open up the machine and make sure the cable is connected correctly
now if you have no audio at all then you need and oscilloscope to check the digital data from the echip for the output channels for the dacsalso check that the keyboard is connected correctly

Ok, I added Grand Piano bank to OS disk... System is loading correctly, bank too. Ive got about 30 presets to choose but when im loading any there is no sound. I checked special menu for disabled channels and there is no disabled ones. I recalibrate volume slider so im sure lowest value is the lowest and highest is the highest. Im checking my outputs with Audiotechnica headphones ATH-M40fs through all outputs and nothing. Keyboard sending midi notes as well. When im loading sequences from that Grand Piano bank and pressing play there is no sound. When im plugging 1/4 TRS Connector of headphones to the outputs i hear characteristic sound crackles (like in other vintage audio gear). What can i say more... floppy drive is not original one.
Thank you very much Jammie for your advices.
