Green is missing from the area where you see the pink (actually magenta) spot. This might be due to a large amount of dirt on the green lens. It may be due to damage to the face of the green picture tube. You need to remove the front screen so you can look into the lens and determine that.

Depending on the make and model of TV, the screen may be held on by snap fasteners and come loose when you pull on the plastic bezel surrounding it. Or the bezel may pull off to reveal brackets screwed into the cabinet that secure the screen. Or there may be a trim strip under the screen that pulls off to reveal screws. Remove those and the screen will swing up and off.

Once you can see the lenses, clean them with a soft rag and glass cleaner. With the set on, look down into the lens and you can see the face of the picture tube. If you see a dark spot on the face, the tube is damaged and would need to be replaced
