Introduction

Electronics are a big part of our lives and when they break it can be a great inconvenience. An LCD screen can stop working for many reasons such as the device’s old age, overheating, or impact damage. A screen that isn’t working properly means the potential loss of important information like passwords, class notes, or childhood pictures.

As a note of precaution, please be aware that the LCD screen is connected directly to the motherboard and assembled with the front frame. Remember to carefully follow the instructions so as to not damage your device as a whole.

This guide requires soldering, please visit the How To Solder and Desolder Connections guide for more information and advice.

Look at the teardown guide for instructions on general disassembly.
