MacBookPro 2012 15” A1398.
No visual damage was found.

Mac was inside of suitcase and it was inside of a bag.

Mac boots up,I can hear the chime,but the screen is totally black,not even “light” black. Caps lock light doesn’t work.

I tried SMC,PRAM reset, didn’t work.

Reconnecting screen display by unplugging those two things didn’t work. I used this video



Block Image



Reconnecting battery didn’t work.

I also tried SMC,PRAM reset while the battery was disconnected and Mac was getting energy from the charger. Didn’t work. I used that video.

What else can I do before changing the screen?I don’t want to swap screen cause it’s expensive.
