! Do not place heavy objects on the monitor or power cord.
1.2. 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 voltages, 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.
1.3. SERVICE NOTES
1. When replacing parts or circuit boards, clamp the lead wires around terminals before
soldering.
2. When replacing a high wattage resistor (more than 1W of metal oxide film resistor) in circuit
board, keep the resistor about 5mm away from circuit board.
3. Keep wires away from high voltage, high temperature components and sharp edges.
4. Keep wires in their original position so as to reduce interference.
5. Usage of this product please refer to also user's manual.

7. WORKING THEOREM
A. Scaling controller
The ADC is to convert RGB analog signal to digital signal that scaling chip can acknowledge.
The HSYNC input receives a logic signal and provides the frequency reference for pixel clock
generation.
The scaling IC is to converts the input signal ranging from VGA to SXGA into SXGA resolution
that panel can acknowledge.
GENERAL DESCRIPTION
The MST8116A is a high performance, and fully integrated graphics processing IC solution for
LCD monitors with resolutions up to SXGA. It is configured with an integrated triple-ADC/PLL, a
high quality scaling engine, an on-screen display controller, a built-in output clock generator, a
panel timing controller (TCON), and RSDS display interface. To further reduce system costs, the
MST8116A also integrates intelligent power management control capability for green-mode
requirements and spread-spectrum support for EMI management.

B. MTV312M64
The MTV312M micro-controller is an 8051 CPU core embedded device especially tailored for CRT/LCD
Monitor applications. It includes an 8051 CPU core, 1024-byte SRAM, 14 built-in PWM DACs, VESA DDC interface,
4-channel A/D converter, and a 64K-byte internal program Flash-ROM.
A “CMOS output pin” means it can sink and drive at least 4mA current. It is not recommended to use such
pin as input function.
A “open drain pin” means it can sink at least 4mA current but only drive 10~20uA to VDD. It can be used as input or
output function and needs an external pull up resistor.
A “8051 standard pin” is a pseudo open drain pin. It can sink at least 4mA current when output is at low level, and drives at
least 4mA current for 160nS when output transits from low to high, then keeps driving at 100uA to maintain the pin at high
level. It can be used as input or output function. It needs an external pull up resistor when driving heavy load device.
POWER CONFIGURATION
The MTV312M can work on 5V or 3.3V power supply system.
In 5V power system, the VDD pin is connected to 5V power and the VDD3 needs an external capacitor, all
output pins can swing from 0~5V, input pins can accept 0~5V input range.
And ADC conversion range is 5V. However, X1 and X2 pins must be kept below 3.3V.
In 3.3V power system, the VDD and VDD3 are connected to 3.3V power, all output pins swing from 0~3.3V, HSYNC,
VSYNC and open drain pin can accept 0~5V input range, other pins must be kept below 3.3V. And the ADC conversion
range is 3.3V.
C. INVERTER
In order to drive the CCFLs embedded in the panel module, there is a half bridge inverter to convert by the controller.
The input 12V up to hundreds of AC voltage output.
The inverter is formed by symmetric in order to drive the separate lamp modules.
The input stage consists of a PWM controller, half bridge inverter, and switching MOSFET to convert DC input into AC
output.
The output stage consists of a tuning capacitor, coupling capacitor, transformer, push-pull MOSFET pair to boost AC
output up to hundreds of voltage.
And one resister is serial to lamp for output voltage feedback.
There are two signal to control the inverter which come from system.
Logic “high” level which send to I901 is turn on the inverter.
BRI signal control brightness by DC level which was integral from PWM signal.
