8. Alignments
4.4 Method of Alignment :
4.4.1 Set audio volume Loudspeakers to max : (+12dB avip setting)
4.4.2 Via IIC, adjust the 'PLL offset' register (address 9E, sub-address 02,
bit D5 to D0) value to get the lowest noise at audio output (I905).
4.4.3 NVM FactAlignMainIfPLLOffsetNeg at sub-address
006Chex, 1037hex, 1630hex.
5. TV Mode display adjustment
5.1 White balance adjustment (B)
5.1.1 General set-up :
Equipment Requirements: Color analyzer.
Input requirements:
Input Signal Type : RF signal
1. Set to NTSC system, frequency=187.25MHZ ( for NAFTA
model ), with white pattern of 100%
2. Select Smart picture to Personal mode and check the x, y data.
Input Signal Strength : 10mV (80 dBuV) terminal voltage.
Input Injection Point : TV Tuner input
Alignment method:
Initial Set-up
:
1. Set TV Brightness=60; Contrast =95 in Factory mode.
2. Set Smart picture as "Personal"
3. Apply "100% Full White" pattern by TV pattern generator.
Alignment : Adjust the RGB White point in Factory Mode
for "NORMAL","WARM" and "COOL" color temperatures.
1. Check (X, Y) co-ordinates as below:
Table 3: Reading with Minolta CA-110.
2. Check the gray pattern should be distinguished and color bar
is correct
Note: 1. Use Minolta CA-110 for color coordinates and
luminance check.
2. Luminance> 400 cd/m

in the center of the screen
at RGB White point set to 127 and Brightness
control; Contrast control at 100
3. Set smart picture to personal, brightness to 55 &
contrast to 95 after alignment.
