* 1: Test pattern signal is displayed after adjusted with white balance and gamma correction.
* 2: Test pattern signal is displayed after adjusted with gamma correction.
* 3: Test pattern signal is displayed to LCD panel without adjustment. (Mainly used to
measure optical characteristics.)
- Normal display of LCD pattern indicates at least that the status of optical engine including the
LCD board is normal.
B) Scaler Patterns: These patterns are made from scaler IC on digital board which are ranged from
Cross Bar(01) to Box(05) and from Step 64(15) to Flicker_25(23) pattern.
- OSD Mixed: Only available on Scaler Patterns.
* 0: Test pattern will disappear when the display is returned to the menu at test pattern display status.

1) LCD EEP &DIG EEP
- LCD board and digital board can simultaneously backup the data of gamma (uniformity) and
flicker adjustment, because they have the same capacity of EEPROM.
- LCD EEP: It indicates the status of EEPROM in the LCD board.
* Cremo: With the eguipment used during engine assembly at the factory, it indicates that the adjusted
gamma and flicker data is stored.
* Download: It indicates that the gamma and flicker data on the digital board is downloaded and
stored through D->L Trans(14) operation.
At replacement of the LCD board, 14 D->L Trans operation should be carried out.
* Default: It indicates that the default value of Gamma and flicker data is stored.
- DIG EEP: It indicates the status of the EEPROM of the digital board.
* Download: It indicates that the gamma and flicker data on the LCD board is downloaded and
stored through factory reset operation. At replacement of the digital board, the data in EEPROM of
the LCD board should be backed up to EEPROM of the new digital board by factory reset.
* Default: It indicates that the default value of gamma and flicker data is stored.
