Introduction

This guide will go through step by step on the replacement of the motherboard on a Sony Alpha A350. These steps will include removal of all screws, wires, ribbon strips, eye cup, front case, and rear case of the camera in order to safely pull the motherboard out of the main device. The motherboard plays an important role in image processing and it has a major influence on the quality of the eventual image that is produced. The motherboard will need replaced if the camera is not powering or turning on. (Especially if the camera has been subjected to outside trauma such as a drop or water damage.) Replacing the motherboard will help in fixing the camera to work again.
