When only part of the Picture appears black and white or dark
This symptom is not because TV is a defect, but rather because fighting channels (i.e. UFC channel), frequently show scenes that are graphic or have excessive bleeding.
To overcome the reluctance to watch, the area is therefore handled in black and white.
The same logic applies to some channels where scenes show up in mosaic patterns.
