5. CUT OFF adjustment
1) Receiver PAL system "MONO SCOPE" signal, warm up the TV set for 15 min.
2) The control terms of adjustment are as follows: color=0; bright=50; contrast
gradient=100.
3) Confirm bus data: RCUT=20; BCUT=20; GCUT=20; GDRV-40; BDRV=40.
4) Press RGB VP button on factory remote controller to let the horizontal line just
appears.
5) Adjust SCREEN VR to make the solid color horizontal line just appears.
6) According this color as benchmark, adjust other two colors bus data (CUT OFF)
to make horizontal line turn to white.
6. White balance adjustment
1) Receive white-up and black-down signal.
2) Set color=0; bright=50; contrast gradient=100.
4) Warm up the TV set over 7 minutes.
5) Paste white balance probe on the center of screen tightly.
6) Adjust bus data RCUT, BCUT, GCUT, BDRV, GDRV to receive benchmark
demand.
7. Adjustment of frame linearity and frame "S" correcting
1) Receive square signal.
2) Set bright=50; contrast gradient =50.
3) Adjust bus data to make frame nonlinear distortion be less than eight percent
(PAL system VLIN; NTSC system VLIS).
4) Adjust bus data VSC to make frame "S" distortion reduce to undermost.
8. Adjustment of frame center and ampl
1) Receive "MONO SCOPE' signal.
2) Set bright=50; contrast gradient=100;
3) Adjust bus data to make frame center deviation be less than one percent (PAL
system VP50; NTSC system HPS).
9. Adjustment of line center
1) Receive "MONO SCOPE" signal.
2) Set bright=50; contrast gradient=100.
3) Adjust bus data to make horizontal position of picture be center (PAL system
HPOS;NTSC system HPS).
