5. Press hot-key “CONTRAST” to run “White Balance” function. (This procedure will get optimal gain/offset (clamp) values)
Checking if the picture is O.K., or reject this monitor and check its circuit board or wire/cable connection.
6.
D. Color temperature measurement
1. Setup input timing ICL-605 (1280x1024/75Hz), pattern 41 (full white color pattern) with Analog signals from Chroma video pattern generator.
2. Make sure ADC calibration (White Balance) had already been done.
3. Measure color temperature C1/Bluish, C2/Reddish & C3/Normal to meet following spec. requirement by Minolta CA­110 (or equivalent equipment).
Color temperature X+- 0.283+(-) 0.03 (C1/9300K/Bluish set on OSD) Y+- 0.297+(-) 0.03 Color temperature X+- 0.326+(-) 0.03 (C2/5800K/Reddish set on OSD) Y+- 0.342+(-) 0.03 Color temperature X+- 0.313+(-) 0.03 (C3/6500K/sRGB set on OSD) Y+- 0.329+(-) 0.03
4. Turns off the monitor power.
E. Writing EDID data into monitor
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 analog EDID data into EEPROM for analog input (ie. 15-pin D-sub).
5. Repeat step 4 and write the digital EDID data into EEPROM for DVI-D input (ie. 24-pin DVI-D).
6. Read both EEPROM data and confirm it to match with the C212 definition.
(Note: The DVI-D input may not operation correctly if the digital EDID data do not exist.)

Circuit Operation Theory
I. Introduction:
The Q9T4 is a 19” SXGA (1280x1024), 262K (R/G/B 6-bit for V.2 version)/16.2M colors (R/G/B 6-bit + FRC
for V.5 version) TFT LCD monitor with multi-media function. It’s a Dual (analog and digital) interface LCD monitor with a 15 pins D-sub signal cable and a 24 pins DVI-D cable. 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 “iKey” which can auto adjusting all controlled items. Q9T4 also offer DDC2 function to meet VESA standard.
II. Block diagram
The Q9T4 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 an interface board. The block diagram is shown as below.

(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 TSU56AL receives video data and optimizes the image automatically. It also supports input source selection, maximum 8 multi-color fonts as well as 256 color palette to form a bitmap OSD, and keypad controlling. The output data are sent to LCD module.
(b) IC introduction:
1) DDC (Display Data Channel) function: We use DDC IC to support DDC2B 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) TSU56AL IC: There are A/D, Scaling and OSD functions in the TSU56AL 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.
Circuit Operation Theory
3) EEPROM: We use 24C04 to store all the adjustable data and user settings, and use 24C02 to store DVI EDID data.
4) MTV312M64: 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.

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 voltage-snubber circuit. R615 is current sense resistor to control output power. (See Fig.4)

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 setting-point. When the current setting-point falls below a given value. The output power demand diminish, the IC automatically enters the so-called skip cycle mode and provides excellent efficiency.

3.3 Oscillator Circuit
Royer circuit uses the characteristic of transformer saturation to oscillate. When the DC power inject, Q808 or Q809 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 T801 will get a Sin Wave to turn on CCFL.
A-4.) 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,
select (unselect) adjustment or adjusting bar.
(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).
