I didn't try the board before dis-assembly. I
purchased the IPX, then
the keyboard, then got a monitor (that apparently won't work with the
cgsix).
I've never seen one of these keyboards, but I'm assuming that there's an
encoder board with a microcontroller (and maybe some other stuff) and a
board of keyswitches, possibly with diodes.
Again I'll assume it's a matrix-type keyboard (no other design would make
sense). It should be farily easy to identify the row and column lines on
the connections to the switch PCB. And then you could see if there are
any obvious shorts in the matrix.

It sounds like if you can't find a stuck key
(maybe) or some other
problem, then you may have to go and
get another keyboard. they are'nt so expensive as to preclude this.
I'm wondering if maybe the green board with all the contacts has a bad
component. I was hoping I had re-assembled something wrong and was
grounding something out.
