Introduction

This guide is to show you how to replace the SD card board. On the SD card board is not only the SD card reader itself, but there is also a micro switch that tells the camera if the battery door is closed. The camera will not turn on unless a signal is giving to the camera that the battery door is closed. Being that it is a small plastic switch, it is sometimes prone to breaking or having debris prevent it from working properly, stopping your camera from turning on.

The Phillips #000 screwdriver is marked as an optional tool as you can always use the JIS #000 screwdriver in its place (JIS screwdrivers won't damage Phillips head screws).
