Big Trouble! Piano sound muted!

[mactobi]

Hello. I have a CVP 203 and its the 3rd time that piano sound is muted suddenly while I´m playing it.
I turn it off and power it on again and all is OK.

Anybody knows this problem?

Thank you very much,

Fernando.

PD. I hope you understand my English!

I have the same problem, after playing a while , mostly with some reverb, the 203 hangs up, or at least a note keeps playing, until you reboot the piano. that kinda sucks
