Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Either you have a cable to/from the control console that is loose or defective or broken... or the console itself might be defective.
So the right thing to do is, to check the connections of the cables to and from the console, and re-seat all of them, at both ends, with the power Off.
And see if that helps.
And after that, probably the control console needs replacing. Or perhaps the controller board, if it shows any abnormality.
