@x4leeb you have not told us what components and where you have checked nor have you told us what 820-xxxx number your logic board is.

@x4leeb you have not told us what components and where you have checked nor have you told us what 820-xxxx number your logic board is. It would also be good to know more about this"if it had sustained heat damage". what kind of heat damage?
Since you do get power from your Magsafe, you want to check your DC in fuse. You can check it for power when you have your MagSafe plugged in and show power on the connector or you can check it for continuity.

Now, I am making the assumption you have the logic board out of the chassis so you can actually check the circuits. Also, you do have a fairly decent multimeter and know how to check basic components. If so, you do want to post some large, well focused pictures of both sides of your logic board with your Question. That way we can see what you see and hopefully guide you all the way through.
