without parameters it's not going to do anything anyway, regardless of even if it is 100% working.
its a pretty old machine so I would guess if there are no alarms and nothing on the screen then the CPU isn't running and you
have a board problem..... although it can easily be a power supply problem (several voltages are required for proper operation)
what Fanuc System is it? I'm guessing 6T, 5T or 3T?
