EN-ON/OFF voltage signal coming from scalar which is on IF BD will enable U1 to work. During start up, The voltage of SST_CMP is determined by Pin8(ISEN).When ON/OFF signal is off, MOSFET Q1 will be closed, then upper resister R22 give high signal to Q2’ GATE pin, and make IC’Pin1(SST_CMP) to GND, so IC will shut down. If giving a high signal to Q1, Q2 will be closed .then Pin1 will be floating. Once the voltage at the ISEN pin reaches the lamp on threshold, the IC switches from the striking mode to the normal operation mode and the PWM dimming control is activated. At the same time, the voltage of Pin1 will change following the voltage of Pin 8. R5 is limited current resister and C6 accomplishes the soft start function. DIM-ADJ duty cycle signal through R3 and C5 is on Pin 7(DIM), which will adjust IC’ output duty cycle, then changing the brightness of Panel The striking and operating frequency is determined by the external resistor (R4) connected to Pin 2. The striking frequency is 1.3 times of normal frequency. DRV1 and DRV2 of U1 are used to drive Q4. DRV1 and DRV2 are controlled by build-in PWM IC. DRV1 is reverse with DRV2.Q4 is built in 2 N-chanel MOSFET. DRV1 and DRV2’PWM signal 6 Service Manual drive Q4, this push and pull the energy in the transformer. The voltage signal on negative pole of ZD4 sensed through R35 comes to Pin4 of U1, ISEN (Lamp Current Detection & Control). The CCFL current is detected through R14and reaches a regulated value. The CCFL current detected at resistor R14 is converted to a voltage level and input to the ISEN pin.C12 is used to dump noise. Once the CCFL are ignited and current is sensed through resistor R14 .capacitor C12 performs the loop compensation function. The voltage at IC pin8 controls the drive duty cycle of the power MOSFET to regulate the CCFL current. 2.1.2) Output Circuit and Protection Circuit :( fig.3) CN3 1 2 NC CN1 1 2 4100-D02 R6 3 1K 3 4 ZD4 7 C18 BAV99 C17 3pF/3KV 15pF /3KV 2 10 1 SPW-054 T1 1 R14 390R 1% 6 CN2 1 2 C13 C19 3pF/3KV 4100-D02 C24 2700pF/50V X7R NC/220pF /50V X7R CN4 3 1 2 BAV99 2700pF/50V X7R OVP ZD6 NC R2 1K 2 3 C14 1 C15 NC/220pF/50V X7R ZD5 +5V 2 OVP 1 BAV99 +5V fig.3 C9 and C2 is the filter capacitance.R17 and C21 as the snubber circuit will decrease the peak voltage on Q4 drain pole witch have bad effort for MOSFET safety area.R18 and C22 have the same effect with R17 and C21.C8 and C27 will deeply decrease the voltage on Q4 drain pole. The transformer (T1) secondary winding leakage inductance and output capacitance(C18) forms a lower pass filter, which converts the square-wave driving signal into a sinusoidal output voltage signal for CCFL. The over-voltage protection feature is implemented by using an external capacitor devider(C13/C14,C17/C19) to sense the output voltage.The divide-down voltage signal is transferred though ZD5 and ZD6,witch will rise the OVP voltage ,then this OVP signal though Q3 determine the voltage of SST_CMP ,thus regulating the output voltage. If a CCFL is removed, fails or damaged during normal operation, CCFL current is no longer sensed and the voltage on ISEN pin drops. Once the voltage at the ISEN pin is less than the lamp” on” threshold, the shutdown timer is activated. The IC maintains the output voltage for approximately 2-3seconds and once the timer expires, the IC will shutdown. To restart the IC, either toggle the SST_CMP pin or recycle the power on the VDDA pin. 7 Service Manual 2.2 Power PWM circuit 2.2.1) Block diagram :( fig.4) Fig.4 2.2.2) AC Input and EMI Filter :( fig.5) L850 4 1 3 2 CHK-007 R851 499K R852 R850 499K 499K RT850 5R4A C852 0.47uF X2 C850 C851 222 Y 2 222 Y 2 F850 3.15A 250V 1 3 2 CN850 HF-301PCB 7MM fig.5 CN850 is a connector for connecting AC Power. F850 is a fuse to protect all the circuit AC. Input voltage is from 90V to 264V. R850 ,R851 and R852 are joined between two inputting main circuit to prevent man from shock. L850 is used to clear up low frequency wave. C850 and C851 are used to discharge the waves that L850 produced. High frequency waves are damped by C852 8 Service Manual 4 D850 BL4-06 R839 + 1 - 0.2R/1W FUSE C854 68uF/450V R841 27K 2 C875 472P R842 R856 10R 7 VCC NC 8 D851 FR10-10 SF10-04 10uF/50V Signal_GNDR844 5 D841 4 9 8 47R NC/1N4148 RT 3 4 D852 C855 0.01uF/50V X7R 5 11 10 27K C849 U850 LD7552B 2 R855 499K OUT NC/P6KE170A 27K R843 VCC D853 R854 499K 3 12 R853 499K Signal_GND T850 SPW-119 1 R848 100K 1% 7 C860 AP2762 2 C872 NC/100P/1KV Y 5P 332 Y 1 3 C846 6 Q850 1 3 2.2.3) High Voltage to Low Voltage Control Circuit :( fig.6) NC/47pF/50V X7R GND COMP CS 6 R840 47R 1 Signal_GND 2 Signal_GND C848 C847 1nF/50V X7R 1nF/50V X7R Signal_GND R884 10K 1 T851 NC 12 R859 0.75R/2W 1% 2 Signal_GND 11 10 3 9 4 5 8 6 7 fig.6 D850 is a rectifier in which there are 4 build-in diodes, inverting AC to DC. C854 is used to smooth the wave from rectifier. R839 is a fuse resistor to protect the following circuit when inrush current is too large. U850 is a highly integrated PWM controller. Typical start-up current for U850 is only 30 uA, R841, R842 and R843 are serial circuit to limit current flow. When current flow through R838 and R839 gets to Pin 3 of U850, with VDD hold-up capacitor C855, U850 is enough for starting up. When U850 begins to work Pin8 of U850 will output square wave to drive Q850, and then the main current flow get to GND bypassing through T850, Q850. Because of the change of current flow, wires in the other side of T850 will induct current. At the same time, the current inducted by wires which connected T850 Pin 1 and Pin 2, with components of D852, R855, C855 and C849, will be supplied to U850 for normal operating. When the sense voltage across the sense resistor R859, reaches the threshold voltage around 0.85V, the output GATE drive will be turned off. Every time when the output of power supply is shorted or over loaded, the FB voltage will increase, the build-in PWM output will then be turned off. Both will prevent the power supply from being overheated under over loading condition. The PWM duty cycle is determined by this current sense signal and VFB, the feedback voltage. When the voltage on sense pin reaches Vcomp = (VFB-1.0)/3, a switch cycle will be terminated immediately. Vcomp is internally clamped to a variable voltage around 0. 85 V for output power limit. When Q850 are turned off, the main current flow will be consumed through D851, C875 R853 , R854 and R855. This will prevent Q850 from being damaged under large current impulse and voltage spike. 2.2.4) DC_12V and 5V Output Circuit and Feedback circuit :( fig.7) 9 Service Manual C862 1000pF/1KV X7R R862 10R 2W D854 SR520 D855 SR520 C873 1000pF/1KV X7R D856 D857 L855 NC/CHK-XXX +12V C863 470uF/25V C864 470uF/25V R887 20K R873 10R 2W NC/SB5150 L854 CHK-XXX F851 SB5150 +5V 5A/125V C858 470uF/25V C856 C857 470uF/25V C876 470uF/25V 0.1uF/50V +5V R857 270R R871 R872 270K 3.6K ON/OFF DIM 1 2 3 4 5 6 7 8 CN853 +5V +5V GND GND ENA DIM Audio_detect Audio_on/of f SIP-8P R858 NC/5K1 R860 I851 TL431 5K1 C871 0.1uF/50V C859 10nF/50V Y 5V R868 3.3K fig.7 D854 is used to rectify the inducted current. R862 and C862 are used to store energy when current is reversed. The parts including C863, C864, and R887 are used to smooth the current waves that are from D854 and D855, and then 12V voltage is supplied. We can see, there have two parts C862 and R862 paralleling with D857,they have two functions ,One is used to damp the peak voltage of D857, the other is used for EMI. D857 is used to rectify the inducted current. R873 and C873 are used to store energy when current is reversed. The parts including C856, C857, C858 , C876 and L854 are used to smooth the current waves that are from D857, and then 5V voltage is supplied.C873 and R873 have the same function with C862 and R862. In order to limit the 5V and 12V over Spec, we need a sampling circuit to accomplish this function. At first, use R871 ,R872 and R868 this divider circuit to sample 2.5V, and comparing it to a reference voltage 2.5,so we will get a differential signal witch can control the current of I851(TL431). R860,C859 and C871 is frequency compensating circuit witch be able to control feedback loop speed rate,R857 is else able to accomplish this function, and its main task is getting current for I851 and I850 2.3 I/F Board Circuit (see the Attachment 2- Schematic) 2.3.1 RGB CAPTURE - Signal RED,GREEN,BLUE input through CN102 #1,#2,#3, Stop DC via C113, C114 and C115, and then enter into U105 (TSUM1PEJ-LF-2) analog input PIN #28,#25,#23, and then TSUM1PEJ-LF-2 deals with signal internally.
