Has anyone come across an issue like this, and if so, what's a potential fix? Thanks all for the assistance.

I had this issue with an HP-22S. It is typical for not having enough pressure at the LCD contact areas. Separate the PCB from the LCD display, clean the contact areas with 50% isopropylalcohol and reattach the PCB. When fixing with the metal clips, turn them enough to get the boards pressed together properly.
