Maye sure you are going to composite and not component
For instance
Composite should be
Red - Audio Right
White - Audio Left
Yellow - Video
Component would be video only(It does not have to be HD, but is more common with HD TV's) and NO audio. For audio you run the red and white audio cables or another audio source(Digital ect)
Green - Y = (brightness) and sync information.
Blue - PB/CB = difference between blue and luma (B − Y)
Red - PR/CR =difference between red and luma (R − Y)
They need to match on both sides
You CAN use the component cables(not run component into composite) for composite video/audio. just use the same colors on both ends.
