Wonky Display on an HP E3610A

The display on my HP E3610A power supply started acting wonky (technical term). As the unit warmed up, the ammeter values would jump around erratically, with the display occasionally blanking out entirely. After resoldering the terminals at both ends of the display board cable, the display returned to her usual rock solid self.
