1. Adjustment jig
The color pattern generator that can output 100% in NTSC/PAL/
HD color bar signal to the component and the composite at the same
time is necessary for the adjustment.
When there is no color pattern generator, it is possible to substitute
it by the Blu-ray Disc player that can output the component terminal
and the video terminal at the same time (Substitution model name
example: BDP-S350).
However, please do the following signal output confirmation with
the oscilloscope beforehand when substituting it with the Blu-ray
Disc player.
