Question about Televison & Video
If this is a projection TV set, it is possible that there is some dirt in the lens system. If the dot is pink, it is most likely the dirt is in the path of the green. In projection tube sets, it is also possible to have a burn spot on the phosphor of a tube.
If your set is a direct view set such as a liquid crystal, or a plasma, or a flat panel, this can also mean a dead pixel on the green. Dead pixels cannot be revived.
Depending on the particular nature of the fault, you will need an experienced TV service tech to service your set.
