Hi.
I can try to help you.
But you have to show good pictures because I don't know this model.
Finding a "fault" does not have to be difficult at all.

Ive see schematics of each boards...I'm very stunned for how Geeetech work.
Why why and why. Instead improve the revisions of board do all for make people crazy.
I've ask for replacement,and it's not right send me a board that have the same connector of previsious rev,but don't have the same pin.
Now I've have to rearrange all connections,watch very close the schematics (that it's wrong it too, cause don't respect the true position of physical pin,but it's reverse)
Hope i don't do errors and break this board.
For example that heat bed connector. Same connector for the same bed for the same board BUT.....with the pin that can't switch on the printer because it cause a shorcut (I don't lie... see schematics of rev B and rev V3)
Endstop connections,motors connections all to rebuild,recheck,and buy the right just connectors and crimping tool.
Hope do all connections property.
I'm very astonished

A very awkward situation arose which was unintentional.
Someone decided to send you a better version of the controller board, but probably did not know that the signal layout in the connectors is not compatible.
If the connector type is identical, the order of the wires in the connector can be changed without cutting the wires.
These plugs are disassembled and the pins can be removed from the body.
Somewhere in my thoughts I expected such a situation.

The problem is in the pin of rev b and rev v3.Same connector,but not the same signal.
