8. Alignments
8.1.3. YPbPr mode display adjustment
8.1.3.1 White Balance adjustment (B)
General set-up :
Equipment Requirement: Minolta CA-110 or Equivalent Color analyzer
Quantum Data Pattern Generator 801GD or 802G or Fluke 54200
Input requirements:
Input Signal Type
: YPbPr signal
1.1080i mode, SMPTE color pattern by 801GD or 802G.or 576i (PAL
system), color bar with black/white pattern by Fluke 54200.
2. Select Smart picture to
Personal
mode and check the x, y data.
Input Signal Strength : 1 Vpp for Y signal ; 350 mVpp for Pb & Pr signal
Input Injection Point : AV1 YPbPr (RAC jack)
1080i, SMPTE color pattern.
576i (PAL system)
,
color bar with black and white pattern
Alignment method:
Initial Set-up:
1. Select source as "
AV1
"
.
2. Set Smart picture as "
Personal
" and to be Contrast =
50
(LPL)
,
Brightness=
50
(LPL)
, at normal menu mode.
3. Apply "SMPTE color" pattern or "color bar with black & white" pattern by signal
generator.
4. Enter factory mode menu: press MENU + Numeric keys "062596" + MENU key
(FAC
mode menu)
. Then select "Factory" item.
Alignment:
1.
At FAC mode menu
, select AUTO_COLOR item. Then press "OK" key 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. Apply full white pattern.
3. Set color temperature to "NORMAL".
4. Copy CLR_TEMP_R, CLR_TEMP_G and CLR_TEMP_B values from "NORMAL" color
temperature in Analog TV mode. Check whether (x,y) color coordinates meet "NORMAL"
color specification below. If color coordinates are out of specification, fine-tune
CLR_TEMP_R, CLR_TEMP_G and CLR_TEMP_B values. Then store those values to
NVM.
5. Set color temperature to "WARM".
6. Copy CLR_TEMP_R, CLR_TEMP_G and CLR_TEMP_B values from "WARM" color
temperature in Analog TV mode. Check whether (x,y) color coordinates meet "WARM"
color specification below. If color coordinates are out of specification, fine-tune
CLR_TEMP_R, CLR_TEMP_G and CLR_TEMP_B values. Then store those values to
NVM.
7. Set color temperature to "COOL".
8. Copy CLR_TEMP_R, CLR_TEMP_G and CLR_TEMP_B values from "COOL" color
temperature in Analog TV mode. Check whether (x,y) color coordinates meet "COOL" color
specification below. If color coordinates are out of specification, fine-tune CLR_TEMP_R,
CLR_TEMP_G and CLR_TEMP_B values. Then store those values to NVM.
