Troubleshooting
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 "PFAIL_S5V, "FAN_ERR1", etc. are connected
to the power supply lines and fans. When the failure occurs, IC301<SYSTEM CONTROL> receives an error informa-
tion through the ICs<IC5201, IC1801, etc.> and then the operation of power and ballast will be stop by the control
signals, "DC_ON", "BALLAST_AC1", "BALLAST_AC2".
