My MicroKorg Synthesizer works fine with batteries, but won't work with a 9V DC adapter. If I take the batteries out and just plug it in and turn the power on, it does nothing.

wrong plug

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.

Sound still audible when volume is all the way off and output volume only even between channels when knob is in the center position

Hello.
I have a similar problem, I guess.
Do you have a "rusty" or fluffy sond out, too?

Hello everyone. The dial on my microkorgXL which changes the operations of the knobs does not work, is it possible to fix this? Without it I can't change anything or use the on-screen editor. I haven't...

Sounds like a bad rotary encoder (the part that the "dial" is attached to"). If the circuit board or solder is not cracked in that area then that is likely the problem. You could find the part at mouser.com (about $1) and would need desolder the bad encoder and solder the new one in place or get the whole PCBA(printed circuit board assembly) from Korg.

I have a Korg Microkorg XL. The volume control is not fully functioning. It won't get really quiet or really loud.

The volume control must be have dirt in it. When you move it do you hear rustling noise. A quick spray of WD40 spray into the control will solve the problem.

Our church has a Korg M50-88 synthesizer. The sustain quit working and we have tried 7 different pedals. Any suggestions?

It may not be the pedals as the fault can be oriented within the set.
So I think you can open the back of the set and check for all connections to be tight , remove and refit.
If this wont solve it is not adviseable to check this higly intergrated PCB without a help. So consult the Korg service.

Microkorg not turning on

I can tell you what it is from first-hand experience. The audio in LED's coming on and going out means that a power supply putting out more than 9 volts DC was used...or the wrong polarity. Korg sells a repair manual for about $12 but they ultimately need a whole new circuit board. If the wrong polarity supply was used, then maybe only a diode was damaged. This would be a cheap fix. But more than likely it knocked out one of the large surface mount IC's that us techs don't even dare to replace. Korg charges around $280 for a new circuit board. A used working microKorg sells for this much.

Honestly, I would stay away from Korg products and many others. Many companies are now using surface mount components which are cheaper and harder to fix. Moog synths are expensive but they are completely fixable(and are built to last). If Korg would install a $0.25 voltage regulator on the input of the DC jacks, the unit would be saved. I think this pretty much sums up the build quality. This is probably not what you wanted to hear but is how it is unfortunately.

A diode or two could need replaced. I can't find a schematic. A microkorg would not be a fun project to take on yourself. Check this page and put your zip code in and check for a repair center (if you are in the US..I don't know if there is a repair center in Japan.

Hi Mate, If you still need the information its korg part number is; 510324023008, and manufactures part is S-8520F30MC, costs £2.50, and £5 P+P. Hope this helps, this is in regards to IC5 on the Korg MicroKorg Keyboard.

Where to find this, and or, do you have any of these extra lying around? Because everywhere I found has a minimum order of like 3000 at a cost of .49 US ea.

The above is wrong the actual part number from the korg MicroKorg Service manual (which can be found online in pdf format) is S-8520F33MC

I have the same problem, I changed the IC5 with the one in Anthony's link and it still doesn't work. Do you have any idea about what else could be broken?
