Chapter 1- PRECAUTIONS & SAFETY NOTICES

1. SAFETY PRECAUTIONS

This monitor is manufactured and tested on a ground principle that a users 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 rearof the monitor. If youre 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 electricshock 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. Applynon-ammonia based cleaner onto the cloth, not directly onto the class screen.

Do not place heavy objects on the monitor or power cord.

2. 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 thismanual 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.

3. SERVICE NOTES

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.

Keep wires in their original position so as to reduce interference.

Adjustment of this product please refers to the user manual.

CHAPTER 3-CIRCUIT THEORY

1. Monitor Block DiagramThe LCD Monitor contains an interface board, and inverter/power/Audio board, keypad board and flat panel.In Inverter/power/Audio board, power section supplies +14V & +5V for Inverter/Audio and Interface board

used. The inverter section drives the backlight of panel and the DC-DC conversion. The Audio section

drives speaker (2 x1W).

3. Electronic Circuit Theory

3.1 Switching Mode Power Supply

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 inputvoltage is from 90v to 264V. SW801 is hard switch for control AC input.

C867/C802/C832/C866 are safety Y capacitors. C803/C804 are safety X capacitors. R801

R802 and R803 joined between two inputting main circuit to discharge electric energy of C804

when power AC off. L801/L802 are used to clear up low frequency wave. High frequency

waves are damped by C867 and C802. D801 is a rectifier build-in 4 diodes. It Transform AC to

DC.

3.1.2 Power Factor Controller CircuitThis circuit is typical boost model PWM power to improve power factor. T801 is inductor to

storage electric energy. T801 store energy when Q801 switch on. And T801 discharge energy

when Q801 switched off. R804R805R806R808ZD802R807R822 and Q802 control

PFC output DC voltage. PFC output voltage is 400V when AC input is 180V~240V. Output

voltage is 280V when AC input is 100~160V. R817R818R819 and R821 control PFC out

stabilization. The pin function of IC801 can find from component datasheet.

3.1.3 High DC Voltage to Low Voltage (5V) Control CircuitIC805 is this DC-DC circuit PWM controller. When pin6 of IC805 be charged to 12V, IC803

start drive Q805 to transform high DC voltage to low DC voltage 5V.D812R865Q806

D814C836 and C837 provide auxiliary power for IC803 normal operation. R862 and R861

sample from auxiliary winding to control over voltage protection for DC 5V output. R873 and

R872 sample DC 5V output voltage to compare voltage level with reference voltage of IC807.

The signal get from compared result via IC806 feed back to pin2 of IC805. Then control PWM

duty to control DC output stabilization. T803 is transformer. D815 is rectifier for DC 5V output.

C843 and C844 are filter for DC 5V.

3.1.4 High DC Voltage to Low Voltage (24V) Control Circuit

This circuit same section 3.1.3. IC802 is this DC-DC circuit PWM controller. When pin6 of

IC802 be charged to 12V, IC802 start drive Q803 to transform high DC voltage to low DC

voltage 24V.D806Q804C818 and C815 provide auxiliary power for IC802 normal operation.

R832 and R831 sample from auxiliary winding to control over voltage protection for DC 24V

output. R843R851 and R842 sample DC 24V output voltage to compare voltage level with

reference voltage of IC804. The signal get from compared result via IC803 feed back to pin2 ofIC802. Then control PWM duty to control DC output stabilization. T802 is transformer. D807

and D810 are rectifiers for DC 24V output. C825 and C826 are filter for DC 24V.

3.1.5 DC_24V Transform to DC 12V Circuit

IC808 is this DC-DC circuit PWM controller. R883 is for output short protection. C854 adjust
