If you find yourself in a situation where you notice spots or white spots on your TV screen, don"t worry. This problem is known to occur on most LCD TVs and is very easy to fix. The white spots you notice are the LED backlight inside the TV.

Due to frequent use or poor quality, some parts inside the TV can get out of position and cause spots or white dots to be projected on the screen. In this article we will explain why this problem occurs and how to fix it. So let"s get started.

So what are the causes of spots or white spots on the TV screen? Spots or white spots on the LCD TV are the result of a reflector (lens) falling inside the LCD TV panel. These reflectors are placed in front of the LED backlight and are used to diffuse the LED light across the screen. They usually fall out due to poor quality or heat generated inside the TV.

When you open the TV you will find a series of LED lights covered with plastic reflectors or lenses. Most of these lenses are glued in front of the LED backlight and as the TV heats up with use, they begin to fall out and create white spots or blotches on the TV screen.

As we said earlier, these dots or white spots on the TV screen appear very often due to overheating and poor screen quality issues. Anyone who has been paying attention knows that older TV sets are practically not affected by this picture error.

This problem is mainly found in TV sets with LED backlighting, more precisely the so-called LED side backlighting. Behind the panel is a light-conducting plastic plate.

Dead pixel: every LCD and LED TV is composed of millions of pixels or dots whose main purpose is to illuminate and produce the image on the TV screen. Sometimes, the problem may occur if some pixels are damaged and get stuck in a particular state that is causing the problem and appear as white dots on the TV screen.

LED Reflectors: Every LCD TV is equipped with a reflector (lens) that helps to facilitate and diffuse the LED light on the screen. Sometimes, these bulbs become loose and come out of place. When this happens, you will notice the bright white spot on the TV screen. In most cases, you will have several white spots or spots on the screen, not just one.

To fix the problem of white spots on the TV screen, you will need to open the TV and with the help of super fast glue you will need to replace the fallen reflector.

During shipping or due to poor quality installation, round reflectors can come out of place and cause white spots. So, to test a TV before you buy it to see if the picture defect is present, you can do a simple test.

White spots (dots) on the TV screen are a very common problem with LCD TVs. Almost all LCD TVs work with a small chip made up of millions of tiny mirrors. Each mirror is like a dot or pixel on that screen.

When the focus or lens is moved from its original position, these white dots appear on the screen. But in some cases, the TV screen may suffer more damage than just a shifted spotlight or a dead pixel, and it may cost you more than a new TV.

Therefore, it is recommended that you contact a specialist if you notice that the problem is not just with the shifted spotlights but something else. Note that if your TV is under warranty, it is recommended that you contact a service center and let them take care of this problem. They have more experience with this type of problem and will fix your TV for free.

Anyway, the front and back of the LCD probably have several thin, transparent plastic sheets in front and behind it. Some of those sheets got creased, somehow. The repair is to obtain new sheets to replace the old ones, as they"re like paper, where creasing is permanent. You might have to find a screen repair shop, or contact the manufacturer, or hope google can find a seller.

My laptop"s (Dell Latitude D630) LCD screen turned black but the system is running fine.  I purchase a replacement LCD screen and now it has a large white spot at the bottom right of the screen at the login screen.  Then after I login, the white spot moves to the left hand side.  So I reached out to the vendor for another replacement, but once I put the screen in, the white spot is on the same area at login and after logging in (see attachements).  I know the hard drive and o/s are fine b/c I connected a monitor and everything looks great.  So I"ve ruled out that the LCD screen is not the cause...now what?

If you find yourself in a situation where you notice white spots or dots on your TV, don’t worry. This problem is known to occur on most LCD TVs and it is really simple to solve. White spots (dots) that you notice are the light from the LED backlight inside your TV.

Liquid crystal display (LCD) screens are made up of millions of small colored spots called pixels. A small white spot on the screen is called a white pixel. This white spot is also known as a stuck pixel. Stuck pixels can appear on any LCD screen, including laptops, monitors, and cell phones screens.

Common causes of a white pixel include a malfunctioning transistor or uneven distribution of liquid inside the LCD monitor. Each pixel has three sub-pixels in red, green, and blue. Transistors carry electric current to the sub-pixels. The current makes the pixels change color.

If a transistor shorts out or remains open, the result can be a white, red, blue, or green pixel. If the pixel is not getting any current, then a small empty black spot surrounded by white space may be seen on the LCD screen. The black space is called a dead pixel.

Sometimes, a white pixel can be repaired. Various software programs are available that may find and fix white pixels. Generally, software can run a complete pixel test, or search by pixel color to find a white pixel. Software can take anywhere from 20 minutes to a few hours to test all the pixels.

Rubbing or tapping the screen may also repair a stuck pixel. Users can try to repair pixels at their own risk. Care must be taken when attempting to repair a pixel by tapping or rubbing the screen. It is possible to break other pixels surrounding a white pixel.

Monitors should be turned off prior to rubbing or tapping on the screen. Placing a damp cloth on the screen may help prevent scratching and further pixel damage. The screen can be turned back on while still applying pressure to the screen. Users can then remove the pressure and the cloth to see if the white pixel has been repaired.

White pixels may also start working over time without any attention from the user. Some white pixels appear only after several hours of continued use. Generally, white pixels are an annoyance and do not stop the screen from working properly.

Manufacturers each have their own pixel policy regarding LCD screen replacement. Companies rarely replace monitors with a single white pixel. Users can check their warranty information to determine how many white pixels are required before the manufacturer will replace a screen under the original warranty.

try running solid collors. if bios/diags have a lcd test see if it shows up at any time when that runs. I have seen some dammage where either a thumb print etc only shows up when the screen doesnt have a picture on it. as soon as the backlight turns on during boot or switching modes. some you can faintly see when solid color backgrounds are used and a specific color is chosen.

I would suspect its phisical damage to the display some never get worse if that is the case and others eventually get larger and more pronounced. we see both cracked lcds and "water marks" when stabled documents or other objects get left in the laptop when the lid is closed.

I had a ASCEND MATE 7 for a while and after about two months got wild white patches on screen, sold it by the way and bought a new one. This new one even had brighter patches from the beginning!

I think this is the problem with internal batteries, as they are poor quality and after some time of use the battery"s pressing against the back of the LCD ... and the whites appear

Short for picture element, a pixel is a single point in a graphic image. HP TouchSmart PCs, All-in-One PCs and LCD flat panel monitors display pictures by dividing the display screen into thousands (or millions) of pixels, arranged in rows and columns. The pixels are placed close together so that they appear connected.

A full pixel defect is a bright white dot or very noticeable black dot on the display. No full pixel defects are allowed per HP"s monitor specification.

Bright sub-pixel defect - In this image, a bright spot on a black background is caused by sub-pixels (in this case, a red sub-pixel) in the "on" state.

Debris trapped within the LCD structure can result in dark spots, but under magnification these are distinguished from an "off" sub-pixel, as the shape of the contaminating particle is visible.
