LCD broken, need quick repair method

The quickest way to use the laptop again is to connect an external monitor (TV?) to the laptop's HDMI port and use it as the display. Press F8 to toggle between the laptop display only, the external display only or both on together.

I couldn't find a LCD panel replacement guide or video for your model online but if you search for Asus VivoBook F412DA LCD screen you will get results for suppliers of the part.
