Hey Everyone, I have a mid-2012 i5 Macbook Pro that had the screen suddenly go black (or a very dim black). I took the entire display LCD out, and there is still a backlight. It dims or brightens in accordance to F1 or F2 buttons. So it isn't a back light issue. The image is just a dim gray on it, but you can see the light is working fine. I've replaced the logic board for other reasons, and got a new LVDS cable - So it isn't those components. Is this a setting? Or could the LCD screen go bad but still have a backlight? Thanks in advance!
