Electrical Alignments
8.1.1
White Balance Adjustment (PC Mode)
Equipment Requirements: Colour analyser.
Figure 8-1 Colour analyser
Access the “Factory” mode (RS232) in auto-alignment
system.The communication protocol switches to RS232.
Input Signal Type: PC signal
In “Factory” mode, apply 1360x768/60Hz with TVBAR100
pattern and set “brightness” and “contrast” to 50%.
Activate AUTO-COLOR function for auto ADC offset and gain
setup.
Figure 8-2 TVBAR100
Colour Temp Alignment:
Apply a 1360x768/60Hz signal with white pattern, set
“brightness” at 100%, and “contrast” at 50%. Adjust the R, G,
and B Sub-Gain for the screen centre.
The 1931 CIE chromaticity (x, y) co-ordinates shall be:
Table 8-1 Reading With Minolta CA-210
If you do not have a CA-210, the following R, G, and B values
are for your reference.
Table 8-2 Reference Value of R, G, and B
Luminance > 400 cd/m2 in the centre of the screen when both
“contrast” and “brightness” are set to 100%. This group setting
about colour temperature is also applied in HDMI1/HDMI2/
CVI1/CVI2/AV/SideAV/PC. It means that all use the same
setting.
Display quality adjustment:
Use timing mode as described in 2.2, and uses the POPO
(Pixel On Pixel Off) pattern to adjust the clock until no stripe
and adjust the phase until clear picture. (AUTO ADJUST hot
key: press VOLUME n and keys together for 1
second). Check all six preset modes.
Check the analogue interface cable.
Check the colour poor and noise condition of 64 gray scale
pattern.
8.1.2
White-D Adjustment (Comp. Mode)
Apply 1080i/50Hz and the pattern TVBAR100 (see figure 8-2).
Alignment method:
Set Smart picture as “Personal” (Brightness= 50, Color= 50,
Contrast= 50);
Access the factory OSD first, then enable AUTO-COLOR to get
Comp ADC OFFSET and Comp ADC GAIN. Check if 64 gray
scales can be distinguished.
Colour Temp Alignments: Check chromaticity (x, y) co-
ordinates specification as in table above.
Luminance> 400 cd/m2 in the centre of the screen in RICH
mode.
