Most probably the external power supply adapter is broken and has to be replaced. Can be easily tested with a multimeter.
You do not necessarily need to buy an original Yamaha adapter, Almost any aftermarket switching power supply adapter is suitable having the same output voltage (V), same or higher max current (A), same polarity and same connector size.
