Re: Component Video Sync Problem

NTSC Component, by definition, contains all you need to lock up a monitor in the three signals.

from WIKI:
Component video is a video signal that has been split into two or more components. In popular use, it refers to a type of analog video information that is transmitted or stored as three separate signals. Component video can be contrasted with composite video (NTSC, PAL or SECAM) in which all the video information is combined into a single line-level signal. Like composite, component-video cables do not carry audio and are often paired with audio cables.
When used without any other qualifications the term component video generally refers to analog YPbPr component video with sync on luma.

RGB, on the other hand requires a fourth cable supplying sync.
from WIKI:
RGB requires an additional signal for synchronizing the video display. Several methods are used:
composite sync, where the horizontal and vertical signals are mixed together on a separate wire (the S in RGBS)
separate sync, where the horizontal and vertical are each on their own wire (the H and V in RGBHV)
sync on green, where a composite sync signal is overlaid on the green wire (SoG or RGsB).
