10/9 '03R1:10K --> 2K.
PC5V 3.3_MCU PC5V_OFF + - H + + L - + Don't care
If both PC5V and 3.3_MCU exist:PC5V_OFF should set "LOW" to prevent PC5V from enteringthe system.When only PC5V exists:PC5V_OFF should set "HIGH" to provide CPU power.Actually, in the initial state, NO PC5V_OFF, if VGAcable is connected, PC5V exists --> Q4 will ON.That will make 3.3_M = 3.3V.

I. Introduction: The Q7T3-CPT is a 17” SXGA (1280x1024) , 26.2 K colors(R, G, B 6-bit data) TFT LCD
monitor without multi-media function. It’s an analog interface LCD monitor with a 15 pins D-sub signal cable and it’s compliant with VESA specification to offer a smart power management and power saving function. It also offers OSD menu for users to control the adjustable items and get some information about this monitor, and the best function is to offer users an easy method to set all adjustable items well just by pressing one key, we called it “Auto key” which can auto adjusting all controlled items. Q7T3-CPT also offer DDC2 function to meet VESA standard.
II. Block diagram
The Q7T3-CPT consists of a head and a stand (base). The head consists of a LCD module with 4 lamps, a power board (include AC/DC, DC/DC and inverter board), a control board and interface BD. The block diagram is shown as below.

(a) Circuit operation theory: A basic operation theory for this interface board is to convert analog signals of Red, Green, Blue. The scaling IC has internal A/D converter, internal OSD and auto detect input timing functions. A/D converter is convert analog signal to digital data. OSD is offering adjustable functions to end-user. Detect timing is for detect change mode. Scalar finally output the digital RGB data, the Hsync, Vsync and pixel clock to LCD panel driver IC by RSDS interface. MCU also embedded in PW133A controls system processing. EEPROM is stored DDC data, OSD common data and user mode data. Flash-Rom is stored the source code which is accessed by MCU to run program.
(b) IC introduction: 1.) DDC (Display Data Channel) function: We use DDC IC to support DDC/2B function. DDC data
is stored in 24C02(EEPROM). Those data related to LCD monitor specification. PC can read them by “SDA” and “SCL” serial communication for I²C communication for DDC2B.
2.) PW133A IC : There are A/D, Scaling, OSD, MCU functions in the PW133A IC. Scaling IC is revolutionary scaling engine, capable of expanding any source resolution to a highly uniform and sharp image, combined with the critically proven integrated 8 bit triple-ADC and patented Rapid-lock digital clock recovery system. It also support detect mode and DPMS control. MCU

#5 PWM Controller The PWM controller NCP1200A implements a standard current mode architecture. With an internal structure operating at a fixed 40KHz. Where the switch time is dictated by the peak current set-point. When the current set-point falls below a given value. The output power demand diminishes, the IC automatically enters the so-called skip cycle mode and provides excellent efficiency.
Fig. 6
#6 Feedback circuit PC123 is a photo-coupler and TL431 is a shunt regulation. They are used to detect the output voltage change and be the primary and secondary isolation. When output voltage changes, the feedback voltage will be compared and duty cycle will be decided to control the correct output voltage. (See Fig.7)

3.3 Oscillator Circuit
Royer circuit uses the characteristic of transformer saturation to oscillate. When the DC power inject, Q759 or Q760 will turns on, and the current Ic increases. After a period, the transistor will leave the saturation status and Vce increase. The result causes the voltage of primary coil get lower. Finally the transistor turn off, and another transistor turn on. These statuses are repeated and the pin7 and pin8 of T751 will get a Sin Wave to turn on CCFL.

I. Introduction: The Q7T3-FP767 is a 17” SXGA (1280x1024) , 262 K colors(R, G, B 6-bit data) TFT LCD
monitor with multi-media function. It’s an analog interface LCD monitor with a 15 pins D-sub signal cable and it’s compliant with VESA specification to offer a smart power management and power saving function. It also offers OSD menu for users to control the adjustable items and get some information about this monitor, and the best function is to offer users an easy method to set all adjustable items well just by pressing one key, we called it “Auto key” which can auto adjusting all controlled items. Q7T3-FP767 also offer DDC2 function to meet VESA standard.
II. Block diagram
The Q7T3-FP767S consists of a head and a stand (base). The head consists of a LCD module with 4 lamps, a power board (include AC/DC, DC/DC and inverter board), a control board and interface BD. The block diagram is shown as below.

(a) Circuit operation theory: A basic operation theory for this interface board is to convert analog signals of Red, Green, Blue. The scaling IC has internal A/D converter, internal OSD and auto detect input timing functions. A/D converter is convert analog signal to digital data. OSD is offering adjustable functions to end-user. Detect timing is for detect change mode. Scaler generate the pixel clock to the LVDS transmitter. Finally output the digital RGB data, the Hsync, Vsync and pixel clock to LCD panel driver IC by LVDS transmitter. MCU also embedded in Gm2120 offers H/W DDC2Bi function & controls system processing. EEPROM is stored DDC data, OSD common data and user mode data. Flash-Rom is stored the source code which is accessed by MCU to run program.
(b) IC introduction: 1.) DDC (Display Data Channel) function: We use DDC IC to support DDC/2B function. DDC data
is stored in 24C02(EEPROM). Those data related to LCD monitor specification. PC can read them by “SDA” and “SCL” serial communication for I²C communication for DDC2B.
2.) Gm2120 IC: There are A/D, Scaling, OSD, MCU functions in the Gm2120 IC. Scaling IC is revolutionary scaling engine, capable of expanding any source resolution to a highly uniform and sharp image, combined with the critically proven integrated 8 bit triple-ADC and patented

#5 PWM Controller The current mode control IC UC3842B is used to control PWM. When the VCC terminal of it gets 16V, IC601 turns on. +5V will be set up at Pin8 through soft start circuit, which includes R617, C611, D606 and D605. R616 and C610 generate a fixed frequency saw-tooth wave at Pin4.
Fig. 6
#6 Feedback circuit PC123 is a photo-coupler and TL431 is a shunt regulation. They are used to detect the output voltage change and be the primary and secondary isolation. When output voltage changes, the feedback voltage will be compared and duty cycle will be decided to control the correct output voltage. (See Fig.7)
Fig. 7
A-3.) Control board introduction: The main parts of the control board are a push button, and a LED.
(a) Push button: It’s a simple switch function, pressing it for “ON” to do the auto adjustment function, releasing it for “OFF” to do nothing. (c) LED: It indicates the DPMS status of this LCD monitor; green light means DPMS on (Normal operating condition). Amber light means DPMS off (Power off condition).

3.3 Oscillator Circuit
Royer circuit uses the characteristic of transformer saturation to oscillate. When the DC power inject, Q759 or Q760 will turns on, and the current Ic increases. After a period, the transistor will leave the saturation status and Vce increase. The result causes the voltage of primary coil get lower. Finally the transistor turn off, and another transistor turn on. These statuses are repeated and the pin7 and pin8 of T751 will get a Sin Wave to turn on CCFL.

“Power” buttons at the same time. A “Factory” word will be showed on the upper left hand side of OSD Main menu.) Burn in mode have already started. (See Fig 1.). If it hasn’t started, Please choose “BURN IN MODE” tag and select “On” to enable burn-in mode.
3. Setup unit and keep it warm up at least 30 minutes
B. Timing adjustment:
1. Enter factory setting area (if it isn’t at factory mode, Please press “Menu” and “Exit” plus “Power” buttons at the same time to enter factory mode.).
2. Burn-In Mode “off”. See Fig 2. 3. Select timing from Table 1. The timing marked with star sign (*) have to be adjusted. 4. Execute “Recall All” (press “Yes”) to clear user area in EEPROM 5. The cursor moves to “AUTO Adjust ” or press “I-Key” to run “AUTO adjustment” function. 6. Check the phase of the image; if phase is not perfect adjust it to the best condition. 7. Adjust the settings to following values:
CONTRAST = 50 BRIGHTNESS = 90 OSD TIME = 20 COLOR = sRGB
8. When Factory mode is disable (burn-in mode “off”) then power off after power on will enter user mode.
C. Color balance adjustment: 1. Setup input timing VGA_60Hz, cross-hatch (General-1) pattern. 2. Enter factory setting area (if it isn’t at factory mode, Please press “Menu” and “Exit” plus “Power” buttons at the
same time to enter factory mode.). 3. Setup the “Burn-in mode” is “On” 4. Select the color to user-preset mode. 5. At Main menu move cursor to “AUTO Adjust ” tag then press the “ENTER” or “I-Key” to run “AUTO Color
balance” function. 6. Checking if the picture is no good, reject this monitor.
D. Color adjustment: 1. Setup input timing VGA_60Hz, cross-hatch (General-1) pattern. 2. Enter factory setting area (if it isn’t at factory mode, Please press “Menu” and “Exit” plus “Power” buttons at the
same time to enter factory mode.).
3. Move cursor into “BUR-IN MODE” tag and select “On” to enable burn-in mode. (If it wants to do “Auto Color balance”, please select the color to user-preset mode.)
4. Measure color temperature by Minolta CA-110 (or equivalent equipment). 5. The monitor has already set default value to monitor (just for 56.91L53.001)
If it can’t meet color temperature spec. upper default value. Please use Auto Alignment to calibrate the color temperature; Bluish, & Reddish and sRGB. The color temperature specification as follows:

6. Move cursor into “BURN IN MODE” tag and select “Off” to disable burn-in mode. 7. Turns off the monitor power.
E. Writing EDID file : 1. Setup a PC with DDC card.
2. Connect PC to monitor with a D-sub signal cable.
3. Please refer to the C212 for the correct EDID file.
4. Runs the writing program to write the EDID file into EEPROM for analog input, ie. 15-pin D-sub.
5. Read both EEPROM data and confirm it to match with the C212 definition.

(a) Circuit operation theory: A basic operation theory for the interface board is to convert input signal into digital RGB . Analog RGB signal is converted to digital signal through ADC. DVI-D signal is converted through TMDS receiver. The microprocessor Mst8131B receives video data and optimizes the image automatically. It also supports input source selection, 16 color from a 64k palette bitmap OSD, and keypad con t ro l l ing . The ou tpu t da ta a re sen t to LCD module .
(b) IC introduction: 1.) DDC (Display Data Channel) function: We use DDC IC to support DDC/2B function. DDC data is
stored in 24C04(EEPROM). Those data related to LCD monitor specification. PC can read them by “SDA” and “SCL” serial communication for I2C communication for DDC2B.
2.) Mst8131B IC: There are A/D, Scaling, OSD, MCU functions in the Mst8131B IC. Scaling IC is revolutionary scaling engine, capable of expanding any source resolution to a highly uniform and sharp image, combined with the critically proven integrated 8 bit triple-ADC and patented Rapid-lock digital clock recovery system. It also support detect mode and DPMS control. MCU control unit, it controls all the functions of this interface board, just like the OSD display setting, the adjustable items, adjusted data storage, the external IIC communication, support DDC2B.
3.) EEPROM: We use 24C04 to store all the adjustable data and user settings. And use 24C02 to store DVI EDID data. 4.) MTV312M64: To stored the source code which is accessed by MCU to run program.

#5 PWM Controller The PWM controller NCP1200A implements a standard current mode architecture. With an internal structure
operating at a fixed 40KHz. Where the switch time is dictated by the peak current set-point. When the current set-point falls below a given value. The output power demand diminishes, the IC automatically enters the so-called skip cycle mode and provides excellent efficiency.
Fig. 6
#6 Feedback circuit PC123 is a photo-coupler and TL431 is a shunt regulation. They are used to detect the output voltage
change and be the primary and secondary isolation. When output voltage changes, the feedback voltage will be compared and duty cycle will be decided to control the correct output voltage. (See Fig.7)

3.3 Oscillator Circuit
Royer circuit uses the characteristic of transformer saturation to oscillate. When the DC power inject, Q759 or Q760 will turns on, and the current Ic increases. After a period, the transistor will leave the saturation status and Vce increase. The result causes the voltage of primary coil get lower. Finally the transistor turn off, and another transistor turn on. These statuses are repeated and the pin7 and pin8 of T751 will get a Sin Wave to turn on CCFL.
