Introduction

If your Epson PowerLite Home Cinema 1040 (model V11H772020 or H772A) is overheating or producing loud noises, it could be an issue with a clogged or broken cooling fan. This guide demonstrates the steps necessary for replacing your cooling fan.

The cooling fan pulls in cool air and pushes out hot air generated by electric components in the fan. Without it working properly, the device may overheat and damage internal components, thus reducing the lifespan of the projector.

Before beginning, make sure to turn off the projector and unplug the power cord.
