-80-TroubleshootingDetection of Power failureProjector 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. areconnected to the main power supplies. When the failure occurs, IC301 receives an error infor-mation through IC5201, IC4801 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.Error information tablePower failure detection systemIC Pin Signal Name Connection Lines Error Information Failure AreaIC5201XC3S50A112 PF_3.3V_AD D3.3V_AD AD, 3.3V 3.3V AD on Main156 PF_3.3V_KS 3.3V_KS KS, 3.3V 3.3V Keystone on Main157 PF_2.5V_KS 2.5V_KS KS, 2.5V 2.5V Keystone on Main57 PF_1.8V_KS 1.8V_KS KS, 1.8V 1.8V Keystone on Main152 PF_3.3V_GAM 3.3V_GAM GAMMA, 3.3V 3.3V Gamma on Main151 PF_2.5V_GAM 2.5V_GAM GAMMA, 2.5V 2.5V Gamma on Main251 PF_1.8V_GAM 1.8V_GAM GAMMA, 1.8V 1.8V Gamma on Main55 PF_5VS1 S5VI HDMI 5V 5V HDMI on Main191 PF_3.3VS1 S3.3VSI HDMI 3.3V 3.3V HDMI on Main56 PF_1.2VS1 S1.2VSI HDMI 1.2V 1.2V HDMI on Main59 PF_S3.3V S3.3V MAIN.
