The NCU in this case is prime suspect since the 5VDC is sourced on this module. If you have another NCU module of the same number (upper left corner, 10:00-11:00 position), try this first. You will have to remove the PCMCIA card prior to swapping. The PCMCIA card in your machine stays with that machine.
