I have an Okamato EDM machine that is using a ISE Electronics Corp. board for its digital display. It is a model # CU20029SCPB-T. There are also these numbers on it. PW287-101,20A,6C25L,181-M2V0. I would like to know if this board is available or repairable. For some reason this board locks up the display. I can power it down and usually it will come back up.
