I left my charger on overnight and the Macbook was very hot in the morning. It wouldn’t turn on at all. Apple are charging too much for a repair so I’m trying to do it myself. When i took out the motherboard I think i may have snapped one of the black ribbon cables.

Well this is no information to start with at all, you don’t even say which cable you’ve snapped and how snapped it is.

Everything I’m finding is showing that a new logic board for that model is going to cost $200+ and I’m only seeing them on ebay.
