General set-up
Equipment Requirements:
Knoica Minolta CS-200 or equivalent instrument. Quantum Data Pattern Generator 881 or equivalent instrument. Input requirements:
Input signal type: YPbPr signal
1. 1080i/25mode, TVBar100 pattern by QuantumData 881.
2. Select Picture mode to “Personal” mode and adjust the x, y data.
Input Signal Strength: 1 Vpp for Y signal ; 700 mVpp for Pb & Pr signal
Input Injection Point: YPbPr (RAC jack)
1080i/25, TVBar100 pattern
Alignment method:
Initial Set-up:
1. Select source as “YPbPr”.
2. Set Smart Picture mode as “Personal” and then adjust Contrast = 58, Brightness=48, Color=58, set Color Temp. to be “cool” mode.
3. Apply “TVBar100” pattern which is color bar pattern by signal generator.
4. Enter “factory mode menu”: press MENU + Numeric keys “1999”
Alignment:
1. At factory mode menu, select AUTO_COLOR item. Then press “OK” key of remote control to adjust ADC_GAIN_R, ADC_GAIN_G,
ADC_GAIN_B and ADC_OFFSET_R, ADC_OFFSET_G, ADC_OFFSET_B. Then store those values to NVM.
2. Check the 16 grayscale pattern should be distinguished and color bar is correct
3. Reset AV setting, picture mode shall be recalled to be “Vivid” and Contrast=58, Brightness=48; Color=58.

3. Reset AV setting, picture mode shall be recalled to be “Vivid” and Contrast=58, Brightness=48; Color=58.
Sharp EU 2k10 models have no need to operate “AUTO_COLOR” function, due to EFUSE is set “Disable” within NVM for defult. These ADC values will
be produced by Main chip (MT5363) interal defination.
White balance adjustment
Alignment method:
Initial Set-up:
1. Select source as “YPbPr”.
2. Set Contrast = 58 and Brightness=48, Color=58, at normal menu mode.
3. Apply “80% white pattern or Flat 80 pattern by Component video generator.
4. Enter factory mode menu: press MENU + Numeric keys 1999”.

Color temperature Normal/Warm/Cool (x, y) co-ordinates specification:
Note:
1. Use Knoica Minolta CS-200 for color coordinates and luminance check.
2. For suitable mass production at factory, colour analyzers CA-210 can be applied. But, befor measureing ,all CA-210 should be coordinates and proofread with a Charoma Meter (CS-200) or equivalent instrument and a reference TV set.
3. Check the luminance at the center of the screen with 100% White. And to set Brightness control at 100; Contrast control at 100. Luminance
