I just bought a yahama psr ew400 serieskeyboard yesterday. The seller delivered it to me himself but because it was late in the night, we couldn't test it before he left. I brought it home and that same night connected the adapter and turned it on. It only lasts for barely 5 seconds then it goes off again. Have turned the 'auto power off command' too off yet it keeps going off after I have turned it on. Please help me out. I'm stuck. Is it adapter problem, keyboard problem or what else may the problem be? Fresh Yamaha psr ew400 keyboard series. Please help me out. Thank you.
