The mac starts with sound, you get to login but black screen
I ask for advice on a MacBook Pro 15 A1268, always kept with care that presents the Black Screen problem.
I know it is a topic covered thousands of times and I have read the discussions but I would like to understand how to solve the problem. the GPU doesn't seem to be the problem, I read that even a user solved it by replacing the trackpad.
I think it's a sensor problem, which doesn't trigger the screen. I tried to disconnect the sensor that indicates the battery level but the result does not change, I tried everything but nothing to do.
I have a mini-display port adapter because I wanted to test if the video output worked but I don't think it's compatible since the port is thunderbolt.
does anyone have any idea how to understand if it is a sensor and try to get it back to life? I also cleaned the thermal paste, everything..
I hope for your help, thank you
