I just got a soul caliber 2 systen 246 and when I turn it on it get a screen that says JV Master (2.11) Not Connect

I/o 1 No Connect
I/o 2 No Connect

I have a system 246 jamma IO connected, do you think its bad?

Ive flipped the data cable over and tried that with no luck. There is a LED lit under the test "warning" also?
I ve adjusted the power al over the place to see if the LED would go away but it doesnt, it either flashes at low voltage or stays lit on higher voltages.
 
If no one here can help, try Subbie, Defor or Suparsaru over at the Neo geo forum. Those guys are experts with this hardware.

I've had the JVS warning before but I can't remember how I fixed it - it wasn't major. It could be that the data cable is just bad so it's worth a shot changing it out completely. Do you have a spare? - a Midway sound board cable (MK1 or NBA) is identical. Not sure about the test warning though, that could be the Jamma B board acting up.
