Epson PowerLite 77c Fan Replacement

Introduction

The fan is an essential component to keep your projector cool and functional. Before replacement, first check if there is dirt or dust clogging the fan's blades. Use an ESD-safe brush and/or compressed air to remove any dirt or dust buildup, then test the projector. If cleaning didn't solve the problem, and/or damage is visible, replacing the fan is the next best step. Before replacing the fan, make sure the projector is turned off, and allow it to cool completely before beginning.
