Troubleshooting
Detection of Power failure
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 "PF_3.3V_AD", "PF_3.3V_KS", etc. are
connected to the main power supplies. When the failure occurs, IC301<SYSTEM CONTROL> receives an error infor-
mation through IC5201<FPGA>, IC4801 <I/O Expander> and then outputs the signal "LAMP_DC_ON" from pin 32.
The signal "LAMP_DC_ON" is supplied to power supply circuit to control the power supply operation.
