4-8. SUB DECODER SUB CONTRAST
ADJUSTMENT (FOR Y/C INPUT)
1. Receive the 100 % color bar (480i, 7.5% setup, Y/C) signal
with VIDEO 3 input. (White to Black Level Y : 714 ±10 mVp-p,
Burst Level C : 285 ±10 mVp-p)
2. Connect the oscilloscope between CN005 <
on the B board and ground.
3. Set in the service mode and select the category "2103-2".
4. Adjust "2 SCON" so that the waveform level is 1.400 ±0.035
Vp-p.
5. After adjustment finished, press "[MUTING]" + "[ENTER]"
buttons on the commander to write the data to the NVM.
