Chosen Solution
I am in desperate need for answers. Today I plugged my Macbook Pro Retina Early 2015 into an Arduino Uno to upload code to it and my computer went black. I tried to reboot it and got the startup noise but nothing showing on the screen. I reset PRAM and SMC to no luck. Hooked it up to an external monitor and it works fine. This computer has no history of liquid damage. I opened it up and cleaned and reset both ends of the LVDS cable and still the screen is back. What could possibly have happened and how can I fix it.
If I understand it the external is working but the internal is not visible when you shine a flashlight in from the Apple logo in the lid if that’s correct your internal display cable (iDP or also called a eDP cable). Let’s disconnect the cable from the logic board and take some pictures of the cable connector from both sides and also take some pictures of the logic board connector so we can see connector and look into the connector and post them here for us to see Adding images to an existing question
