Chosen Solution
When I try to boot up my mac it doesn’t turn on at all. It’s charged and I’ve tried different chargers and they all work fine. A similar problem happened in the past where it shut down after the Apple logo appeared when I tried to boot it up, and I solved that by restarting it one of the times I was able to get onto the lock screen. This time around it’s not even getting the screen turned on, except one time where I couldn’t get to the restart button in time. I’ve tried giving it time to just sit there, however it seems broken.
From what it seems, the LCD could have gone out. Have you tried to hook it up to a tv or monitor?
