Hi all, I have a dud microkorg XL. Powers up fine, but it only lights up and displays the title screen. It refuses to boot up.

I found a special service mode by chance.
Press and hold *write* *shift*, hold timbre switch to the left and then turn on the power.

This takes it into some kind of test mode.
To navigate you press and hold the ARP button, whilst flicking the transpose switch left or right... press shift to select an item.

I was hoping any of you mkxl owners might give this a whirl so I can figure out what's wrong with mine. I will post my test results here tommorow.

Any idea where I can get a service manual?

So when i go through the menu it gets stuck when i select MIDI THRU and comes up with something like 'loopmd'
It simply freezes when i get to 'key'. Dsp also comes up with a weird message.

All the calibration of knobs and wheels work...

I guess a new mainboard is in order Sad

Hi,

By accident, I just stumbled into this one: the service manual for the XL.

Enjoy
