I have it for 2 years now. everything worked cool. Today i powered it on and nothing. No sound, preset buttons have no effect, LEDs on left section [vco] are switchable. all diodes except presets are lit. what can be wrong? service manual is not helpful here

maybe a multi-pin connector came loose?

I've fixed a couple of synths that way, usually doesn't hurt to open it up, look around, see if anything is loose or burnt or ...?

i already opened it. connectors seem to be ok - i replugged all of them, fuses ok, voltages also are correct

Have you checked the battery? Notorious battery leaking monsters I'm afraid. And the battery is strategically placed near the memory and CPU...
