Question about Samsung UE40B7020 40 in. LED TV
Unfortunately, repairs at the "pixel level" are not possible. The display is an "all or nothing" type of repair (I'm not talking about the back lights and support electronics - I'm *only* talking about the display screen). That means that the entire screen is replaced if there are to many dead pixels. (Most screens have dead pixels - manufacturers limit the number of dead pixels on a screen that can be assembled to a TV). If it the Quality Assurance people in the factory find a number of dead pixels that is less than a certain amount - it is "good" and ships. If it is more - it is scrapped.
Generally, your options are: live with it, replace the screen or buy a new TV.
