NoteIt is necessary to set the desired picture mode every time there is a change in the input mode, as the picture mode settings (brightness/quality) may differ depending on the Picture input (digital broadcasting, HDMI, etc.).
When only part of the Picture appears black and white or darkThis 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.
