My late 2013 MacBook Pro 15" Retina MacBook Pro the screen flickers slightly, then 5 seconds later, the computer shuts down. It happens 10-15 ’s a day and makes it nearly impossible for me to work. The worst part is, the issue started happening after my warranty expired. Sucks! I have reset the SMC, run Apple Hardware Test, and clean reinstalled Sierra 10.12.2 and it still happens. I also have Coconut Battery installed and Battery is good, as well as, SMC Fan control. Average temp of CPU is 107 F. I also observed that it only usually shuts down when I’m connecting to a wireless connection. If I’m off wireless at home, I can usually run all day without a shutdown. I think maybe there is a bad solder or circuit on the motherboard, but don’t want to open the Mac myself. Paid almost 2k for this machine and it’s practically useless. HELP!!!!!!!!!
It might be your LVDS cable. Try hitting the clutch cover lightly with your finger tips and then move the screen back and forth really fast. Tell me what happens
