はじめに
The computer screen is responsible for displaying all of the visual output contained in the laptop. A broken or malfunctioning screen can show varying symptoms including signs of damage such as cracks, inconsistent resolution or coloration, black spots, screen flickering, or complete loss of image display.
Absence of any image on the screen could be caused by problems with other laptop components, so review the troubleshooting page to rule out other possible causes.
Make sure that you power off and unplug your computer before beginning.
The LCD is adhered to the digitizer / touch screen with double-sided tape around the edge, so it is relatively straight-forward to replace it without having to replace the entire assembly.
If there is a possibility you will need to replace the LCD adhesive and want to have all parts on hand before you begin, read through the ASUS VivoBook S400C LCD Adhesive Replacement guide and consider ordering the 3 mm Double Sided Adhesive Tape.
