I might have damaged the inverter cable
I bought an LCD screen at ifixit website and decided to replace it on my own. When I bought the screen I used the model number A1286 and did not use the LCD part number. This model number has unibody and non unibody macbooks. I have to clarify that this is a non unibody according to everymac.
Everything fit but now I can't see anything on the screen. It is completely black. I tried putting the old broken screen but I get the same problem. Is it possible that I might have damaged the inverted cable? Or is it possible that the LCD screen I got is not compatible.
I am pretty sure that the computer is working fine since I hear the sound when it boots up and it was working prior to replacing the screen.
