VIB didn't work. I replaced the following harnesses.OP panel>VIB, VIB>controller frame connector, controller frame connector >IPU. No luck. I replaced the BCU, CNB and I/O PCB, no luck. Checked input voltage from PSU to controller PSU, good. Output voltages from controller PCB, all good.
I have implemented most suggestions from CTN, all suggestions from the manual and all suggestions from the goose guide.
Each board or component I removed from my working parts machine and installed on the problem machine I reinstalled on my parts machine, and it is still working fine.
If anyone has any other suggestions, throw me a bone. I am out of ideas at the moment.
