S2000 Enhanced Board Issues

[cuda]

I am having a couple of different issues with 2 enhanced s2000 boards. 


First board gives me 2 green lights at the same time and then I get a flashing yellow light when trying to clear chip it.  I am using a 224 and 45 key.  Clears and keys the other boards just fine.


Second board will clear and key chip fine but I get no sound out of it.  I have put a known working board in the machine and it works fine with sound so I know its the board.  I tried swapping the chip board and the sound card and trying it without a sound card, still no sound with any of those options. 


Any other ideas to try or just throw these boards in the trash?
