Hello everyone

I'm Christopher from france.
I also have a problem with my yamaha keyboard but with the Arius YDP-141
Same problem as here, no sound but power ok.
Sometime when I touch the cables inside the is some scratch but nothing more.

Can you help me?

 

Service manual here...
There is a mute input to the amplifier, it's worth checking out.
