Hello, I have a black screen on a macbook pro retina late 2013. I already tried all the software fix like resetting NVRAM and SMC. i’m trying to find a way to be sure it’s a harware failure from the screen. The computer works fine since it’s booting and i can link it to a tv to see the desktop, so it’s not the graphic card either. The computer got water spilled from the ceiling on the left side of the screen and it got all the way inside through the keyboard. The water quantity was very small, still the mac gave out instantly. Now it’s rebooting fine but without the screen. I would like to find if the screen is done for good or if the connexion to the logic board is screwed. After opening the mac nothing seems to point that the logic board or the display cables have suffered. I have a working screen from a mid-2012 macbook pro i could install for testing but i dont know if it’s compatible. On the Ifixit shop the two screens have 50 dollard of price difference, although it has the same spec, also i dont want to mess with my working macbook. I know i could launch the apple diagnosis but it seems i cant make it display on another screen via HDMI. Any ideas to rules out possibilities ? Thanks for reading.
Shine a flashlight behind the screen where the apple logo is. On a certain angle of flashing the light you should be able to make out some text / image on the screen. If you can see it but very dim that would indicate that the MacBook has a no backlight fault. In this case I would leave the macbook turned off, open up the macbook with the bottom cover removed and unplug the battery to prevent further damage from water ingress as the longer it’s left untreated the damage will most of the time get worse and more components would need to be repaired. Here is a guide on removing the bottom cover and logic board: MacBook Pro 15" Retina Display Late 2013 Lower Case Replacement MacBook Pro 15" Retina Display Late 2013 Logic Board Replacement After removing the bottom cover inspect the display connector which is located at the top right hand side of the logic board for any liquid damage. You will have to remove the board to look in more detail on where the liquid may have went. There is a link here on general liquid damage cleaning but I don’t have the bookmark for it here, someone else will most likely post it here. Might not be too late to clean so you may want to try some 99% Isopropyl Alcohol brushing to remove some corrosion, take photos of where the corrosion is before cleaning it off because sometimes it may need more than just cleaning.
