We have Fanuc RJ-2 Controller that is stuck on boot. I have 4 green lights and the middle red light on the CPU. Just replaced the CPU after a checksum error. The PSU has also been replaced recently. I haven't done work for this company for a little over a year and last time I was there this robot was functioning. They had only replaced the PSU. I replaced the CPU. The Teach pendent Shows the boot screen showing the test are all ok and the teach pendent is ready. All of the lights are on and it won't move from this screen. Can't find anything asides from possibly the PCB could be bad. Any suggestions would be very appreciated.

You did reload the software ?

It does not necessarily have to be the software, the problem that I found lately was some components in the CPU that are responsible for the communication between the teach pendant and the CPU, it can be your cable or even the teach pendant itself.
