After uncommenting the REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER, the display is blinking and no characters are shown on the screen, I have already switched the cables between EXP1 and EXP2, but it did not succeed.

    This question could use some more information and pictures. It is a fact that some of the cheap displays have the EXP ports upside down, I have had that myself so I cut out some slots for the notches on the cable connector. – 0scar Jan 29 '19 at 23:17

this problem can be solved by turning the slots on the display, as in the image below. Some Chinese displays are inverted from factory.

  • Yes, my experience was the same, I didn't know you could turn the plastic all the way around, good to know for next time! I just cut some extra slots... – 0scar Jan 30 '19 at 22:11

    I've just switched the slots and it worked like a charm, it made my day! – David Souza Jan 30 '19 at 22:43
