Chosen Solution
Hi Everyone, This issue has been plaguing me for close to two years now. Anytime I close the lid and reopen it, the keyboard lights up (and sometimes fans go on), but the screen remains black (no backlight either). The only thing that brings it back is resetting the SMC and having it reboot. This issue started happening around the time I replaced my fan after the bearings started going/rattling. I suspected I may have damaged something, maybe the logic board, but I am pretty clueless about the internals of a Mac. After seeing the price of donor boards, I sort of gave up hope. I just recently replaced the display cable hoping it would fix things but no dice. I also learned about flexgate, but I’m not sure how to check if those cables are damaged. I have tried shining a flashlight into the display after closing and opening the screen, but there’s nothing. Just darkness. The good news is everything else about the Mac seems to work fine outside of being able to close it and take it places. I’m very much out of ideas, so any assistance would be much appreciated. Thank you in advance! Diagnostic Result

This is also the original battery the system came with which is now over four years. So its time for a new battery and I’m suspecting this will solve your problems!
