Yamaha EW410 it's ln good condition (8 months) so when I play Ab on low note it also add D (D +Ab) ,when I play G it also ad Db (Db+G) , When I play A it also add Eb (Eb+A) , When I play Bb it also add E(E+Bb) , When I play B it also add F(F+B) n When I play C note it also add Gb note(Gb+C) . In short when I run chromatic (bass side) it only play G, Ab, A, Bb, B & C while Db, D, Eb, E, F & Gb fails to play…
I just had this problem where my E and Bb keys had stopped working entirely.
I used a firm slap directly to the right of the logo above the keys to jostle things back into place.
Works so far, will update if anything changes.
I have a Yamaha DGX-220 and the volume output is very low. Can I fix that, or must I refer ta specialist?
