Detection of Power failure
Projector provides a protection circuit to prevent the secondary failure when the power failure, fans failure or tempera-
ture failure occurs on the projector. The power failure detection lines "PF_5V", "PF_3.3V", etc. are connected to the
power supply lines and fans. When the failure occurs, IC801<SH3, CPU> receives an error information through the
ICs<I/O EXPANDER, IC5801, IC9912, etc.> and then outputs the signal "IC_RESET_CPU" from pin 186 to stop the
power supply.
