If the motherboard model number is Asus X510UA V3.0 (apparently this board is used for F510UA as well) then ''if'' the replacement LCD panels are compatible, here are some images showing the backlight power circuit and backlight enable/disable circuit for the model.
I'm not that familiar with the way this circuit is drawn out and I don't know what component designation SL means but looking at the way it is drawn I think that component SL4505 may be a fuse with a package size of 0805, but as to its rating I have no idea.
Anyway check if there's a voltage on the eDP connector pins 37→40.

If not try to locate the component SL4505 and check if there is a voltage on both sides of the component or with the laptop turned off, if it measures 0.00 Ohms which it should

If not try to locate the component SL4505 and check if there is a voltage on both sides of the component or with the laptop turned off, if it measures 0.00 Ohms i.e. a short circuit, which it should
Normally there is voltage supplied all the time to the backlights and it is turned on and off ''in the panel'' by a voltage signal (3V-5V) on the backlight enable lead (pin 34 of eDP connector) so maybe check if the diodes (D4501) are OK or not.
I found this [link|https://thetechstall.com/asus-x510unr-60nb0gs0-mb4030-rev-3-0-boardview-file/|link] for a boardview of the motherboard, to show where all the components are located, but did not open it etc and I cannot verify the supplier or what info is needed to be supplied by you to download it. You may have your own sources and if not its your decision to use it or not.
