Geeetech prusa i3 pro b Display Issue

Hi everyone,

i'm assembling a Geeetech prusa i3 pro b and i have assembled everything like the manual says.

But i'm having an issue.

When i only plug in the cable for the display and not for the SD, i can read the display.

When i plug in the cable for the SD slot, everything on the display is gibberish.. like unknown symbols.

i already tried reflashing the board with the official manual.

maybe someone knows my issue an can help me.

Kind regards
b4ron

The order of the wires in the plug may be confused.
Check the connections carefully.
