Re: HP 182T display/8559A SA - display only visible with beam find.

Well at least the problem is big and bold. When just beam fid works it will be any of the following. Blanking Z is cutoff for some reason. X or Y or both are totally unbalanced. Typically some sort of supply failure if you find the delection all the way to one side. But if just x or y then most likely a transistor in that deflection circuit. Generally reasonable to find. Good luck Paul WB8TSL
