Lamp cover switch (SW902)
The lamp cover switch (SW90) 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 replac-
ing the lamp ass’y, place the lamp cover correctly otherwise
the projector can not turn on.
Thermostat (SW901)
There is the thermostat (SW901) inside of the projector to
detect the internal temperature rising abnormally. When the
internal temperature reaches near 100˚C, the thermostat
opens to stop the operation of the power supply circuit.
The thermostat will automatically return to normal condi-
tion when the internal temperature becomes normal (about
60˚C).
