VERTICAL DEFLECTION CALIBRATION AND
CONFIRMATION
1. Adjust IMAGE to DYNAMIC NORMAL
1) V-SLOPE CALIBRATION
1.
Supply a PHILIPS PAL-M signal.
2. Adjust V_SLOPE <CHK3> so that the begin of the black
image part is aligned with the dividing line of Philips
pattern. The dividing line of the Philips pattern circle
should be visible partially.
2) V-SHIFT 50Hz CALIBRATION
1.
Supply a PHILIPS PAL-N signal.
2. Adjust the vertical centralization (V-SHIFT 50Hz) <CHK3>
so that PHILIPS pattern center be in the center of CRT.
3) V-SHIFT 60Hz CALIBRATION
1.
Supply a MONOSCOPE signal.
2. Adjust the vertical centralization (V-SHIFT 60Hz) <CHK3>
so that MONOSCOPE pattern center be in the center of
CRT.
4) V-AMP 50Hz CALIBRATION
1.
Supply a PHILIPS PAL-N signal.
2. Adjust the vertical height (V-AMP-50Hz) <CHK3> so that
the pattern PHILIPS circle height has the same dimension
of his width.
5) V-AMP 60Hz CALIBRATION
1.
Supply a MONOSCOPE signal.
2. Adjust the vertical height (V-AMP-60Hz) <CHK3> so that
"C" and "D" values in illustration 2 it is 1.5 ~ 2.0 and to "A"
and "B" values in illustration 2 it is 1.5 ~ 1.6.
3. To MEMORIZE in EEPROM.

15- WHITE BALANCE CALIBRATION
1. Adjust the HELMHOLTZ device to local magnetic field.
2. Let the set warm up for a minimum of 30 minutes.
3. Receive a white balance. (This sign should contain
burst sign).
4. Adjust the IMAGE menu to DINÂMIC NORMAL.
5. Fully degauss the CRT by using an external degaussing
coil.
6. Position the color analyzer in contact with the CRT face.
CALIBRATION:
[1] LOW LIGHT CALIBRATION
1. Adjust S-BRT, so that Y = 7
2. Adjust R-CUT OFF, so that x = 0.273 ±0.01
3. Adjust G-CUT OFF, so that
y = 0,283 ±0.01
[2] HIGH LIGHT CALIBRATION
(Confirm that G-DRIVE is 31 DAC)
1. Adjust S-BRT, so that Y = 150
2. Adjust R-DRIVE, so that x =
0,275 ±0.01
3. Adjust B-DRIVE, so that y =
0,284 ±0.01
[3] Repeat the procedures [1] and [2].
Assure that not entering light for the meter borders and that the CUT OFF voltage calibration has been done. If the value in the
color analyzer is below 150, adjust CONTRAST to 50 and press “8” in CHK2 mode.
