If your Epson PowerLite Home Cinema 1040 (model V11H772020 or H772A) fan constantly runs even right after you turn the projector on and the lamp is still cool, there could be an issue with the temperature sensor. The temperature sensor in the Epson PowerLite Home Cinema 1040 is a green chip about the size of a nickel. It has 2 wires that plug into the motherboard. If there is a malfunction with this sensor, the projector will constantly think it is overheating, and the fans will constantly run and the projector may even shut off.
This guide demonstrates the steps necessary for replacing your temperature sensor.
Before beginning, make sure to turn off the projector and unplug the power cord.
