I own a Kawai sx240. Battery leakage ruined it. I made it repaired, and working. I put it aside three months without using it. Today I took it out its suitcase.
I turned it on, all was OK except... I get no sound, both from phones out and from right or left out (no signal out).
The switch beside Signal Out block is in +4dbm position.
Everything is working! I was able to load again factory presets without problem. Every switch is working, only no sound.
The strange thing is that if I put the volume at the maximum (both volume and lower volume), I hear the sound I'm playing, but it's very very low in volume; it's like it was muted for a reason I don't know.
Can someone help me? Maybe a reset can solve the problem?
Thanks a lot.
Have a nice day
