Purpose of the Light Sensor in the Light Pipe

the controller of the projector read the measured values of this light sensor and, if required, sends corrective information to the Lamp
Power Supply (LPS).
The left cover has to be removed from the projector to replace the Light Sensor Module. This procedure as-
sumes that the left cover is already removed from the projector.
Necessary tools
• TX10 Torx screw driver.
