Today I turn on my G70 but it keep silence when I try play arranger or organ or piano. It only play songs and harmonizer. All indication and switchings is working properly (when playing styles it show chords, count bars and blinking LED on buttons -- that is keys is recognizable). But no sound at all -- exept from microphone and songs player.

Mixer settings all OK (I am not change it).

OS vesion 1.06

I tried execute "factory reset" -- no results.

Before I discover this behavior I only send 5MB of brazilian styles to proper directory via USB and successfully execute StyleFinder. But when I try to play with this (and then any) styles and then sipmly piano -- I fail.

What I can do now?
