I also thought that was the issue at first. I’ve tried reconnecting and putting more slack/less slack but the symptoms stay the same. Plus, if it was worn out from open/closing the screen, I think it’d affect the backlight as well as the display when I wiggle the screen back and forth. But they’re both is stable from what I see.
I’m confident it’s that capacitor since I can see the pads aren’t rounded but jagged (there are rounded ones on the board, and I know those are supposed to be empty). That would suggest that the capacitor was torn off by the plastic of bevel of the display assembly being pushed in too far. I can also see that there’s a hole in the protective tape covering board, right where the capacitor should be. It’s a bit awkward to describe but yeah. Plus, the previous owner also described scratching that bevel and symptoms showing up after they did it too often. So all in all, I’m pretty sure it’s the cap. Still, thank you for the answer!
Thanks for the clear and concise answer, my man. Cheers!
