A1398 Late 2013/Mid2014 MacBook Pro... No LCD Display
We had a cracked LCD on this model but still had 80-90% working display on the screen. We replaced the LCD, and screen was completely black. Assumed it was defective, so we ordered a replacement and installed.. and again no display.
We tested the HDMI display and got a perfect signal... computer is working great.
I can believe that we received two defective LCD's in a row, but I find this highly unlikely. Any other ideas?
Is this a good question?
