Alignments
8.
Make the following settings in the normal
user menu
, when the
television is in TV Mode:
Table 8-1 User menu settings for White Tone alignment
Go to WHITE TONE in SAM and set NORMAL GREEN to:
Table 8-2 Service menu settings for White Tone alignment
1.
Measure with a calibrated (phosphor- independent) color
analyzer (e.g. Minolta CA-200) in the center of the screen
(use a contact less analyzer, e.g. Minolta CA-210, to align
the LCD TV). The analyzer may not touch the screen, and
the measurement must be done in a dark environment.
Note: The color analyzer must be calibrated for the LCD or
Plasma panel in question. See the manual of the color
analyzer for the procedure on how to perform this
calibration.
2.
Leave the value with the lowest output on the initial value.
3.
Align the NORMAL white points, by lowering the other two
colors, to the right x-y coordinates (see table "White Tone
alignment values").
Note:
To prevent clipping of the color, these values must
only be lowered!
Table 8-3 White Tone alignment values
Only the values for NORMAL are aligned with X, Y values. The
delta values for COOL and WARM are given below.
Table 8-4 Fixed delta values
After the alignment is finished, switch the set to STANDBY, in
order to store the alignments.
Note: When disconnecting the power before doing this, the
settings will not be stored.
Method 2 (without color analyzer):
If you do not have a color analyzer, you can use the default
values. These values are based on the average values in
production.
•
Set the values for the NORMAL color temperature. Given
in the table “Average statistical values for NORMAL” from
production.
•
Set the delta values for the COOL and WARM mode. See
table: “Fixed delta values.”
After the alignment is finished, switch the set to STANDBY, in
order to store the alignments.
Note: When disconnecting the power before doing this, the
settings will not be stored.

Tuner Adjustment
AGC (RF AGC Take Over Point)
Set pattern generator (e.g. PM5580) with color bar pattern and
connect to aerial input with RF signal amplitude -10mV and set
frequency for NTSC to 61.25 MHz (channel 3).
•
Activate the SAM-menu. Go to the sub-menu TUNER,
select the sub-menu option AFC WINDOW and adjust the
value to “100 kHz”.
•
Select the AGC sub-menu.
•
Connect a DC multi-meter to test point F306 or pin1 of the
tuner.
•
Adjust the AGC until the voltage at pin 1 of the tuner is
3.3 V +0.5 / -1.0.
•
The value can be increased or decreased by pressing the
RIGHT/LEFT cursor button on the RC.
•
Switch the set to STAND-BY to store the data.
