Blank Screen, backlight works(brightness), external display works.

my model is asus vivobook 15, k513e, screen suddenly went blank while i was watching something, i can still change brightness of backlight, but display doesnt output anything, tried reset, hard reset, unplugging the batery, reseating the ram, checked the drivers, i tried updating the bios but cant bcs bios can only put out on main display so i cant even enter the bios, so far there is probably something wrong with a connection but i cant find any videos for this specific laptop or atleast rly similar, dont really know what else i can do, i added some pictures, opened a laptop, i reconnected the lcd cable so its either dead connector/cable or the connector on the monitor, still hope the screen isnt dead

Update, it was the screen, gave the laptop to the repairshop and they fixed it (and destroyed my battery connector male and female part on the mb so now the laptop is stationary) xdd
