Can't access bios via External Monitor

No longer needed.

In Control Panel>Display section, is the external monitor set as Extended Display? If so, BIOS has no no way of knowing the laptop screen isn't working so it's displaying on the dead screen. Switch to an alternative setting so that it only shows on the external.

Try removing the LCD screen or just unhook the cable connected to it then connect an external monitor.

Check if it reads the external monitor as the main display.
