Yamaha DTXpress/DTXplorer/DTXtreme

All -

I just bought a used DTExpress, looks to be in amazing new condition, but
can't get the pads to make any sounds!  The other stuff seems to work, but
the pads are silent.  so far, I've:

1) Hooked up all the cords and turned on the brain
2) Gotten the songs to play, the click, etc. thru the headphones
3) When I hit the tom2 and tom3, it actually ends up changing the drumkit on
the brain (but doesn't make any sound)!!
4) but when I activate the Groove, it *does* register each of the drums, BUT
it just doesn't play any sound, it's silent!!

Any ideas?  Has anyone had a problem like this before???  I actually didn't
get a manual with the purchase, so everything's a little blind... =)  Anyone
know what the display is supposed to say when you're playing?  Does it say
"Yamaha DTXpress" or "KIT=44"etcetc?, where the 44 is blinking?

Any help is greatly greatly appreciated.  I'm stoked to get this working!!!

thanks/regards,
Hansel Lynn
