Description
Q7T3-FP737S Dual function LCD Monitor Service Guide Alignment Procedure 1. Alignment procedure (for function adjustment) A. Preparation: 1.
Setup input timing ICL-605, 32-Grays pattern.
2.
Setup unit and keep it warm up at least 30 minutes.
B. Timing adjustment: 1. Enter factory setting area (press “ENTER”, “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 “ENTER”, “EXIT” and then press “SOFTPOWER”). 2. Setup input timing ICL-605 (1280*1024 75Hz), 5-MOSAIC pattern.(timing 202 pattern 42) 3. Press”I-key”,to enter window for whitebalance and burning mode. 4. Press “Whitebalance”, 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)

Q7T3-FP737S Dual function LCD Monitor Service Guide Alignment Procedure 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. 6. Connect PC to monitor with a DVI-D signal cable. 7. Please refer to the C212 for the correct EDID file. 8. Runs the writing program to write the EDID file into EEPROM for DVI input, ie. 24-pin DVI-D. 9. Read both EEPROM data and confirm it to match with the C212 document definition.

Q7T3(CPT panel) LCD Monitor Service Guide Engineering Specification Notes： (1) If the incoming display mode is not supported by this I/F board listed above, the picture can show up or doesn’t which is unpredictable, even the picture can display but probably isn’t good or clear. (2) Some signals from graphics board may not function properly. (3) “P”, “N” stands for “Positive”, “Negative” polarity of incoming HSYNC/VSYNC(input timing). (4) OSD will show “No Signal” message on the screen as below to indicate it while no display mode inputs. (5) OSD will show “Out of Range” message on the screen to indicate it while input display mode meet the following condition (a) The resolution is large than 1280x1024. (b) The resolution is 1280x1024 but it frequency of vertical sync (Fv) is large than 77Hz. (c) The frequency of horizontal sync (Fh) is large than 82KHz. (d) The frequency of vertical sync (Fv) is large than 76Hz.

Note： 1. Viewing Angle, Contrast Ratio, Response Time, Reflectance, and Chromaticity are measured at panel center. 2. Viewing Angle（θ, ψ） Measurement is done on position 1. Viewing angle origine is the axis normal to the flat panel. Left (L) and Right (R) value are the maximum angles for which CR=10. Up (U) and (D) value are the maximum angles for which CR=10.
