keyboard wouldn't turn off, now doesn't turn on anymore
I have a Yamaha p45 digital piano, and sometime in the last month the light kept itself on and wouldn’t turn off, even after pressing and holding the button, with no sound at all. I decided to plug it off and plug it in again. The light turned off finally, but now I can’t get the piano to turn on anymore. Any tips? Do I have to replace a fuse or get another power supply?
