When a pixel goes on the screen can it get any worse

yes it can but its not like bacause one pixel got dead another will follow . Dead or half-dead pixels are the effect of a panel aging or a miscalculation in the creation of the panel .

Dead pixel repair

Hi Tasha,
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.

Red and pink dots on the screen Samsung plasma tv

I can't see the points on the video. However, I think you are talking about dead pixels. I'm afraid dead pixels can't be repaired.

My 1080 HD tv has green pixals on the screen. They are not burned in they move.

These pixels are know as dead pixels and are not covered under warranty, in fact most manufacturers expect them and set a certain number of acceptable dead pixels before the screen is classified as faulty. There is no way to get rid of these dead pixels I am affraid to say. If the seem to move randomly all over the screen then this could mean that the logic for the screen is on its way out and as this is an integral part of the LCD module means replacing it would be extremely costly.

Red and green stripes (1" wide) running down the screen. Started with one red, now a green and another red. The stripes come and go at times, but most of the time they are present.

I hate to be the bearer of bad news but this is actually one of those known and predicted issues with LCD televisions. What these are called are "dead" lines of resolution aka dead pixels aka frozen pixels.
This is one of the flaws of LCD televisions, there is a completely random, unpredictable fail rate of LCD pixels in all panels, the likeliness of failed pixels varies depending on the quality of the panels used in the TV.
There really isn't a resolution to make them go away, if they are simply frozen, usually a light (VERY LIGHT) tapping of the screen at the top and bottom points of the line will refresh the pixels. If they are coming and going more often, it means that the panel is weak or malfunctioning in those areas and you need a new panel in the TV. Unfortunately it's quite an expensive repair, running at least $400 USD, if you are within warranty period (usually only 3 months for dead lines of resolution.. but it varies up to 12 months depending on the manufacturer) I would suggest calling Vizio and inquiring about a replacement TV. They generally won't allow a repair as it costs them less to simply give you a new unit all together.
My apologies for your bad luck!

Why are blue dots appearing on my Sony Flat screen tv. they seem to multiply every day.

If the dots are tiny, those are probably dead pixels. The circuitry that drives them is probably degrading over time for some reason. It's obviously defective, dead pixels happens a lot with LCD screens. I would hope it would be covered by warranty, because the only way to fix dead pixels is replacing the screen.

Toshiba regza lcd 46x3500

This is what is known as a dead pixel. If you have a standard wide screen lcd monitor it has over 1 million pixels. It is not super un-common for one to go bad. It will either always be dark or in your case always be lit. It is not worth it to repair, and in most cases unless you have multiple dead pixels with in a square inch of screen, it is not covered under warranty either.
Each pixel is individual and the problem will most likely not spread.
