DV172 LCD Monitor Service Guide Circuit Operation Theory I. Introduction: DV172 model is a 17” SXGA (1280x1024) 18 bits color TFT LCD monitor with multi-media function. The features of DV172 are as below, (a)Dual signal input supported for a 15pins D-sub and a DVI-D input connectors. (b)It’s compliant with VESA DPMS spec to offer a smart power management and power saving function. (c)OSD menu supported for users to control the adjustable items and get some information about this monitor. (d)”Auto” button function supported to offer users an easy method to set all adjustable & controlled items well by just pressing one button, “Auto”. (e)VESA DDC2B function supported. (f)Audio function supported with 2 speakers.
II. Block diagram DV172 consists of a head and a stand (base). The head consists of a LCD module with 4 lamps, a power board (include AC-DC, inverter power & audio circuit), a control board and an interface board. The block diagram is shown as below. TFT-LCD module with 4 CCFL(backlight)

(a) Circuit operation theory: (The scaling IC used in DV172 is Genesis gm5120) A basic operation theory for this interface board in Analog input signals processing, the scaling IC inside A/D converter will convert analog input signals of Red, Green and Blue to 8 bits digital signals of Red, Green and Blue, and for interface board in DVI-D(TMDS) digital input signals processing, the scaling IC inside TMDS receiver will convert TMDS signals to 8 bits digital signals of Red, Green and Blue. Then no matter input signals Analog or DVI-D(TMDS) format are, they have been converted to 8 bits digital Red, Green and Blue signals, and the scaling IC inside MCU and scaling control circuit will start to do timing signal detecting and calculating to output the proper LCD panel signals to LCD panel circuit. The timing signal detecting function in the scaling IC is to detect whether input H-sync, V-sync or digital pixel clock signals’ status have been changed by host PC system, then it will do short-time picture blanking, signal processing and converting again if input signals have been changed. The scaling IC inside OSD circuit will be programmed to an OSD menu which can be showed on the screen to offer adjustable functions to end-users to control and adjust some picture settings by themselves. After the scaling IC internal signal processing is done, it will output the digital RGB data, the H-sync, V-sync, pixel clock and DE(data enable) signal to LVDS transmitter and then to LCD panel driver circuit. There are two kinds of EEPROM used in interface board, one is 24C02 which is used to store DDC 2
DV172 LCD Monitor Service Guide Circuit Operation Theory data, we also call it, DDC IC, and another is to store OSD common data and those picture controlled and data. Flash-Rom is to store the source code which will be accessed by the scaling IC inside 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”(“DSDA” & “DSCL” for DVI-D input port) serial communication for I 2C communication for DDC2B. 2.) Gm5120 IC: There are A/DC, TMDS receiver, Scaling, OSD, MCU in the gm5120 IC. Scaling IC is revolutionary scaling engine, capable of expanding any source resolution to a highly uniform and sharp image or down scaling from UXGA, 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: All the adjustable data and user settings are stored in EEPROM (24C16). 4.) FLASH ROM: To store source code which will be accessed by Scaling IC inside MCU to run program.

DV172 LCD Monitor Service Guide Circuit Operation Theory (a) EMI Filter This circuit (fig. 2) is designed to inhibit electrical and magnetic interference for meeting FCC, VDE, VCCI standard requirements.
Fig. 2 (b) Rectifier and filter AC Voltage (90-264V) is rectified and filtered by BD601, C605 (See Fig 3) and the DC Output voltage is 1.4*(AC input). (See Fig.3)
Fig. 3 (c) 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)

DV172 LCD Monitor Service Guide Circuit Operation Theory
Fig. 4 (d) 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 (e) 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.

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)

DV172 LCD Monitor Service Guide Circuit Operation Theory 3.)Circuit Operation Theorem 3.1) ON/OFF SWITCH
The turn-on voltage was controlled by R756 and R757.The inverter was turned on or off by the switching transistors Q761 and Q757, Also regulator IC751 is control by Q761 and Q757 decide supply 15V to inverter part or instead.
10
DV172 LCD Monitor Service Guide Circuit Operation Theory 3.2) PWM Control circuit
TL1451 is a dual PWM controller.C765 and R765 decide the working frequency.BLT_ADJ signal is from control board, control pulse width then decide how much energy delivery to CCFL also decide CCFL brightness. Q741 and Q742 be the buffer to rise the drive capability and the totem poles circuit can improve a capable of driving for Q743.C770 decide the striking time delay.
11
DV172 LCD Monitor Service Guide Circuit Operation Theory 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.
C.) 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. (b) 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).

Description Timing adjustment Auto color balance adjustment Color temperature adjustment Writing EDID file
Remark Preset timing SVGA2 60Hz C1, C2 & C3 Analog and Digital
A. Preparation: 1.
Setup input timing to any preset modes, any patterns.
2.
Enter factory mode (press “EXIT” & “ENTER” at the same time, then press “power” button to turn on monitor).
3.
Move blue cursor into “BURN IN MODE” tag and select “YES” to enable burn-in mode.
4.
Power off the monitor, then power on again.
5.
Setup unit and keep it warm up at least 30 minutes.
B. Timing adjustment: (Analog only, it’s no need for DVI-D input source) 1.
Enter factory mode (press “EXIT” & “Enter” at the same time, then press “power” button to turn on monitor).
2.
Select timing from figure-1. The timing marked with star sign (*) have to be adjusted with Analog signals from Chroma video pattern generator..
3.
Press AUTO key to run “AUTO adjustment” function.
4.
Clear user area in EEPROM.
5.
Check the phase of the image; if phase is not perfect adjust it to the best condition.
6.
Adjust the settings to following values: CONTRAST = 55 BRIGHTNESS = 90 OSD TIME = 20 VOLUME = 20 COLOR = USER
7.
Press “EXIT” key until the “SAVE” shows on the OSD to save factory parameters and turn off the monitor power.
