I have a problem with a RJ2 robot controller. The teach pendant is continually freezing however is ok if the robot power is cycled. The only fault indication i have is via the LED indication on the CPU. This points to bad parity on the RAM. I am reluctant to change the CPU though due to not having a very recent back-up. Can anyone offer any advice
 
I had the same problem with a RJ3 controller. I finally had to send the CPU out to be repaired.
