Spot remover. Black marker? Maybe not. (;^D).
Really, if it's just a little white dot on the screen, it may just be a bad pixel. Those things happen. The manufacturers warranty against more than 'so many' bad pixels, but if there's just one, I doubt they would replace it. If it's a big block of white, you might be able to get it replaced.

You may have bad pixels. What type of TV is it?

could be a dead pixel you can some times get them back by tapping the pixel with the stylus off a nintendo ds have the tv on a white screen when doing it so you can see when it has worked. need to tap just the pixel square do it to each pixel.

Could be whats known as dead pixels, this is tested be showing up a black or white screen. Microsoft paint or word will do. If an area always has dots then dead pixel. However if it doesn't constantly remain a dot then, some-thing else. Dead pixels come about due to age.
A technician will be able to diagnose your problem by performing white screen test.

It sounds like your colour sensor is having issue deciding what colours should be what. To test this, take a picture of something else white, first try something large like a cloud or a white pillow from close up, see if it comes up black. Then try something like an egg against a different colour background, something skin toned would work best, or use yellow. If those come up white, you've got me stumped, but it is likely they will appear to be black.

There's a 'data control' and/or 'address' problem that's developed. Pixels depend on voltage, control, and data coming too their designated address.

A digital circuit feature called a 'DATA_ADDRESS_ BUS" are responsible for 3 criteria: Delivering voltage, control, and data to each pixel in less than a second.

1) If voltage fails the pixels don't light up. They appear black in color (their 'off 'state)....numerous pixels that don't light up look like a black line. But their actually individual pixels with no voltage.

2) If control fails then all pixels are white in color (their 'on' state). Without control the pixels can't adjust properly to high or low 'state', meaning brightness and dimness. This looks like a white line vertically on the screen.

3) If data fails then the pixels can't adjust to the proper color at the proper time.
This appears as a line that changes color out of sync with the entire picture.


Have a technician look at the pixel address registry circuits. As well as control and linear circuits....the problem is somewhere in there!

Try to set your TV to factory default setting.

I had a similar problem with my LG plasma. I used the Image Sticking Minimization
(Pixel Orbitor, White Wash, and Inversion) feature which is designed to prevent image burn in and ghosting. This ISM feature may be available on the Samsung or any other brand under a different name. I activated the "white wash" option for about 30 mins, the screen turns white and somehow the pixels get reset. The green noise disappeared after that.
I hope this helps. Phezbuster

The half picture is a verticale problem. This is difficult to repair. Send to a repair shop.
