- 17 -TC-20KL05PADJUSTMENTSITEM / PREPARATION PROCEDURE14- VERTICAL DEFLECTION CALIBRATION ANDCONFIRMATION1. Adjust IMAGE to DYNAMIC NORMAL1) V-SLOPE CALIBRATION1. Supply a PHILIPS PAL-M signal.2. Adjust V_SLOPE so that the begin of the blackimage part is aligned with the dividing line of Philipspattern. The dividing line of the Philips pattern circleshould be visible partially.2) V-SHIFT 50Hz CALIBRATION1. Supply a PHILIPS PAL-N signal.2. Adjust the vertical centralization (V-SHIFT 50Hz) so that PHILIPS pattern center be in the center of CRT.3) V-SHIFT 60Hz CALIBRATION1. Supply a MONOSCOPE signal.2. Adjust the vertical centralization (V-SHIFT 60Hz) so that MONOSCOPE pattern center be in the center ofCRT.4) V-AMP 50Hz CALIBRATION1. Supply a PHILIPS PAL-N signal.2. Adjust the vertical height (V-AMP-50Hz) so thatthe pattern PHILIPS circle height has the same dimensionof his width.5) V-AMP 60Hz CALIBRATION1. Supply a MONOSCOPE signal.2. Adjust the vertical height (V-AMP-60Hz) 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.Fig. 1Fig. 215- WHITE BALANCE CALIBRATION1. 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 containburst sign).4. Adjust the IMAGE menu to DINÂMIC NORMAL.5. Fully degauss the CRT by using an external degaussingcoil.6. Position the color analyzer in contact with the CRT face.CALIBRATION:[1] LOW LIGHT CALIBRATION1. Adjust S-BRT, so that Y = 72. Adjust R-CUT OFF, so that x = 0.273 ±0.013. 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 = 1502. Adjust R-DRIVE, so that x = 0,275 ±0.013. 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 thecolor analyzer is below 150, adjust CONTRAST to 50 and press “8” in CHK2 mode.C,DA,B1.5 ~ 2.01.5 ~ 1.6
