Apply “80% white pattern or Flat80 pattern by Component video generator.4. Enter factory mode menu: press MENU + Numeric keys 1999”.Alignment:1. Apply Flat 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 NVM4. 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 NVM6. 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 NVMColor temperature Normal/Warm/Cool (x, y) co-ordinates specification:`Table 5: Reading with Knoica Minolta CS-200.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, beformeasureing ,all CA-210 should be coordinates and proofread with a Charoma Meter (CS-200) orequivalent 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 > 200cd/m2 (Typ.) [ For LE19K097/LT19Z6 only at color temp.- *warm mode ]> 200 cd/m2 (Typ.) [ For LE22K097/LT22Z6 only at color temp.- *warm mode ]> 250 cd/m2 (Typ.) [ For LE24K097/LT24Z6 only at color temp.- *warm mode ]4. The defult values of Scaler R Gain, Scaler G Gain, Scaler B Gain are all 128. When panel WD is madeadjustment, the three values could not be over 128. That is preventing color saturation after adjustingContrast and Brithness setting at main menu.Picture Mode x yNormal (9000oK) 0.289±0.003 0.291±0.003Cool (12000oK) 0.272±0.003 0.277±0.003Warm (6500oK) 0.314±0.003 0.319±0.003
