Alignment and Adjustments
2-2 WHITE Balance Coordinates
2-2-1 PS42D4S White Balance Adjustment
1. W/B Adjustment is required for the following six modes :
DVI ' Component(1080i) ' Component(720p) ' PC ' VIDEO (Video port) ' VIDEO (Graphic port)
2. Adjustment Method (Signal equipment : MSPG-925LTH, Measurement equipment : CA210)
■ MSPG-925LTH
Equipment that outputs analog and digital signals simultaneously
(Analog / Digital signal output / TV signal output (S-Video included) / HDTV signal output)
-. Digital Serial : TMDS (DVI24, SiI160) + DVI-I (Analog, Digital)
-. Monitor Signal (Analog): R, G, B, HS, VS, CS
-. TV Signal (CVBS) : NTSC M, NTSC J (7.5 IRE On/Off) (BNC or RCA), PAL B, D, G, H, I, PAL M, Nc
-. D-TV Signal (1080i, 720p, 480p)
MSPG-925 is used to adjust the W/B

■ CA210 : Color Analyzers adjusting brightness, chromaticity and etc.
-. R.G.B monochrome correction, brightness and gamma character adjustment
-. White Balance and flickering measurement
(1) Adjust the TV by varying the panel values and the video DNIe register in order th determine the reference W/B
with a DVI input.
(2) For Component mode, adjust the register of AD9883 to align the DTV signal to the DNIe and logic panel value .
(At this time, do not adjust the gain of AD9883 ' the Highlight W/B does not need to be adjusted since its deviation falls within
valid distribution range.)
(3) PC adjustment is same as Component adjustment.
(The offset can be applied to the values obtained through DTV adjustment. However, additional adjustment is required for Y,
Cb, and Cr, since PC processes R, G, and B signals.)
* Attention for Component/PC adjustment
- Load the Auto color pattern. (Pattern #21)
- Excute factory mode auto color to adjust gain and offset.
- Load the Toshiba Pattern.(Pattern #16) and then adjust W/B.
2-2
Auto color pattern appears as black and white.
♣
♣
problems may occur if pattern #21 or similar
is not used.
♣ When factory mode auto color is executed, gain and
offset value is adjusted automatically.
