However, the display has a faint digit partially lit in the second block of leds, it can be seen in the last picture
I'm figuring a defective block, but any suggestion is, as always, very welcome

Hello Alberto,

Such ghost segments sometimes are due to corrosion on the main PCB: this results in a shortage between the driving lines of the display. Careful inspection and cleaning will help !
