Q7C3 LCD Monitor Service Guide Alignment Procedure
1. Alignment procedure (for function adjustment)
A. Preparation: 1. 2. 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 message. 4. Press "RIGHT" to Calibrate ADC. 5. Setup input timing ICL-605, 32 -Gray pattern. 6. Checking if the picture is no good, reject this monitor. D. Color adjustment: 1. Setup input timing ICL-605, white pattern. 2. Measure color temperature by Minolta CA-110 (or equivalent equipment). 3. Alignment the color temperature Bluish, Reddish & sRGB. The color temperature specification as follows: White Balance (Bluish, 9300K set on OSD) White Balance (Reddish, 5800K set on OSD) White Balance (sRGB, 6500K set on OSD) X+Y+X+Y+X+Y+0.283+(-) 0.03 0.297+(-) 0.03 0. 326+(-) 0.03 0. 342+(-) 0.03 0. 313+(-) 0.03 0. 329 +(-) 0.03

4. 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 document definition.
