I) Adjustment of B+ voltage
1. Apply 110-240VAC(±5V) to mains power input, and Philips standard testing pattern to RF input.
2. Adjust VR801 in STANDARD mode until voltage at TP2 (B +) is 112V ±0.5V.
II) Adjustment of VCO and AFT
1. Apply a 38.9MHz signal to the IF input.
2. Monitor the DC voltage at pin 48 of IC201.
3. Adjust T201 until the voltage at pin 48 of IC201 becomes 4.62 +/- 0.2V (the picture must stable).
4. Enter D-mode and press the AFT (update/BBE) button. It will start Auto AFT Adjustment and the
screen will show “PIFAFT OK” if the process is finished.
III) NICAM Adjustment (for NICAM model only)
1. Apply a 38.9MHz color bar with NICAM signal to the IF input.
2. Monitor the DC voltage at pin 15 of IC1101.
3. Adjust T1101 until the voltage at pin 15 of IC1101 becomes 2.5 +/- 0.1V.
4. Then check the waveform at pin 4 and 6 of P1103 and it must show correct audio signal.

1. Enter D-mode, and connect the probe of Oscilloscope to the conjunction between R217 and P201
(B-out).
2. Apply the Grey-scale/Colour-bar (NTSC signal) to the AV input, in STANDARD status.
3. Select CNTC to adjust the sub-contrast, until that the amplitude “A” is 2.5V
4. Select COLC to adjust the sub-colour by tuning the amplitude of “a” and “d” to the same.
5. Select TNTC to adjust the sub-tint by tuning the amplitude of “b” and “c” to the same.
6. Apply the Grey-scale/Colour-bar (PAL signal) to the AV input, in STANDARD status.
7. Select COLP to adjust the sub-colour by tuning the amplitude of “a”, “b”, “c” and “d” to the
same.

VI) Adjustment of Focus, Screen Voltage and Sub-brightness
1. Receive a crosshatch pattern.
2. Adjust the “FOCUS” VR on the flyback the make the picture clear.
3. Enter D-mode and press “1--” key and the screen will become a horizontal line. Then adjust the
“SCREEN” VR on the flyback transformer to set the intensity of the line to a minimum visible
level (the line can just be seen).
4. Pr ess “1--” key again and the TV will become full raster.
5. Select BRTC to adjust the sub-brightness, until that the 2
be seen.
VII) Adjustment of White balance
1. Receive a black and white pattern at STANDARD status.
2. Use a color analyzer to measure the black side of the screen. By changing the value of BCUT and
GCUT, set the reading of the color analyzer to x=284, y=299.
3. T hen measure the white side of the screen. By changing the value of BDRV and GDRV, set the
reading of the color analyzer to x=284, y=299.
4. Repeat step 2&3 until you can get the correct reading for both black and white sides.
VIII) Adjustment of Pincushion and Picture Width (for pure flat model only)
1. Receive a crosshatch pattern.
2. Adjust VR302 until the vertical line become straight.
3. Adjust VR303 for horizontal size.

IX) Adjustment of Picture Geometry (PAL)
1. Apply the crosshatch pattern (PAL signal) to the RF input, in STANDARD status.
2. Select HPOS50 to adjust the Horizontal center.
3. Select VPOS50 to adjust the Vertical center.
4. Select HIGH50 to adjust the Vertical amplitude.
5. Select VLIN50 to adjust the vertical linearity.
6. Select VSC50 to adjust the vertical S-correction.
X) Adjustment of Picture Geometry (NTSC)
1. Apply the crosshatch pattern (NTSC signal) to the RF input, in STANDARD status.
2. Select HPOS60 to adjust the Horizontal center.
3. Select VPOS60 to adjust the Vertical center.
4. Select HIGH60 to adjust the Vertical amplitude.
5. Select VLIN60 to adjust the vertical linearity.
6. Select VSC60 to adjust the vertical S-correction.
XI) Adjustment of OSD position
1. Enter D-mode and press key “0”, then choose OSD item and adjust the OSD horizontal position.
2. Enter D-mode and press key “2”, then choose the OSDV50 item and adjust the OSD horizontal
position.
3. Enter D-mode and press key “3”, then choose the OSDV60 item and adjust the OSD horizontal
position.
