Well it actually was voltage problem with the ac adapter, i luckily have one that i bought years ago because i moved to europe and needed one of 220 v (also korg original) so i tried it using a voltage converter (110-220v) and the ms turned right on without any problem!
Thanks for the fast response!

Try the factory reset, and diagnostics test.
If it doesn't help, then it's hardware problem - check voltages inside, cold joints on PCB, reseat IC's in sockets, connectors...
Well all of a sudden my Ms2000 stopped working, everytime i turn it on it just light up the number buttons in random order and with very weird sequences of lightning. (like 1 and 4 and then 7 thru 16)
The lcd screen does not even light and the rest of the buttons and leds just flash at the beginning and then turn right off.
Sometimes it doesn't even start at all, like it has no power.
I use the original ac adapter.
Also i own it for about 5 years but i bought it use.
