PRECAUTION
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 IBM 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).
WARNING
BE CAREFUL ELECTRIC SHOCK !
• If you want to replace with the new backlight (CCFL) or
inverter circuit, must 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.
CAUTION
IF BRIGHTNESS OF THE LCD MODULE DARKEN,
REPLACE THE BACKLIGHT ONE OR ALL.
• 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 25,000 hours.
Top (Upper) Backlight Ass’y
(P/N: 6913TZZ001D)
• 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.)
CAUTION
Please use only a plastic screwdriver to protect yourself
from shock hazard during service operation.

DESCRIPTION OF BLOCK DIAGRAM
1. Video Amp & PLL & A/D Converter Circuit
AD9884(U5) is one chip IC which it supports three function block of Video Amp, PLL and A/D converter.
Video signal (0.7Vp.p) clamped through C63, 64, 65 inputs to U5’s R, G, and B pins. The signal level is 0.7Vac added
4Vdc. This signal is processed as a proper 8 bit digital signal for input of MX88L281 (U1) by U5’s amplifying, phase
locking, and A/D converting operation.
U5 generates clock and horizontal sync for MX88L281 (U1) with MC14066B(U11)’s output horizontal sync signal.
Sync Process (U14)’s clamp output makes U5 keep video signal’s voltage from zero to AC signal’s minimum level
constantly regardless of various input video signals.
2. Macronix Circuit (Scaler chip)
The MX88L281 (U1) gets the video signal converted analog to digital from U18, and carries out four function of image
processing that interpolates input signal less than 1024x768 resolution to that of 1024x768 resolution, displays one to
one image without interpolation, mixes OSD(On Screen Display) signal by interfacing with OSD IC (U2), and controls
three memories(U6, 7, 8) as frame converter.
U1 outputs signals of HSYNC-OUT, VSYNC-OUT, DEN, CLKA-ODD, and each 8 bit R, G, B to transmitter IC (U16).
3. Memory Circuit
2M byte SDRAM(U6, 7 , 8) is used as a frame converter for supporting up to 85 Hz frame rate and controlled by
MX88L281(U1).
The control signals are CKA, CLK, UDOM, LDOM, /WE, /CAS, /RAS, /CS, /BA.
4. Panel-Link Circuit
Panel link transmitter (U16) delivers digital signal to the receiver inside LCD module by method of abstraction.
The abstracted signals are pairs of TX0+-, TX1+-, TX2+-, TXC+- of which voltage swing is 0.5V each.
Its swing is similar to LVDS (Low Voltage Differential Signal).
Transmitter (U16) gets signals of HSYNC-OUT, VSYNC-OUT, DEN, CLKA-ODD from U4, and outputs LVDS
through TX pin. When PD pin’s input is low, transmitter goes to power down mode.
5. System Controller (Microprocessor) Circuit
1) Microprocessor (U4) distinguishes polarity and frequency by calculating horizontal and vertical sync input from
signal source.
2) Microprocessor (U4) carries out power control by sending power-down trigger signal to each IC.
U1, U5, and U16 has PD(Power-down) pin which operates at active-low each.
3) Microprocessor (U4) communicates with EEPROM (U10), AD9884 (U5), MX88L281 (U1), and OSD IC (U2)
through SCL and SDA or 8 bit bus line. It makes all devices with communication channel operated properly.
4) Microprocessor (U4) let User adjust screen by each OSD function.
6. DC/ DC Converter
This circuit supplies DC power for each device needing DC voltage of 3.3VD, 3.3VD1, 3.3VA, PVD_ADC, 5VA and
5VSTD.
LM2674(U13)and LM2596(U15) , the DC/DC controller IC converts input 24Vdc into each voltage to be needed with
peripheral circuit composed of Choke Coil (L8, 9), condensing components (ZD5, ZD6) and Regulators
(U22, 19, 20,2 3, 24).
5VSTD is supplied for Microprocessor through regulators (U22).
MODPWR for LCD module power are supplied by switching FET(U12) and regulator(U16), controlled by
Microprocessor’s triggering signal (M-PWR ON).
