If your screen fails to light up or is physically damaged, you most likely have a faulty screen that requires replacement.
To access the screen, you will first need to open your HP Pavilion 15-cd040wm by disassembling its back cover.
Before beginning, make sure to power off your laptop completely and disconnect it from any external power source. Once the back cover is off, be sure to disconnect the battery from the motherboard to ensure there is no power going to the laptop while it is being worked on.
