Hello,
I am a new poster and a long time visitor. I have multiple Fanuc Rj3ib systems and my most recent acquisition is a used unit that has some problems. When powering up the system, I do not get control panel activation or teach pendent response. The controller seems to power up normally with fans and normal LED indicator lights on the back plane. The I/O modules do not seem to have power either. I would appreciate help troubleshooting this problem. Thanks in advance.
