Red afterglow
I have been noticing a really odd effect on my TV. I have noticed that if I have a color bar pattern on the TV, and cut directly to a black screen, the black level has a slight reddish tint to it, but after about 20 seconds it goes back to a neutral grayish black.
Is this an optical illusion, or can there be something electrical causing this freaky effect? |

Screen phosphors can have different persistance rates. After running the red hard and then suddenly cutting off some "afterglow" can occur. Perfectly normal.
