Chapter 1- PRECAUTIONS & SAFETY NOTICES
1. SAFETY PRECAUTIONS
This monitor is manufactured and tested on a ground principle that a user's safety comes first. However, improper used or installation may cause damage to the monitor as well as to the user. WARNINGS: This monitor should be operated only at the correct power sources indicated on the label on the rear of the monitor. If you're unsure of the power supply in you residence, consult your local dealer or Power Company. Do not try to repair the monitor by yourself, as it contains no user-serviceable parts. This monitor should only be repaired by a qualified technician. Do not remove the monitor cabinet. There are high-voltage parts inside that may cause electric shock to human bodies. Stop using the monitor if the cabinet is damaged. Have it checked by a service technician. Put your monitor only in a lean, cool, dry environment. If it gets wet, unplug the power cable immediately and consult your closed dealer. Always unplug the monitor before cleaning it. Clean the cabinet with a clean, dry cloth. Apply non-ammonia based cleaner onto the cloth, not directly onto the class screen. Do not place heavy objects on the monitor or power cord.

PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety visual inspections and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Before replacing any of these components read the parts list in this manual carefully. The use of substitute replacement parts, which do not have the same safety characteristics as specified in the parts list, may create shock, fire, or other hazards. When replacing parts or circuit boards, clamp the lead wires around terminals before soldering. Keep wires away from high voltage, high temperature components and sharp edges. Adjustment of this product please refers to the user' manual.

3.1 Switching Mode Power Supply
Service Manual
3.1.1 AC Current Input Circuit P801 is a connector for connecting AC Power. F801 is a fuse to protect all the circuit. AC input voltage is from 90v to 264V. R820 and R821 joined between two inputting main circuit to prevent man from shock. L801 is used to clear up low frequency wave. C801 and C806 are used to discharge the waves that L801 produced. High frequency waves are damped by C801 and C806. D801 is a rectifier which composed of 4 build-in diodes, it inverts AC to DC. 3.1.2 High Voltage to Low Voltage Control Circuit C805 is used to smooth the wave from rectifier. IC802 is a highly integrated PWM controller which build-in power MOSFET. When rectified DC high voltage is applied to the DRAIN pin during start-up, the MOSFET is initially off, and the CONTROL pin capacitor is charged through a switched high voltage current source connected internally between the DRAIN and CONTROL pins. When the CONTROL pin voltage Vc reaches approximately 5.8V, the control circuitry is activated and the soft-start begins. The soft-start circuit gradually increases the duty cycle of the MOSFET from zero to the maximum value over approximately 10ms. If no external feedback/supply current is fed into the CONTROL pin by the end of the soft-start, the high voltage current source is turned off and the CONTROL pin will start discharging in response to the supply current drawn by the control circuitry. Resistor R803, R807, R824 and R825 are for line over voltage shutdown(OV) and line under-voltage detection(UV). Resistors R801, R805, R822, R823 are for external current limit adjustment. And used to reduce the current limit externally to a value close to the operating peak current of primary about 1.35A. The mean is power will protected when the primary current over about 1.35A. When PWM is turned off, the main current flow will be consumed through D804, and ZD802, This will prevent MOSFET which built-in IC802 from being damaged under large current impulse and voltage spike. D806 and C815 to provide internal Auxiliary current to CONTROL pin during normal operation. Otherwise, error amplifier and feedback current input the CONTROL pin for duty cycle control. 3.1.3 DC_5V and DC_14V Output Circuit For DC 5V, D805 is used to rectify the inducted current. R806 and C811 are used to store energy when current is reversed. The parts including C814, C814, C822, C821, B801 and L803 are used to smooth the current waves. For DC 14V, D803 is used to rectify the inducted current. R802 and C802 are used to store energy when current is reversed. The parts including C808, C810 and L802 are used to smooth the current waves. 3.1.4 Feedback and OVP Protect Circuit Pin R of IC803 is supplied 2.5-v stable voltage. It connects to 5V and 14V output through R811, R810 and R818. R811, R810 and R818 are output sampling resistor. When the sampling voltage more than 2.5V or less than 2.5V, current of FB IC802 will change, this can change the voltage from T801. For 5VDC output OVP, ZD803 is a Zener Diode, when 5 voltage up to 5.6V, the zener current cause R819 voltage to ground is up to 0.7V, Q801 being triggered and OVP working. For 14VDC output OVP, ZD804 is a Zener Diode, when 14 voltage up to 18V, the Zener current cause R819 voltage to groung is up to 0.7V, Q801 being triggered and OVP working. The current of potential is used to make build-in diode light. Current of FB to IC802 will be changed, this can change the voltage from T801. Q802, R827, R828 and ZD801 make up of dummy loading circuit. For start-up sequence, during 5V output take place high loading first, this dummy loading circuit operated to insure 14V not be increased. 3.2 I/F Board Circuit 3.2.1 RGB CAPTURE - Signal RED,GREEN,BLUE input through CN103 #1,#2,#3, Stop DC via C112, C114 and C116, and then enter into U105 (TSUM56AL) analog input terminal #18,#20,#23, and then

14VDC provides the power for IC501; the control signals Brightness and ON/OFF come from I/F board. ON/OFF signal connect to pin8 of IC501 and makes IC501 enable. Brightness signal connect to pin7 of IC501 and regulates the panel brightness, R526, D515, R529, C505 make up a network of delaying time circuit and R523, R524 make up a divided voltage network, C504 is used to dump noise. The operation frequency is determined by the external Resistor R522 and capacitor C529 connected to pin5 of IC501. BURST MODE dimming pulse frequency and duty is regulated by I/F board. C503 is used for soft start and compensation, C502, C528 are used for dump noise. The output drives, include NDR4, NDRV2, PDRV3, PDRV1 (pins1, 3, 15, 16 respectively) output square pulses to drive MOSFET U501, U502, and each of U501, U502 is consist of a N channel MOSFET and a P channel MOSFET. U501 and U502 work as full-bridge topology, it is high efficient, zero voltage switching. During start up, VSEN (pin9) senses the voltage at the transformer secondary. When VSEN reaches 3.0V, the output voltage is regulated. If no current is sensed approximately 1.5 seconds IC501 shunt off. The current flowing through CCFL is sensed and regulated through sense resistor R509, R511. The feedback voltage through R506, R507, C508 connected to Pin11 (ISEN), then compared with a reference voltage (1.5V) via a current amplifier, resulting in PWM drive outputs to full-bridge switches. 4.2 Protection circuit Over Voltage Protection: R501and R502 are connected in high voltage output connector, the divided AC voltage is inverted DC voltage through D508, R505 and C507are used to rectify wave & dump noise. Then the voltage signal reaches Pin9 VSEN of IC501, when the voltage changes, build-in PWM of IC501 will adjust output voltage. Open Lamp Protection: In normal operation, the resistors R510, R511, R512, R509 are sensed a high level AC voltage, the AC signal OP1 invert DC voltage through D509, R515, C533, and the high level DC voltage reaches the gate pin of Q502, similarly, the gate pin of Q503, Q504, Q505 has high level DC voltage. So the gate pin of Q501 has a low level voltage, and the IC501 is normal operation. Once one of signal OP1, OP2, OP3, and OP4 is low, the voltages of Q501 gate pin is high level, and make the voltage of ISEN low level, the IC501 will be shunt down.
