Hello.
Has anybody here experienced that their MicroKorg XL has suddenly got a noisy output ("gliding white noise") on power-up, and afterwards a "woolly" sound?
I think I've got a defective output stage, since everything else seems to work fine.
Thanks.
/ Jesper.

Hello,
My MickoKorg XL sometimes doesn´t work correctly - one audio output channel (noise). After disconnect all cables and then connect again work correct. I tried to try with headphones - it was the same. However, one channel is probably wrong. I think so, it´s problem with output stage.. or?

A lot of people seem to have this problem, and at least for me the fix was really easy! Took like 15 minutes!

1 Unplug the thing of course.
2 Remove all the screws off the back panel, they're all the same, and took the back off. No need to unplug the battery wire
3 Then just remove the four silver screws from the board that the headphones jack is soldered onto
4 reseat that board so that it was making nice contact with the metal pieces it screws into
5 then screw it back in, pretty tightly but without forcing it or stripping the screws
6 at this point it's a good idea to put the back on without the screws, plug it in and test it with your headphones.
7 if the sound is back, unplug it and screw the backing back on!

Please respond if this worked for you so that others will have confidence that it's a good fix... maybe I just got lucky....

My Microkorg XL had developed a fault; the right channel was stuck on full volume, while the left could be controlled by the volume knob. This was true for both the outputs and headphones. I tried this fix, and now it’s back to perfect, thank you! Very Happy
