Introdução
If your Lenovo IdeaPad 1-15IJL7 laptop indicates that it is on, but does not display an image, it is a possibility that there is screen damage. Some factors for this are malfunction in the LCD panel, a loose display cable, defective RAM, and faulty graphics.
In this tutorial, we will guide you through an effective replacement of your laptop's screen. You will be uncovering the external laptop backing, which will expose the internal components. The hinge and hinge cover will need to be removed in order to access the screen itself. The camera will not need to be removed.
This Troubleshooting Guide should be referred to before starting any replacements. As always, power off your device before starting, and check laptop settings to avoid any other damages.
