6.1 General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
• Power supply voltage: 90 - 264 V
AC
, 50/ 60 ± 3 Hz.
• Connect the set to the mains via an isolation transformer
with low internal resistance.
• Allow the set to warm up for approximately 15 minutes.
• Measure voltages and waveforms in relation to correct
ground (e.g. measure audio signals in relation to
AUDIO_GND).
Caution: It is not allowed to use heat sinks as ground.
• Test probe: R
i
> 10 MW, C
i
< 20 pF.
• Use an isolated trimmer/screwdriver to perform
alignments.
6.2 Hardware Alignments
Not applicable.
6.3 Software Alignments
Put the set in SAM mode (see Chapter 5. Service Modes, Error
Codes, and Fault Finding). The SAM menu will now appear on
the screen. Select RGB Align and go to one of the sub menus.
The alignments are explained below.
The following items can be aligned:
• White point.
To store the data:
• Press OK on the RC before the cursor is moved to the
left.
• Select “Store” and press OK on the RC.
• Switch the set to stand-by mode.
For the next alignments, supply the following test signals via a
video generator to the RF input:
• EU/AP-PAL models: a PAL B/G TV-signal with a signal
strength of at least 1 mV and a frequency of 475.25 MHz
• US/AP-NTSC models: an NTSC M/N TV-signal with a
signal strength of at least 1 mV and a frequency of
61.25 MHz (channel 3).
• LATAM models: an NTSC M TV-signal with a signal
strength of at least 1 mV and a frequency of
61.25 MHz (channel 3).
6.3.1 RGB Alignment
Before alignment, set the picture as follows:
White Tone Alignment:
• Activate SAM.
• Select “RGB Align.” and choose a color temperature.
• Use a 100% white screen as input signal and set the
following values:
– “Red BL Offset” and “Green BL Offset” to “7” (if
present).
– All “White point” values initial to “128”.
In case you have a colour analyser:
• Measure with a calibrated (phosphor- independent) color
analyser (e.g. Minolta CA-210) in the centre of the screen.
Consequently, the measurement needs to be done in a
dark environment.
• Adjust the correct x, y coordinates (while holding one of the
White point registers R, G or B on max. value) by means of
decreasing the value of one or two other white points to the
correct x, y coordinates (see Table 6-1 White D alignment
values). Tolerance: dx: ± 0.003, dy: ± 0.003.
• Repeat this step for the other colour Temperatures that
need to be aligned.
• When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.
Table 6-1 White D alignment values
If you do not have a colour analyser, you can use the default
values. This is the next best solution. The default values are
average values coming from production (statistics).
6.3.2 Display Adjustment
You can use the default values. The default values are average
values coming from production.
• Enter SAM mode.
• Select a colour temperature (e.g. COOL, NORMAL, or
WARM).
• Set the RED, GREEN and BLUE default values according
to the values in Table 6-2
.
• When finished press OK on the RC, then press STORE to
store the aligned values to the NVM.
• Restore the initial picture settings after the alignments.
