SAFETY PRECAUTIONS
1. CAUTION:
No modification of any circuit should be attempted.
Service work should only be performed after you
are throughly familiar with all of the following safety
checks and servicing guide lines.
2. SAFETY CHECK
Care should be taken while servicing this LCD
display.
Because of the high voltage used in the
inverter circuit. These voltage are exposed in such
areas as the associated transfomer circuits.
3. POWER SUPPLY REQUIREMENTS
The external powr converter for this display
utilizes AC and DC cords , AC cord is
detachable , but DC cord is permanently
attached . Any attempt to replace another
adapter could result in serious problem on the
display.
4-6 Voltage measured must not exceed 1.5 volt
RMS, from any exposed metallic part to the
ground. A leakage current tester may be
used in the above hot check, in which case
any circuit measured must not exceed 1.0
miliamp. In the case of a measurement
exceeding the 1.0 miliamp value, a rework is
required to eliminate the chance of a shock
hazard.

4. LEAKAGE CURRENT HOT CHECK
4-1 Plug the AC cord directly into the AC outlet.
Do not use an isolation transformer during this
check.
4-2 Connect a
1500 ohm , 10 watt resistor ,
paralleled by a 0.15uF capacitor between each
metallic part and a good earth ground.
4-3 Use an AC voltmeter with 1000 ohm / volt or
more sensitivity and measure the AC voltage
across the combination 1500 ohm resistor
and 0.15uF capacitor.
4-4 Move the resistor connection to each exposed
metallic part and measure the voltage.
4-5 Reverse the polarity of the AC plug in the AC
outlet and repeat the above measurement.

high-speed triple-ADC , PLL, high sacling engine, OSD controller and on-chip microcontroller.
a) Clock Generation :
Crystal Input Clock (TCLK and XTAL). This is the input pair to an internal crystal oscillator and
corresponding logic. A 14.318 MHz crystal is recommended.
b) Hardware Reset ( Pin 5 )
Hardware Reset signal is generated by MAX6326 (U10).It assert a reset signal at least 100 ms.
c) Analog to Digital Converter
The gm2120 chip has three ADC's (analog-to-digital converters), one for each color (red, green and blue)
The analog RGB signals are connected to gm2120 as described below

d) OSD :
The gm2120 has a fully programmable ,high-quality OSD controller.The on-chip static RAM(4096 words
by 24 bits) stores the cell map and the cell definitions.
e) On-Chip Microcontroller (OCM)
The gm2120 on-chip microcontroller(OCM) serves as the system microcontroller.That is , it programs the
gm2120 and manages other devices in the
system such as the keypad, the backlight, LED, audio and
non-volatile RAM.using general purpose input/output (GPIO) pins.

f) Panel Power Sequencing ( PPWR, PBIAS) ( Pin 113~114)
20 has two dedicated outputs PPWR and PBIAS ( Pin113 and Pin114) to control LCD power
sequencing once data and control signals are stable.
g) Parallel ROM Interface Port (Pin 8~25, Pin28~35)
The gm2120 has parallel ROM interface port , pin8~25 for address bus, pin28~35 for data bus.
h) Panel interface (Pin 55~66, Pin69~80, Pin83~87, Pin90~96.Pin99~110)
The gm2120 driver interface is highly programmable. It supports dual bus / dual port for SXGA drivers.
4.1.2 LVDS Transmitter DS90C383 (U1,U2)
The DS90C383 transmitter converts 28 bits of TTL data into four LVDS ( Low Voltage Differential
Signaling) data streams. A phase-locked transmit clock is transmitted in parallel with the data streams
over a fifth LVDS link. At a transmit clock frequency of 85 MHz, 24 bits of RGB data and 3 bits of LCD
timing and control data ( FPLINE, FPFRAME, DRDY) are transmitted at rate of 595 Mbps per LVDS
data channel. U1 AS the ODD pixel transmitter , U2 as the EVEN pixel transmitter.
L7EA (AL708)

4.1.3 Power Regulator AIC1563 (U12),LT1117 (U5, U6)
The AIC1563 is a monolithic control IC containing the primary functions required for DC to DC converters.
The device consists of an internal temperature compensated reference, conparator, controlled duty cycle
oscillator with an active current sense circuit. Desired output voltage are determined by the equation
Vout = 1.25 ( 1 + R104 / R103), In this case, the output voltage are 5 Volts.
The AIC1117 is a low dropout positive adjustable regulator with minumum of 1A output current capability.
So it is well suited for 3.3 V and 2.5 V Rregulator.
U6 as a 2.5 V regulator , Desired output voltage are determined by the equation
Vout=5 x ( R53 / R53+R56)= 2.5
U5 as a 3.3 V regulator , Desired output voltage are determined by the equation
Vout=5 x ( R30 / R30+R36)= 3.3
4.2 Audio Board AN7522 (U1)
The AN7522 is a 2 channel audio power amplifier capable of delivering 2W of continuous average power
to an 8 ohms with less than 0.5% (THD) from a 12 V power supply.
An7522 can directly drive 8 ohms speaker , does not require output coupling capacitor, bootstrap capacitor
,or snubber network. Audio line-in are feed into pin 6,8 of the AN7522. The output power is controlled by
the DC voltage of pin 8 from gm2120 GPIO port.
