Introduction

Use this guide to replace a malfunctioning motherboard on the Olympus C-765.

The motherboard is a large, printed circuit board that controls all of the camera’s functions. A malfunctioning motherboard may be responsible for overall defunct camera operations. When a motherboard is bad, a camera may display a variety of errors, function slowly or may fail to start up at all. If the board is malfunctioning, it must be replaced in order to restore the camera to working order.

Be sure to consult the Troubleshooting guide before attempting to replace the motherboard. A slow camera may simply be solved by a system reset. A replacament only needs to be attempted if the reset does not work.

This guide will demonstrate how to complete this replacement process. The process involves multiple steps, including difficult steps like soldering.
