Lenovo Thinkpad X1 Carbon 4th Gen Display Replacement

简介

If your Lenovo Thinkpad X1 Carbon 4th Generation is experiencing black screens or going blank randomly, use this guide to replace the screen (also known as the display).

The screen uses a ribbon cable to send the information to the motherboard. A loose ribbon cable connection will cause the same issues like a broken screen.

Before using this guide, inspect the ribbon cable connection for a loose or non-existent connection, which has the possibility of making the screen dysfunctional. Be sure to fully reassemble the computer before testing the screen.

Before beginning, make sure to power off your computer completely and disconnect from any external power source.
