WARNING FOR THE SAFETY-RELATED COMPONENT.

• There are some special components used in LCD
monitor that are important for safety. These parts are
marked on the schematic diagram and the
replacement parts list. It is essential that these critical
parts should be replaced with the manufacturer’s
specified parts to prevent electric shock, fire or other
hazard.

• Do not modify original design without obtaining written
permission from Gateway2000 Inc. or you will void the
original parts and labor guarantee.

TAKE CARE DURING HANDLING THE LCD MODULE
WITH BACKLIGHT UNIT.

• Must mount the module using mounting holes arranged
in four corners.

• Do not press on the panel, edge of the frame strongly
or electric shock as this will result in damage to the
screen.

• Do not scratch or press on the panel with any sharp
objects, such as pencil or pen as this may result in
damage to the panel.

• Protect the module from the ESD as it may damage the
electronic circuit (C-MOS).

• Make certain that treatment person’s body are
grounded through wrist band.

• Do not leave the module in high temperature and in
areas of high humidity for a long time.

• The module not be exposed to the direct sunlight.

• Avoid contact with water as it may a short circuit within

the module.

• If the surface of panel become dirty, please wipe it off
with a softmaterial. (Cleaning with a dirty or rough cloth
may damage the panel.)

WARNING

BE CAREFUL ELECTRIC SHOCK !

• If you want to replace with the new backlight (CCFL) or
inverter circuit, must turn off the power button or
disconnect the AC adapter because high voltage
appears at inverter circuit about 650Vrms.

• Handle with care wires or connectors of the inverter
circuit. If the wires are pressed cause short and may
burn or take fire.

PRECAUTION

CAUTION

Please use only a plastic screwdriver to protect yourself
from shock hazard during service operation.

CAUTION

• There is two backlight, must distinguish between
the top (upper) and the bottom (lower), and be
careful of treatment it.

• MTBF (Mean Time Between Failure) of a backlight
is about 10,000 hours.

System Block Diagram

Block Diagram for Main Logic Board

1.DC/DC Converter

This curcuit supplies stand-by 5V(+5Vst) and regular
5V(+5V) for using MAX785 from AC/DC adapter(+24V).
The +5V voltage supply to power swichng IC(SI4925)
and 3.3V voltage regulator.
The state of power down makes all voltage except
+5Vst down using SHDN pin from system controller
(68HC05BD1).

2. System Controller

This curcuit consists of two EEPROM IC(24C02)
which stores the control data for system and
communicates
DDC(Display Data Channel) and oscillator(X201).
The operating procedures of system controller and its
associated circuit are as follows:

1) The system controller detects frequency of vertical
sync through DFP(Digital Flat Panel) 20 pin
connector.

This controller controls the power swiching
IC(SI4925) by the detection of verticalsync(HVsync).

2) The system controller controls the brightness of
inverter by using the key control button and store
the data to EEPROM(24C02).

3. Power Swiching Circuit

This block supplies +24V(+24Vin) to the inverter for
the backlight voltage of the LCD module and +5V
(+5Vmod) for data control of the LCD module.

4. Signal Transmission

The digital video signals(R,G,B) and clock signals(CLK)
by differencial signals(Tx0,Tx1,Tx2,Txc), are transmitted
to LCD module through EMI filter from PC system which
has digital video card.

PIN NAME FUNCTION

1 CS3 Current-sense input for +3.3V; +100mV = current limit level referenced to FB3.
2 SS3 Soft-start input for +3.3V. Ramp time to full current limit is 1ms/nF of capacitance to GND.
3 ON3 ON/

OFF

control input disables the +3.3V PWM. Tie directly to VL for automatic start-up.
4 D1 #1 level-translator/comparator noninverting input, threshold = +1.650V. Controls Q1. Tie to GND if unused.
5 D2 #2 level-translator/comparator noninverting input (see D1)
6 VH External positive supply-voltage input for the level translators/comparators

7Q2

#2 level-translator/comparator output. Sources 20µA from VH when D2 is high. Sinks 500µA to GND

when D2 is low, even with VH = 0V.
8 Q1 #1 level translator/comparator output (see Q2)
9 GND Low-current analog ground

10 REF 3.3V reference output. Sources up to 5mA for external loads. Bypass to GND with 1µF/mA of load or

0.22µF minimum.

11 SYNC

Oscillator control/synchronization input. Connect to VL or GND for 200kHz; connect to REF for

300kHz. For external clock synchronization in the 240kHz to 350kHz range, a high-to-low transition

causes a new cycle to start.

12

SHDN

Shutdown control input, active low. Tie to VL for automatic start-up. The 5V VL supply stays active in

shutdown, but all other circuitry is disabled. Do not force

SHDN

higher than VL + 0.3V.

13 ON5 ON/

OFF

control input disables the +5V PWM supply. Tie to VL for automatic start-up.
14 SS5 Soft-start control input for +5V. Ramp time to full current limit is 1ms/nF of capacitance to GND.
15 CS5 Current-sense input for +5V; +100mV = current-limit level referenced to FB5.
16 DH5 Gate-drive output for the +5V high-side MOSFET
17 LX5 Inductor connection for the +5V supply
18 BST5 Boost capacitor connection for the +5V supply (0.1µF)
19 DL5 Gate-drive output for the +5V low-side MOSFET
20 PGND Power ground
21 FB5 Feedback and current-sense input for the +5V PWM
22 VL 5V logic supply voltage for internal circuitry. VL is always on and can source 5mA for external loads.
23 V+ Supply voltage input from battery, 5.5V to 30V
24 DL3 Gate-drive output for the +3.3V low-side MOSFET
25 BST3 Boost capacitor connection for the +3.3V supply (0.1µF)
26 LX3 Inductor connection for the +3.3V supply
27 DH3 Gate-drive output for the +3.3V high-side MOSFET
28 FB3 Feedback and current-sense input for the +5V PWM
