Internal display flicker, then black, now not recognized in device manager

Hi, having a problem with my GU502GW ROG Zephyrus. The internal display flickered, then turned black.

Tried a 40 sec power button reset with everything disconnected, this allowed me to see the display again for a short time, but then the same issue occurred. For a while, the display was visible in the Device Manager, but now only shows under "hidden devices".

The Asus ROG symbol shows on boot but quickly turns black. It seems like the screen hardware is okay, but is not being recognized.

I have also tried updating all drivers to those shown on this page: GU502GW - Support

I forgot to mention, my external monitor functions completely fine. No issues.
