Question about Yamaha Full-Size Keyboard

3 Answers

No sound from Yamaha keyboard

It was fine until one day it cratered for no apparent reason, making only scratchy barely audible sounds and now it is totally silent. I want some one to come here and fix it as I am clueless.
I have it set up to play through a computer. the computer sound works fine and the playback device is activated. should I just toss it out? Help.... thanks,

    your other guy said take it to a repairman. well there are not any in this area who will repair electronic keyboards. so I am stuck with trying to fix it myself and his advice didn't help solve the problem. PS I am unable to pack it up & ship it someplace as its permanently affixed to the stand. thanks.

Since your keyboard works fine with the PC. That means the problem is with the keyboard's Speaker. Either your speaker cable or speaker itself is not working... you have to identify that whether the problem is of speaker wire or speaker.... see that whether the service manual of your gadget is available or not.. if available then purchase the same. It will help you a lot for while repairing
Hope this has helped you....

    I am sorry that you thought I said my keyboard works fine through the computer. NO! I said, the computer is fine; I meant the computer system sound is working and so are the computer's speakers. It is the Keyboard itself that does not work--it is totally silent when its keys are pressed.

    also, the lighted part that shows the function has disappeared. it still lights up, but the function, (i.e. "Grand Piano 100") no longer shows.

    I have bought new batteries for it and will try to replace them myself if I can figure out how to open the battery compartment. it's conveniently placed on the instrument's bottom where I can't see it, according to the manual. Let me know if you have any other ideas, or if anyone is a Yamaha expert, that's who I need. Thanks, Sylvia

    I just had a similar symtom... and I fixed it. Turned out the plug in the wall came loose and the keyboard was being powered by the not so new batteries!

This isn't a solution. I just wanted to say the same just happened to my Yamaha dgx220 after I hooked it to my computer.
I just tried to play a midi file and the speakers broke. It's out of warranty and with today's technology it's usually cheaper to replace than to fix!

The keyboard takes only a specialist to fix the problem. Its also very delicate. The best you can do is to reset it and if the resetting does not work, then you will have to take the keyboard to a repairman to fix it for you.

Firstly, connect a headphone to the keyboard and observe if it will give a good sound. if it gives a good sound, then it means the speaker for your keyboard may have loosed contact or gotten burst.

But if it does not make any sound with the headphone, then it might be a board or sound ic problem. You can also try resetting the resetting the keyboard to default.

Turn off the keyboard, press and hold the last white key and turn the keyboard on while still holding the white key. The keyboard will then restore to its factory default.

If that doesn't solve the problem, you will have to dismantle the keyboard, use a meter to read the panel/board in order to detect the fault and do every necessary replacement. Also, you can do a deep cleaning, by cleaning all the dust in it.

If you can't do any of this, then you will end up taking is to a repairing man to fix the problem for you.

Good luck.

Popped lights on no sound

Probably smoked the output IC(it is the chip mounted to the heat sink attached to the fan) which can be purchased from marshall directly or from one of their service centers. Also P-H216 sold at should work. No soldering required. Look at that IC(chip) to see if it looks burnt or has a crater on it which would indicate that that is indeed you bad component.

Korg Microkorg XL Vocoder Not Working (No Sound)

Check the mic and connections all through its input into the unit. I would check the cartridge of the mic for continuity for the reason that (I think but not 100% sure) on this model, I think there has to be sound at the mic or it does go silent in vocode mode. This is how it digitizes the mic and keys together. The played keys cannot put onto pitch the sound it is NOT picking up at the mic. I think there is a problem with the mic.

There is a scratchy sound when the overdrive is engaged. Its not a hiss but a scratchy sound that is noticeable when you hit a cord or note and its fading out

There likely is a component failure. Possibly an electrolytic capacitor. Also low voltage due to failing power adapter or depleted battery would cause this. Do NOT count on LED for battery health..

My Guitar Amp Started Squeiling And Now It Is Barely Audible.

There is little or no hope that this can be fixed at home, sorry . If it lights up and you have power and still no sound, it may be simi cooked, not to say it couldn't be fixed. But lots of times these days Tecs want as much to repair as a new one. Balanceit out for a new one , to the repair cost . You may just find a new one is the way to go.But never toss out, junk is someones treasure. good luck DFD
