connectors are keyed, but i cut them on 1 side to connect them twisted, i've tried every possible connection that way, still nothing.
so it sounds like a hardware problem if i get it right, i gonna test the cables next, but don't know how to test board with multi-meter or some other way, anyone can help? i dont have another lcd module so i can't test with other one.
