I was not able to get any schematic diagram or any information from GE-Fanuc. There are several money hungry repair services available, but they can go suck someone else's blood. I will NEVER have anything to do with Fanuc in the future, thanks to the way they operate. I still have the bad PCB and will attempt to repair it if I can get some more information. Then I will have a spare. I am wondering where you got the black cube thing from? Did you order from Fanuc or some other place? They told me that they will not sell to me because I am not one of their authorized repair services. This experience opened my eyes to future machine purchases. If I can not get service information with the purchase, I will buy another brand. Thanks to all for your comments!
