Help with my tv color

[sbfridinger]

Ok so my husband hooked up a surround sound unit but once he unhooked the cable box and got everything hooked back up the color of the tv is pretty much just black and white....please help!?!?!

Not enough details to be sure but if the cable box is hooked up to a shared component composite video input on the TV and the TV is set to component you get a BW picture. Check the TV menu and try setting the input to composite.
If the cable box is connected to the TV with HDMI then try rebooting the box.
