Introduction

Are there gremlins in your projector? Is your new projector's functionality in general disarray? Are you have trouble with hooking up your projector through USB or HDMI cable? Well, then you may need to replace the motherboard, and this guide will help you do that.

Before continuing on to the processes of taking this projector apart and ripping out the brains, I would do a few simple checks to makes sure it's not something else that is causing the issues. I would make sure that your projector is not in a spot where it could overheat. Say, in a corner or directly up against a wall with no ventilation. Then I would try factory resetting the projector, which could work out bugs in the system.

Before beginning make sure that the projector is unplugged from it's power source and is on a level sturdy work surface.
