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, backlight=100, 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”+ press PRE PR.
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.
Note:
Sharp EU 2k11 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.

4. Enter factory mode menu: press MENU + Numeric keys “1999” + press PRE PR.
Alignment:
1. Apply Flat80 pattern (80% white pattern).
2. Set color temperature to “NORMAL”.
3. At factory mode menu, adjust the Scaler R Gain, Scaler G Gain, Scaler B Gain values to meet “NORMAL” color coordinates specification below. Then store those values to NVM
4. Set color temperature to “COOL”.
5. At factory mode menu, adjust the Scaler R Gain, Scaler G Gain, Scaler B Gain values to meet “COOL” color coordinates specification below.
Then store those values to NVM
6. Set color temperature to “WARM”.
7. At factory mode menu, adjust the Scaler R Gain, Scaler G Gain, Scaler B Gain values to meet “WARM” color coordinates specification below. Then store those values to NVM

Color temperature Normal/Warm/Cool (x, y) co-ordinates specification
Normal (9000K) x = 0.289±0.003 y = 0.291±0.003
Cool (12000K) x = 0.272±0.003 y = 0.277±0.003
Warm (6500K) x = 0.314±0.003 y = 0.319±0.003
Cool (12000K) x = 0.272±0.003 y = 0.277±0.003
Warm (6500K) x = 0.314±0.003 y = 0.319±0.003
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; backlight control at 100.
Luminance > 200 cd/m2 (Typ.) [ For LC-19LE430E only at color temp.- *warm mode ]
> 200 cd/m2 (Typ.) [ For LC-22LE430E only at color temp.- *warm mode ]
> 400 cd/m2 (Typ.) [ For LC-26LE430E only at color temp.- cool mode ]
> 450 cd/m2 (Typ.) [ For LC-32LE430E only at color temp.- cool mode ]
> 450 cd/m2 (Typ.) [ For LC-37LE320E/RU/E(UK) only at color temp.- cool mode ]
> 450 cd/m2 (Typ.) [ For LC-42LE320E/RU/E(UK) only at color temp.- cool mode ]
4. The defult values of Scaler R Gain, Scaler G Gain, Scaler B Gain are all 128. When panel WD is made adjustment, the three values could not be over 128. That is preventing color saturation after adjusting Contrast and Brightness setting at main menu.

PC mode display adjustment
1. Display quality adjustment
Use timing mode as describe above, and use the POPO (pixel on pixel off) pattern to adjust the clock until no stripe and adjust the phase until clear picture.(“Auto” will be done every time switching to PC mode and mode change) Check all preset 7 modes.
