Korg DW8000, Mono/Poly, MS-20...

hello all,

i have purchased a third dw-8000 on ebay.
it needed a new battery... i soldered a new one in.
everything seemed to work perfectly fine, except the most important 
thing... it will not play the sounds of the waveforms.

i can turn the noise up and the keys and filters will control the 
sound of the noise. but, i cannot make the two waveform oscillators 
play sound.

any ideas at all?
