VIDEO SYSTEM ADJUSTMENTS
Before perform the video system adjustments, check that the data
of page: 0, address: 10 is “00”.
If not, select page: 0, address: 10, and set the data “00”.
Adjusting Procedure:
1) Origin oscillation check
2) S VIDEO OUT Y level adjustment
3) S VIDEO OUT chroma level adjustment
4) VIDEO OUT level check
5) VIDEO OUT level check (E-E)
6) COMPONENT OUT Y level adjustment (D1 SMPTE)
7) COMPONENT OUT Pb level adjustment (D1 SMPTE)
8) COMPONENT OUT Pr level adjustment (D1 SMPTE)
9) COMPONENT OUT Y level adjustment (D1 BETACAM)
10) COMPONENT OUT Pb level adjustment (D1 BETACAM)
11) COMPONENT OUT Pr level adjustment (D1 BETACAM)

Origin Oscillation Check (VD-036 board)
Check the frequency of the clock for synchronization.
If deviated, the synchronization will be disrupted and the color
will become inconsistent.
