Why is my DVD player in black and white?

There are several possibilities here. One is that you’ve not connected the cables properly; check that the cables match the color coded jacks they’ve been attached two. The second possibility is that there is a fault with the chroma signal due to either the connections or chipset having a fault. The third possibility is that the color saturation on your display has been turned down to black and white by mistake––unusual but worth checking. Or, finally, you may have inserted a black and white DVD, somewhat common with older TV shows and movies that you expected to be in color or colorized but were not.
