Hello people,
I have a Yamaha PSR 420 keyboard and is doing a buzz sound when pressing any of the keys. It is happening in the speakers and also when i plug in the headphones.
I have tried with another power supply and also with batteries and still the same.

Please, can someone give me some hints on what this it may be and what to do?
Thank you!
