Did buy a HP53132a counter mainly to use with the RS 232 for high resolution and to have a backup for my very favorite 5345a with 40 GHz head. Sadly the very clean unit has a very weak display to the extend that an 8 looks like a 9. Have the option for a full refund but would like to explore alternatives. Any ideas.
Some VCR's with VFD displays had this same issue in 80-90's. It was usually dead (dried) electrolytic capacitor somewhere in VFD drive circuits, causing poor drive voltage levels. After replacing the dead capacitor the display was as new.
