Try pressing Fn+F6 (both together) to see if the laptop screen turns on.
Try pressing Fn + F9 (both together) a few times to see if the display output cycled between laptop screen only, external monitor only or both on together.
With the laptop turned on and a display showing on the external monitor, try shining a torch (flashlight) at an angle close to the laptop's screen and check if you can see any images on the screen. They will be ''very faint'' if they are there so trying this in a darkened room may help to see them if they are they.
''If you can see images'' then there's a backlight problem with the display. Either a faulty backlight power circuit on the motherboard, a faulty video cable/cable connection between the motherboard and the screen or a problem in the screen itself. Further testing would be required to find out what and where the problem actually is.
''If you can't see any images'' then there's either a problem in the video cable/cable connection or the screen.
Has the laptop been dropped or gotten wet at all?

If you suspect that it is a motherboard problem and not a display panel problem, here's a link to the https://realschematic.com/shop/11316/desc/asus-tuf-gaming-fx505dd-asus-tuf-gaming-fx505dt|schematics] that may help. (I couldn't find a free download online but the cost is not too bad)
