Chassis Description

The projector provides a protection circuit to prevent the secondary failure when the power failure, fans failure or tem-
perature failure occurs on the projector. The power failure detection lines "MAIN_6V_PF", "MAIN_-5V_PF", etc. are
connected to the main power supplies. When the failure occurs, IC801<CPU> receives an error information through
the power failure detection lines and turns off the signal "IC_RESET_CPU" output from pin 211 to stop the power
supply.
The power failure detection signals are sent to IC4801<I/O expander> and then sent to IC801<CPU>.
