Setup input timing ICL-605, 32-Grays pattern. Setup unit and keep it warm up at least 30 minutes. B. Timing adjustment: 1. Enter factory setting area (press "LEFT", "EXIT" and then press "SOFTPOWER"). 2. Check the settings to following values: Contrast = 50 Brightness = 90 Volume = 30 OSD time = 20 Color = sRGB Language = English Then, turn off the monitor power. 3. Turn on power enter user area. C. Color balance adjustment: 1. Enter factory setting area (press "LEFT", "EXIT" and then press "SOFTPOWER"). 2. Setup input timing UVGA7, 4-Grays pattern. 3. Press "AUTO", waiting for press | ||

File name Q7C3-circuit operation theory.pdf Q7C3 LCD Monitor Service Guide Circuit Operation Theory I. 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). BD. The block diagram is shown as below. 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 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.)
