Adjustment Procedures
1. Apply the 10 stair-step (B/W) signal to Composite video input.
2. Connect the Oscilloscope to CN3303-A38 (G out) of G-Board.
3. Adjust Sub contrast so that the B-W (Blanking portion-White) is 0.60V±0.02V.
4. Also connect the oscilloscope to CN3303-A34 (R out) and observe both waveforms simultaneously.
5. Adjust R-drive so that the amplitude of R signal is same as G signal.
6. Connect the Oscilloscope to CN3303-A36 (B out) and CN3303-A38 (G out), and observe the both waveforms simultaneously.
7. Adjust B-drive so that the amplitude of B signal is same as G signal.
