Ideapad 3 15IAU7 82RK002SCF backlight fuse location

So I have a Lenovo Ideapad 3 15IAU7 that needed a screen replacement, I ordered one online and replaced it without disconnecting the battery first. New screen is black, computer runs and if you angle a flashlight at the screen you can just barely see the screen. After some research into the situation I’ve come to realize the backlight isn’t working correctly, more specifically I can almost guarantee myself I’ve blown the backlight fuse. So I’ve dissected the laptop, I have the motherboard out and the board in my laptop is a NM-E341 REV: 1.0. I’ve scoured the internet for the schematic diagram, an actual tip leading to location, a name like the ones printed on the board itself, Ive even traced back from the screens backlight pin all the way to the pin it would match up to on the motherboard (pin 22 I think? I’ve added photos)

but there’s a component on the motherboard directly above the port for the EDP cable that makes it almost impossible to follow the trail. (I’ve added pictures as well). If anyone can help me find the document(s) or maybe even tell me themselves I’d really appreciate the help as it’s a work laptop I really can’t afford to lose.

bbmh hanlon Pin 22 is your BL enable. What voltages did you get on pin 26-29? Set your meter to VDC and black to ground and red to each pin. If you have no power on it, it could be a fuse or the boost circuit.
