This is an excellent guide. I replaced the screen on my macbook pro 13” retina early 2015. However, I am having some odd behavior from my fixed computer.
With the lid open, the computer does not seem to boot. However, if I close the lid (after booting or re-booting) the apple logo lights up and when I open the lid fully, the computer operates normally. Any idea what is wrong? I bought the screen replacement second hand on ebay.
