You probably need to clean the contacts underneath those keys that are not sounding, otherwise check the components (diodes, resistors, etc..?) that are connected to those contacts , also check the wires and/or the connector that goes from the contact plate to the main board, see if there are broken wires and resolder, check if the connector pins are dirty or badly soldered and clean/resolder if necessary.

if all of the above fails then It is not a bad thing to check other connectors too, also any ICs that are plugged into sockets as there may be some oxydation so cleaning the connectors and unplugging and reinstalling the ICs could help somewhat.

Hope you can fix it.

It is likely the key contacts are dirty. These are usually conductive rubber and both the rubber pills and the circuit traces they contact should be cleaned with 99% isoprophyl alcohol. This invoves dis-assembly of the keyboard.

The worst case is if the keys sustained a hard hit and the circuit board underneath is cracked. That is fatal and requires a new circuit board.

QS8 keyboard. Why is volume in organ mode much louder than piano mode when I switch between modes without touching volume slide?


On organ mode, in general, almost all brands of the modern keyboard, velocity setting is not enabled. Setting velocity is used to determine how much the level of the sound that follows how strongly you press the keys. It is really just to imitate the sound of vintage organs, which in the past, electronic organ technologi not use the velocity on the keys. So, how strong / slow we press the keys, the sound level will remain the same.
At the Piano mode,modern keyboard using setting velocity. This also to imitate an acoustic piano, which, if we press the keys slowly, the sound level will be slow as well, and vice versa.
So, in your case,at the same volume slider, try to play on the organ modes, note level. Moving to the piano mode and press the keys securely powered (full power). Then the sound level should be equal to the organ mode.
On modern keyboards, also included organ sound that added velocity setting. Usually found on the user bank.

I have three keys getting malfunctioned /cords not changing in left side, on split board.can this be fixed?


If those keys work normally, it's hard to see how the key switches themselves can be bad.
Is your keyboard MIDI capable? If you play the same chords, does the MIDI output look OK?
Could it be that your keyboard simply can't play all of the different sounds at the same time? I know some are limited in how many simultaneous tones can be played.

I can hear only one side of the sound coming out from Korg triton extream keyboard. It's not the cable problem for sure. i tested both the earphone out put and the Left and right out put. Did a


So you're saying with headphones you also only hear one side? I would suspect the internal amp is panned all to one side. There are also several other settings in this unit where pan can be set so you may have to check several areas. If you don't have any specific custom settings made I would try a restore to factory defaults. If that doesn't resolve it you likely have a hardware failure which is likely not repairable. I strongly suspect a panning issue though.

Hello everyone, you are my last hope. Here is my story I have a Triton Le bought in Mexico in 2005, it has the American AC/AC power supply cable. I moved to Europe and there I bought a 240V INPUT (9V...


I have been trying to find a schematic, however the damage should be limited in the unit.

Since there is only 9VAC input, we know that it has to go through a rectifier and a filter capacitor and then likely a regulator. I doubt the problem goes beyond the regulator.

The screen light MAY be independent of the logic power in the unit, the LED's will NOT be independent.

The voltage rating of the fuse is NOT a problem.

You likely blew out the rectifiers as a start. They may be individual diodes or a small module with four diodes inside.

The diodes SHOULD have survived but check them with an ohmmeter on the diode range. The Filter cap may be destroyed, and alsothe regulator which is likely a three terminal one like a 7805.

If this is happening on all keys it sounds like your aftertouch is not set right. You may not have gotten the key assembly lined up quite right also. Check these first.

A ''static'' sound coming from ALL outputs of Korg Triton


try cleaning ALL the contacts involved with Caig DeOxit (D5, S5. F6, G5, etc.) products*, they work very well. e.g.; cables, inputs, outputs, and (if you're confident) all the contact points "under the hood". this static you speak of sounds like less than stellar contact points and can addressed at home if you've the motivation to DIY.
