-Hello, i have a1398 15" Retina display mid 2014.
+Hello, I have A1398 15" Retina display mid 2014 MacBook Pro.
I was cleaning display and during doing it I put the brightness at min level. After that when I turned on brightness, I got half of the LED backlight LEDs not working, and flickering, then after 5-10 minutes, backlight is gone, the Apple logo at the rear not shining either.
-If I shine flashlight at the logo, I can see login screen at the screen. The MacBook works fine with an external display.
+If I shine flashlight at the logo, I can see login screen at the screen. The MacBook works fine with an external display.
-I did all resets, nothing helped. So, as i investigated the net and this site, it could be backlight fuse. So I did disassemble plugged unplugged wires, looked for visible damage of components tried to locate backlight fuse, but unfortunately I have a newer version of logical board https://47dqy71du7e1rvs1n3ezfll1-wpengine.netdna-ssl.com/wp-content/uploads/CMP-5814-UTW0_WEB.jpg

I guessed that the fuse is yellow one with "P" sign on it or a big green near it. Does any one know where fuse and driver located on this logic-board?
P.S. When I got that issue, I got the feeling that my (not hard) pushing the screen with napkin during cleaning caused this problem, could it be?
