If it has a ZDI, NTP, and ZCK logic board then it is a BOSS 6.
I would start by checking all the logic voltages and fuses. Values and test locations are in the maintenance manual.
I have seen too often a 70007 on the display. This usually meant that the LSI (mother board) was not functioning.
If all voltages are correct. I would pull each logic board one at a time and clean the edge connector with a soft eraser and reinstall. This works very often in bringing a machine back to life.
