480i INPUT
ADJUSTMENT CONDITIONS: 480i 75% colour bar signal input Used
device name: LEADER LT448 Signal name: COLOUR BAR
Use the LT-448-compatible third one
of three color bars. Setting value: 15: 480i/60 H: 15.73 kHz, V: 29.97 Hz.
- ADJUSTMENT PROCEDURE: Set AUTO GAIN-OFFSET on page 4 (M2-SD) of the adjustment process DVP hierarchy to ON.
=================================================================================
ADJSUTMENT CONDITION: Receive the PAL standard color bar signal.
- If the maximum value of “PAL TAMP1” on page 1 of adjustment process DVP hierarchy is not in the range of values in the list below, adjust “PAL TAMP1” on the same page so that the maximum value of “Y” is in the range of values in the list below.
Note that the setting value may vary by model.
- When pressing the TAMP1 direct keys, adjustment of “PAL TAMP1” is complete. Then, The values of “NTSC TAMP1” and “SECAM TAMP1” are automatically set.
(NTSC: Value of PAL –7, SECAM: The
same value as PAL).

WHITE BALANCE ADJUSTMENT: Adjust the white 144 gradation using
RGB CUTOFF2 and then the white 73 gradation with RGB-GAIN.
TEST SIGNAL ADJUSTMENT
- [Input signal] : Display the WB test signals with built-in DVP of white 56% (144 gradations) and 29% (73 gradations) on the left and right of the screen respectively by using the remote control code “011110010001010”.
[Adjustment value]:
- White 56% x = 0.261 ±0.004 ±0.01 Radius from the center point x = 0.277 ±0.004 ±0.01 Radius from the center point.
- White 29% x = 0.261 ±0.002 ±0.01 Radius from the center point x = 0.277 ±0.002 ±0.01 Radius from the center point.
[Adjustment method by bus]:
- Cutoff: RGB CUTOFF2 G CUTOFF2 = Fixed to 0. Vary RB CUTOFF2: Adjustment range: ±30.
- Gain: RGB-GAIN G-GAIN = Fixed to 0. Vary RB-GAIN. Adjustment range: ±30.
(The adjustment value is measured
with MINOLTA CA-210 and the correction mode is measured in the mode compatible
with CH02 “TOPCON”.)
- Perform the factory setting using the remote control for adjustment. (This setting must be done after performing the MCL data setting.)
- “H” standing for factory setting 1, “M” standing for factory setting 2 or “X” standing for factory setting 3 is displayed in the upper left portion of the screen by continuing to press the Factory Setting key on the remote control for adjustment.
- When “SETTING COMPLETE” is displayed in the middle of the screen after a few seconds, setting is complete.
- Turn off the power
NOTE: Set the Power switch to “OFF”
