I have a zephyrus g16 and my laptop screen isnt working it only works when i connect it to my external monitor

I need help. Whenever im not using my monitor the screen doesnt work although i know its on because i can hear the launch noise and when i connect it to my other monitor with a hdmi cord it works. I reset my graphics drivers and everything
