Black and white output on analog

No I dont think a defective cable could cause no color but you never know in this world of wacky electronics.. I would first check in the menu and see if theres a video output mode and make sure its in the mode that your tv is Like pal seacam or ntsc.. if this is all in the norm then i would say that you have a croma demod problem in your dvd player and unless you have a scope and a print showing where the croma couples to the video then its time for a pro BUT if it works on the RGB output then you really dont need the video output.
