MacBook Pro A1398 EMC 2674 does not display video after LCD replacement.
I am pretty sure I followed everything correctly, but yet here I am. The new (used) screen I got for this model (SN: C02MT1KJFD58) for this MacBook Pro 15" Late 2013? model is part number 661-8310. I don't know where to find that part number on the original screen. Anyways, the old screen was busted, but would still light up. Now that I have attempted to put on the new screen, I can see the screen momentarily flash (as if it is on with no backlight), but nothing displays that I can ACTUALLY see with a flashlight. Also, the HDMI connection displays nothing and the unit seems to power itself down after a bit. Also, if you plug the magsafe in, it automatically turns on. Is that normal? I have tried hooking the old screen back up to it, but I also get no display. HOWEVER, we attempted to remove JUST the glass from the old screen, so we may have damaged it. :( Suggestions on how to get the new screen to work?
