Hi, I have a Fanuc Tape cut with a 6mb control which has been running fine but it has suddenly stopped and the monitor is flickering with no readable display. I have restarted the machine but no luck although the motors power on but I cant jog it etc. I have checked the voltages on the main board which are fine but there are leds lit on the Graph/punch card A16b-1200-0310B which indicates error D6. I have looked through all my manuals and cant find any reference to this so I was hoping someone can point me in the right direction.
Thanks
