Circuit Protections
Lamp cover switch
The lamp cover switch cuts off the drive signal to the lamp
circuit when the lamp cover is removed or not closed
completely. After opening the lamp cover for replacing the
lamp assy, place the lamp cover correctly otherwise the
projector cannot turn on.
Thermal switch
There is a thermal switch inside of the projector to detect
the internal temperature rising abnormally. When the
internal temperature around lamp reaches near 120°C
(±5°C), the thermal switch will open to cut off the power
supply to the lamp power circuit.
The thermal switch is not reset to normal automatically
even if the internal temperature becomes normal. Reset
the thermal switch following to the procedure below.
How to reset the thermal switch
1. Remove the cabinet top case.
2. Press the reset button on the thermal switch.
Caution:
Before press the reset button, disconnect the AC cord
from the projector.
This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the
projector, it will automatically turn off by operating one of the following protection circuits.
