I just replaced my screen with a 3rd party one and it is extremely dark to the point where I can't see the screen unless I shine a light on it. It won't respond to the brightness keys and the brightness in settings. I was very careful with the connections and there seems to be no visible damage. I have also tried reattaching the original screen and testing it but I had the exact same results. Any help would be appreciated.

    It sounds like the backlight isn't working. You may have left something loose or the screen you put in isn't working right. I don't believe your laptop has a separate cable for the backlight, it's just part of that eDP cable that runs from the motherboard to the display. Is there any chance the screen is the wrong one?
