Introduction: The Q7C3 (FP756) is a 17” SXGA (1280x1024) , 262 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. Q7C3 (FP756) also offer DDC2 function to meet VESA standard. II. Block diagram The Q7C3 (FP756) 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. III. Circuit operation theory: A.) HEAD: A-1.) Interface board diagram: 1 Q7C3 LCD Monitor Service Guide Circuit Operation Theory (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 2 Q7C3 LCD Monitor Service Guide Circuit Operation Theory 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 24C16 to store all the adjustable data and user settings. 4.) FLASH ROM: To stored the source code which is accessed by MCU to run program. A-2.)

(See Fig.3) Fig. 3 4 Q7C3 LCD Monitor Service Guide Circuit Operation Theory #3 Switching element and Isolation power transformer When the Q601 turns on, energy is stored in the transformer. During Q601 turn-off period, the stored energy is delivered to the secondary of transformer. R607, C607 and D601 is a snubber circuit. R615 is current sense resistor to control output power. (See Fig.4) Fig. 4 #4 Rectifier and filter D701 and C703 are to produce DC output. L701 and C704 are to suppress high Frequency switching spikes. (See Fig.5) Fig. 5 5 Q7C3 LCD Monitor Service Guide Circuit Operation Theory #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.

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. 12 5 4 3 2 1 D D Screw Holes Optical Points C 5 9 5 4 8 4 8 3 7 3 2 6 2 1 9 1 5 1 1 GND 9 5 4 8 4 8 7 3 7 3 7 6 2 6 2 6 H1 H2 H3 H4 HOLE-V8 HOLE-V8 HOLE-V8 HOLE-V8 GND GND GND_SIGNAL OP1 OP 9 OP2 OP OP3 OP OP4 OP OP5 OP OP6 OP OP7 OP C OP8 OP OP9 OP OP10 OP OP11 OP OP12 OP OP13 OP OP14 OP GND B B Benq Corporation Project Code Model Name OEM/ODM Model Name Q7C3-LG 99.L9072.001 NA Title A A INTERFACE BOARD Size PCB P/N <Size> 48.L9001.S21 PCB Rev.
