If the display is not powered when the voltage is connected again, please restart from point 1. Most likely there is no issue with the display but a missing connection of the PIN’s. This can happen whilst assembling the display show in figure 4.
Check the PIN’s on the board before clicking on the display board the second time, see Fig. 4.
