Display assembly replacement on backlight failure?
Hello,
recently my Macbook pro (late 2013, Retina) 13", made a silent "puuk" sound and the display stopped working. Apple authorized service said - after a diagnosis - that I need display assembly replacement due to the backlight failure. It is weird because backlight chip & fuse is on the board. Can they have right?

Sure the tires are round and so is your cars steering wheel! So replacing it will fix your flat tire ;-]
Your right! The logic is part of the main logic board. While that is true lets properly diagnose the issue first.
So using a flashlight shine it through the Apple logo (a poor mans backlight) are you able to see your desktop and its icons? If you do then the circuit issue is likely the main logic board. Take the bottom cover off and locate the display connector in the top right corner how does it look clean and shiny or dull and corroded?

The laptop is in Apple service now. I will take it back after weekend and - with your help - try to diagnose the (real) damage. Thanks for the trick with flashlight backlight. I only took cover off and IPA cleaned signal connector. The were no oxides there. Laptop itself is working, excluding the screen. I have a multimeter and soldering station, but have no motherboard scheme.

I finally got laptop back. Flashlight on Apple logo makes a nice tiny backlight. I see a part of a login screen. @danj , could you guide me through the diagnostic procedure?
