Was hoping someone may be able help. I'm a noob so bear with me.

I had troubles with the TBS on my D&D so ordered the replacement from Great Lakes. I am trying to install the new set but can only get the transmitter board to work. When I install the receiver board I get the "missing 3 balls" error. The original boards and moles connectors are pretty hacked up so I'm thinking maybe the previous owner re wired something. I have included pictures of the original board hoping someone can help. Many Thanks

Thanks for the reply. Mine appears to be the same(ish) but I have included a couple more pics. The original board does work it is the Great Lakes replacement that I cannot get to register. It is like there is no power going to it. Should I be looking somewhere else for the fault as the fact that the original board still works suggests the wiring is fine? Should I redo that shoddy 6-pin molex connector? Apologies again for the newbie response/questions.

Thanks
