Cause

The color camera adds a chromanance component (color information) to the signal, also known as Chroma. This Chroma signal operates at 3.58 Mega-Hertz. The standard level for the Chroma is 40 I.R.E. units. When the Chroma level is low, the colors will be dull. If this level is too low, the color monitor will turn its color receiver off causing a Black and White only picture.

Resolution

The solution is to install a video equalizer in the line and adjust the color burst back to 40 I.R.E.units. If the Chroma signal is too high the picture will display color flaring and reduction of detail at the edge of the color flare.
