3-4-3 Conditions for Measurement1. On the basis of toshiba ABL pattern : High Light level (57 IRE)

- INPUT SIGNAL GENERATOR : MSPG-925LTH* Mode NO 2 : 744X484@60 Hz

NO 6 : 1280X720@60 HzNO 21 : 1024X768@60 Hz

* Pattern NO 36 : 16 Color Pattern NO 16 : Toshiba ABL Pattern

2. Optical measuring device : CA210 (FL)Please use the MSPG-925 LTH generator for model LE26M51B/LE32M51B/LE40M51B/LE46M51B.

3-4-4 Method of Adjustment1. Adjust the white balance of AV, Component and DVI Modes.

(AV Component)a) Set the input to the mode in which the adjustment will be made

(RF DTV PC DVI).* Input signal - VIDEO Mode : Model #2 (744*484 Mode), Pattern #16

- DTV,DVI Mode : Model #6 (1280*720 Mode), Pattern #16 - HDMI Mode: Model #6(1280*720 Mode), Pattern #16

b) Enter factory color control, confirm the data.

c) Adjust the low light. (Refer to table 1, 2 in adjustment position by mode)- Adjust sub - Brightness to set the 'Y' value.- Adjust red offset ('x') and blue offset ('y') to the color coordinates.

* Do not adjust green offset data.

d) Adjust the high light. (Refer to table 1, 2 in adjustment position by mode)- Adjust red gain ('x') and blue gain ('y') to the color coordinates.* Do not adjust the green gain and sub-contrast (Y) data.
