No backlight whatsoever and no display

So I currently have an iPhone 6 Plus with no backlight whatsoever. Obviously no display as well. I've tried swapping out the chestnut backlight ti chip as well as one backlight driver and still no success. Tested backlight caps and found no shorts and physical lcd connector itself is good...all pins making correct contact with components.

No liquid damage as well. There was a couple solder blobs under the cpu shield upon removing which I'm learning is quite common.

Does anyone have experience with this issue and can point me in the right direction. The less heat I have to put near the cpu the better. My next step to try would probably be one or both diodes.

Coil looks near perfect as well.

Any help would be very appreciated, thank you!
