Epson PowerLite 83+ Fan Replacement

Introduction

Use this guide to access and replace the fan of your Epson PowerLite 83+ projector.

This is not a highly difficult fix, but it does require the removal of the main cover and the lamp. Be sure to turn the device off and unplug it from the power adapter prior to beginning this repair.
