white dots on lcd screen for sale

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

Due to frequent use or poor quality, some parts inside the TV may move out of their position and cause white spots or 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 white spots or spots on the TV screen? White spots or spots on the LCD TV are the result of a dropped reflector (lens) inside the LCD TV panel. These reflectors are placed in front of the LED backlight and are used to spread the LED light across the screen. They usually fall out due to poor quality or the heat created inside the TV.

When you open the TV you will find a series of LED lights covered with reflectors or plastic lenses. These lenses are mostly glued in front of the LED backlight, and as the TV gets hot with use, they start to fall off their spot and create white dots or spots on the TV screen.

As we said above, these white spots or spots on the TV screen appear very often due to overheating issues and poor screen quality. Anyone who has paid attention knows that older TVs are practically unaffected by this image error.

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

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

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

To solve the problem of white spots on the TV screen, you will have to open the TV and with the help of the super fast glue you will have to put the fallen reflector back into place.

You will need to take apart your LCD TV and return the fallen reflectors to their original position with the help of glue. What you will need is the following:

If you already own an LCD TV or have decided to buy one, the testing process is identical. I always give it a try before deciding to buy a new LCD TV. New models may also have problems with white spots or spots.

During transportation or due to poor installation quality, the round reflectors can fall out of place and cause white spots. So to test a TV before purchasing and see if the image defect is present you can do a simple test.

Note! You can also press Pause during a movie when the screen is black to test the LCD TV to see if there are any white spots or spots on the TV screen.

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

When the spotlight or lens moves from its original position, these white dots appear on the screen. But in some cases, there may be more damage to the TV screen than a simple displaced spotlight or dead pixel, and it can cost you more than a new television.

Therefore, it is recommended to contact a specialist if you notice that the problem is not only with the displaced reflectors but something more. Please note that if your TV is under warranty, it is recommended that you contact a service center and let them take care of this issue.

This could mean that something isn’t assembled correctly inside of the phone and is pressing against your display panel. You can easily test this by opening the phone again and to not press it into the case. If you still see white dots it probably means that your display got damaged during installation or that it was damaged before installation.

I noticed something similar on an iPhone 7 Plus I worked on where the display flex cable was not correctly routed under the shield of the screen, causing some pressure on the screen resulting in similar white dots when touching on the display. Take a look at the screen replacement guide as of step 34 to double check your cable is routed properly. I’m saying this because the white spots in your pictures happen to match the placement of the ribbon cables.

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 .

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.

Hardware Failure In some cases, display issues occur due to hardware failure, such as with the video card. To rule this out, connect a second monitor, and then check for any display issues. If the picture on the new monitor appears properly, the problem lies with the first monitor. If the second monitor shows the same display issues as the first, your video card may have failed.

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.

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.

A different type of defect caused by microscopic contaminants within the manufacturing process can also be found. Contamination results in a dark "stain" covering one or several sub-pixels. They are not pixel or sub-pixel defects per say. No contamination is allowed under HP policy.

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.

I own a Dynex DXL32-10a lcd tv. I have it installed in my motor home and I use directv. I don"t subscribe to the directv hd service. My question is why are they white dots all over the screen? I was told that there would be some distortion on a HD tv without hd service but what should I expect? Is there anything I can to do make the picture clearer? At this point I cannot return the tv because it is past the 30 day rule. It still is under warranty however.

According to industry specifications, the diameter of a single defect spot on the screen must be less than 0.4 mm. The total number of defect spots must not exceed five. The diameter of a single spot must be less than 0.4 mm, and the distance between adjacent spots must be greater than 15 mm. In-warranty handling is not allowed in principle if the screen is considered to confirm with the standard.

If the screen defects exceed the specifications, back up your data and bring your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
