When I started my lathe today with a Fanuc 3TC control it started as normal but shortly after the axis took off and the CRT went blank. I shut down and started back up the same thing happened again. After a few times of this now the CRT does not come up so I don't know what is going on. I can't get the machine to do anything. I was wondering what would happen if the memory batteries went dead between uses? Anyone have any ideas for me. Thank you for your time and hope to hear from someone soon.
