SOURCE: RCA tv only in black and white?
The route through the circuits in the TV from the various sources all lead to the final video amplifiers for red green and blue. Somewhere along the route is a circuit called a colour switch. This allows colour if the signal is strong enough, otherwise it only allows black and white. This fault suggests a weak video chip which is the one just before the switch circuit. the fault could also be a faulty coupling capacitor to or from this chip, or a low power supply voltage. Check for dry soldered joints around this circiut. Please note if resoldering on new televisions that they may have non leaded solder which requires about 50 degrees centigrade hotter iron.

There some thing that you had done to get black and white on your tv with the dvd ,check your connections.if the connections are properly connected then the tv could be having a problem in the video input, have a tech look at it.

Wow that's interesting, was there anybody watching your home while you were gone? There is a possibility that someone simply turned down the color level with the color control? Check that first. It's an unusual symptom. With composite video, component video or HDMI it's not usually possible to experience that defect. Since the color (chrominance signal) is usually inseparable from the luminance (black and white signal) I would check the color setting first. Other wise your set has become unable to detect that color signal... I bet it's a setting rather than a defect.
