Joe, I had this problem after I got my CI back from AVSource for a hardware upgrade. The color from component input was intermittent (sometimes it was there, sometimes it wasn't; I had to turn the unit on and off several times for it to regain color). On Alan Gouger's advice, I opened the CI and tweaked the color pot inside. It is the white pot toward the back of the unit. YOU DO NOT NEED TO MOVE THIS VERY MUCH!! I barely touched it and color snapped back on and has been rock solid ever since (a couple of months at least).
Good luck!
Dave
