-89-Chassis Descriptiondetection 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 "P-FAIL_S5V", "P-FAIL_S3.3V", etc. areconnected to the main power supplies. When the failure occurs, IC301 receives an error informationthrough IC5201, IC4801 , IC5281, IC5082, IC4081 and then outputs thesignal "LAMP_DC_ON_EX" from pin 32. The signal "LAMP_DC_ON_EX" is supplied to power supply circuit as thesignal "LAMP_DC_ON" via IC1871 to control the power supply operation.Error information tablePower failure detection systemIc Pin Signal Name connection Lines error Information Failure AreaIC5281M623205 P-FAIL_PJ 5V_NET, 3.3V_NET PJ_NET, S5/3.3V 3.3V, 5V on Network Joint6 P-FAIL_S5V S10V, S5V_ALG, S5V MAIN/AV, S10/5V S10V, S5V on Main, S5V on AV7 P-FAIL_S-5V S-6V, MAIN, S-6V S-5V, S-6V on Main9 P-FAIL_S1.2V_FRT S1.2V_FRT_INT FPGA, S1.2V S1.2V for FPGA on Main11 P-FAIL_S1.8V_KS 1.8V_KS, S1.8VSK_KS,S1.8VMPLL_KS, S1.8VAA_KS KS, S1.8V S1.8V lines for Keystone on Main12 P-FAIL_S2.5V_KS2.5V_KS,S2.5VAC_KS,S2.5VAB_KS,S2.5VAA_KSKS, S2.5V S2.5V lines for Keystone on MainIC4801TE7783 61 P-FAIL_S3.3V_KS 3.3V_KS, S3.3VAA_KS,S3.3VAB_KS KS, S3.3V S3.3V lines for Keystone on MainIC5082M623206 P-FAIL_1.2V_HDMI 1.2VSI HDMI, 1.2V 1.2V for HDMI on Main7 P-FAIL_RLY S12V_MIR, S12V_MIR1,S12V_MIR2 RELAY, 12V S12V Relay on Main9 P-FAIL_3.3V3.3VSI,3.3V_AD,3.3V_ADA,3.3V_ADD, 3.3V_ADX, 3.3V_ADR,3.3V, 3.3V_PNLMAIN, 3.3V 3.3V lines on Main10 P-FAIL_5V 5VSI, 5V_CTL, MAIN. 5V 5V lines on Main11 P-FAIL_15V 9V_LNS_SHT, 15V_LNS_MIR,12V_FIL, 15.5V_PNL, 15.5V_OP MAIN, 15/12/9V 15V, 12V, 9V lines on Main.
