My keyboard KOMPLETE KONTROL S88 MK1 won't turn on
My keyboard KOMPLETE KONTROL S88 MK1 won't turn on. There is no physical damage, but the device does not turn on, and is not recognized when connected to a computer via USB. Can I find somewhere a schematic of a device to attempt a repair?

Hello,
do you have the power supply conected too?

Good morning,
Oh sure. When turned on - no signs of life.

Can you test the power supply with a voltmeter?

Yes, power is ok. The current consumption when the "on" button is pressed is 50mA.

P/S is probably dead then, often they will show voltage but output no current when they die, or volts drop. Since the MK1 does not power from USB I’d say you need a new P/S

Alas, the power supply has nothing to do with it. I have a laboratory power supply, which actually measures the current consumption of the device.

ok, dead then.

Maybe the power regulator inside near the USB port. I have repaired a S49 MK1 once and checked the power regultaor. The output has to be a bit less than 5 volts.

If I had a schematic, I could diagnose the main board
