Well Steve I have completely taken it apart at this point and with everything disconnected (cards and drive) the unit presents the same behavior. All I have is the Power Supply, the internal power board and the CO00 board.

What would be a good next step? Replacing the internal power board? Could the issue be the CO00 card?

Thanks,

Christopher
