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.

Thanks guys! I just replaced the leds for my tcl 55 inch tv and after bout a week I started seeing the bulbs on the left side of the screen. Since the tv was an awesome find and the bulbs were like 30 bucks on eBay I’m fighting the inevitable being going back in and fixing that plastic deflector post. The screen is extremely fragile so if u don’t wanna pay 14 bucks at Home Depot for them window suction cups that were well worth the money For loners like myself lol, make sure u get another person to help u with the screen panel once it’s been dislodged . Especially if it’s a big honker. Nothing more scary than popping it out by urself and get stuck in a very bad situation as in u can almost hear the crackin of the screen Or knowing that I’d u take one more step this here screen will crack .

so disappointing with Samsung and my 65 inch TV. Only 5 years old and I have white spots on my screen. After doing some research I find it is because some of the filter lens have come un glued causing the LED light to shine through. This is clearly due to poor workmanship. I called Samsung and they tell me sorry you are out of the warranty period. Would you like to buy a new Samsung TV, we got some great deals for loyal customers. First why would I buy a new Samsung TV when you do not make a quality product. Second the price quoted was the same as at Best Buy. So no big savings. I have a Sharp TV that is 15 years old with a perfect picture. I wanted a smart TV and thought I purchased a quality TV but now I know I did not! Make it right Samsung send me a new TV that works.

All HP and Compaq notebook LCDs adhere to strict quality and reliability specifications. A small percentage of LCD panels may have minor cosmetic manufacturing anomalies or irregularities such as bright or dark dots in the viewable area. These cosmetic imperfections are common to all LCD panel types and are not specific to any HP model or product line. For more information please refer to this HP article.

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.

Display issues with your computer can make it hard or impossible to use your machine. If you see odd behavior coming from your screen, reboot the computer to see if the issue resolves itself. Should the white spots and black background reappear, it could mean that your computer has pixel problems or screen damage.

Hot Pixels Your computer"s LCD screen is comprised of thousands of tiny pixels, which cycle through three basic colors -- red, green and blue -- to create images. Sometimes a pixel can get stuck in the "on" position, and appear as a white dot. This is known as a "hot pixel," and you may be able to get it unstuck by using pixel-fixing programs such as Undead Pixel, JScreen Fix or Stuck Pixel Fixer (see Resources). Hot pixels have defined edges and are either square or straight lines.

Screen Damage If the white spots on your screen are larger than a few pixels or are irregularly shaped, your screen may have suffered some sort of damage. Examine the screen for signs of cracks or liquid entry. Damaged screens aren"t repairable, so you need to completely replace yours if it"s damaged.
