S7 Screen Not Working But Working With Different Motherboard

I have an S7 with no display, it makes noise and you can hear the screen working when you tap it but there isn’t a single pixel lit up, I tried another motherboard on the same screen and its working fine so it isn’t the screen. So it’s something on the motherboard but what would it most likely be?

Answer this question I have this problem too

I would first check the LCD FPC connector on the motherboard. Look for broken, bent, burned, or corroded pins on the connector or loose/broken pads on the motherboard where the connector is soldered to. You might try posting a high-res photo of the board around the connector

I've looked at the LCD connector and there isn't any damage at all, it's mint. There is no water damage etc as well.
