If your original lcd-digitizer assembly was refurbished, the digitizer could have been stressed to make it failure prone. LCD's are easily damaged, depending on the refurb and bonding process. Liquid (LOCA) glue residue found near/on flex cables is often a hint.

If your replacement lcd-digitizer assembly was refurbished, the digitizer could have been stressed to make it failure prone. LCD's are easily damaged, depending on the refurb and bonding process. Liquid (LOCA) glue residue found near/on flex cables is often a hint.
Also, another good possibility involves the flex cable connectors themselves. Did the replacement LCD-digitizer cables have foam pads on the back side of the connectors or just shiny metal? If those foam pads aren't there, when you go to place the connector's cover with the 3 screws, any one of cables have room to pop off when positioning the display.
When you press down on the display, it may be enough to flex the display and temporarily or partially make a connection at the cable ends (upper right corner of screen) underneath and/or nudge a defect (crack) present in the digitizer panel, which is just below the glass surface.
