My WK-1200 which I use with rechargable Nicad (my pin in the AC/DC plug broke a year ago) Has been working great.
But a couple of nights ago I turned it over to change the batteries. When I returned it to its position on it's keyboard stand the demo would play and the LCD was working fine but I got no sound when I play the keys.
I can change all sttings on the LCD and both demos play perfect even showing the keys hit excetera, but when I play the keys in normal tone mode nothing.
I'm missing the troubleshooting page from my manual and I just wondered if maybe something got pressed or if there is a hidden reset button or what I can do short of taking it in to an expaensive technision or if maybe any of you have had this happen to you. I have a feeling it is something extremely simple but it is evading me totally.

I need you help!!!!!

Thanks in Advance
