Switch Lite no buttons work apart from the home button.

The only button that works is the home button, all cables are fine, and I know the buttons work as I tested with a different motherboard and everything is good.

The odd thing is I expect maybe the buttons attached to the main board to maybe be bad but the left board should still work, which they do not.

I have tried resetting the Switch. I tried wiping it clean and starting from a fresh install, but still the same.

I don’t know much about the history of the board I am trying to get working other than the screen would work, LCD would work and it would run fine but it would display a black screen which I fixed.

I’m guessing there might be a chip that reads the movements of the controls which may have gone bad? It’s just weird that only the home button works. Any help would be appreciated!
