Your issue is related to the backlight driver board which is within the display its self! Its not on the main logic board so any repairs to it won’t alter the backlight. If you see your desktop and its icons via a flashlight your GPU is fine!

Here is the needed part [product|IF185-124] and here is the guide you’ll need to follow [guide|1285]
 
You likely got a bad part and/or the wiring harness from the logic board to the driver board. I would inspect the harness at the hinge area as well as check the continuity of each wire as well as the possibility of a short to the case.
