Mechanical Switch
When the lamp cover, bottom cover, air filter are not fixed securely, the projector can not turn on because of one of
the following detection switches is turned off.
- Lamp Cover Switch (SW902, SW905)
- Bottom Cover Switch (SW904)
- Air Filter Switch (SW903)
Lamp type detection switches (SW906, SW907, SW908, SW909)
These switches are for detection of the lamp type. The signals "LAMP1_SEL1", "LAMP1_SEL2", "LAMP2_SEL1",
"LAMP2_SEL2" output from switches SW906, SW907, SW908, SW909 are sent to pins 46, 47, 48 and 49 of IC4802<I/
O EXPANDER> and IC801<CPU> through the parallel bus lines.
The LED drive signals are output from pins 10 to 18 of IC4802<I/O EXPANDER>. The drive signal for the POWER LED
is output from pin 211 of IC801<CPU> as "POWER_SW_CPU" and applied to LED through the IC5825<BUFFER>.
