Laptop Black Screen

[SourPotato]

On startup, my laptop screen is black. No image if I shine a flashlight and I can plug it into an external monitor just fine. All my video drivers and BIOS are updated and the cable wasn't loose after a recent repair. What do I do now?

Take it in for repair.

Sounds like your screen has failed or the video cable needs replaced.
