If you have the service manual then you should upload it. The service manual should have wiring diagram showing how all the boards are connected together.

This main board part number is 1AA4B10N22900_a N7AE, and on the actual tuner(where they say to get the correct number) it shows N7EJ. Why would it have a different number on the tuner than what is on the board?

There is zero voltage coming from the main board to the square board in the middle that the Tcon connects to. This has to be the problem.

It looks like the power is fed into connector K7D, I hope the service manual will tell you which pin that is.

But if there is no power coming to the board from the main board that means it is the main board, Right? I probed all the wires and get nothing.
