My HD Polaroid TV is awesome, but the DVD attached to it only shows in black and white....anyone know why?

Question

The DVD player is functional ( we know that from attaching it to another TV)

There is also an HD receiver box from Comcast attached to it all

Settings on the TV all appear to be appropriate

Driving me nuts

Answer 1

When you connect via component, if you only connect Green, you just get black and white

Check the BOTH the Red and blue component connections.
