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 M
, C
i
< 20 pF.

White Point Alignments
Steps for white point alignment are listed below
•
Run the PC
•
Connect the USB cable of DB07 board.
•
Run the video pattern generator, adjust %80 white pattern.
•
Run the color Analyzer CA210, make the CAL the probe.
Calibration steps
•
Select the CAL position on the probe.
•
Press button 0-CAL.
•
Wait 5 seconds.
•
Select MEAS position on the probe.
•
Wait a minimum of 15 mins, avg. time is 45 mins.
•
Connect the scart cable to TV.
•
Place the probe across the display (center position, 0.5 cm
at 90 degrees.
•
Check the PC, select the COM port.
•
Select the model type OEM.dat.
•
Press the START button.
•
Wait for the software to set all modes (normal, cool, warm)
•
Wait for the OK-READY sign.
If you don’t have a colour analyser, you can use the default
values. This is the next best solution.
