Introduction

One of the most common problem associated with the BenQ HT1075 projector is overheating. Since all electronic equipment depend on the transfer of energy, components will eventually warm during run time. This is especially the case for projectors which also use bulbs that produce even more heat. Therefore, it is critical to keep a functioning fan at all times. This guide shows how to replace the projector fan, but it is also important to keep the fan clean from dust and particles that can potentially slow it down.
