I have a Yamaha PSR-E443 keyboard that won't turned on. If i pressed the power button, the display will flash in second and shuts down. I have tried using another power supply adapter yet the same problem. I also tried using the battery but it still doesn't solve the problem. Please help me. Thank you in advance...
