Robot abb

abb robot presents this error "connecting to the robot controller" I have already checked the cabinet and the only thing I could see is that when the robot is turned off the computer turns off immediately and I think it is not copying the image, it may have something to do with it ? excuse my english i had to translate

Well, I don't have a way to try another flexpendant, but we checked the cable and it's fine, it's not damaged. When it started with this problem we solved it by turning it off for a few seconds and then we turned it on again and it worked, but as time went by it no longer wanted to work.
