lcd panel white spot quotation
This MacBook Air took a very hard hit to the screen just to the right of the center of the display. The hit was hard enough to cause a white spot that was visible even after the cracked LCD panel was replaced.
The display was still mostly usable when the computer came in for screen repair, but many times cracks like this will get worse with time. I told the customer it was very likely to have a white blemish after I replace just the LCD panel and gave them the option of replacing the entire display for an additional fee if the white spot would bother them.
The customer asked if I would put a replacement LCD panel in and send them some pictures of the blemish so they could decide if it was worth the extra money to replace the entire display. These are the pictures of the white spot that was visible after the repair.
You can see the white blemish on the bottom left of the display. Different backgrounds cause the spot to be more or less noticeable. Usually, a background that is a solid light color will show the blemish more than a photo or other type of multi-colored background.
These spots are caused by the backlight sheets being marred by the hit that causes the LCD panel to crack. Basically, there are white sheets right behind the LCD panel that the backlight reflects off of through the LCD panel. If there is any damage at all to those sheets, you may be a white blemish in certain scenarios. The backlight sheet damage usually only happens when the hit that broke the screen was very hard and centered on a particular point.
As you can see in the pictures there are some backgrounds that really hide the white spot, while others almost show off the cosmetic defect. Overall the damage was not too bad and the customer decided they could ignore the blemish and would rather save the money on the repair.
White spots like this do not get worse over time, so if you think you can live with it, there isn’t a reason to replace the entire display except for cosmetic reasons. Everybody is different and some people can live with the white spots with no issues, while others really can’t stand them!
If you would like to know if I think there would be a white spot present after the repair, please send me a picture of the computer screen with a description of what happened that caused the damage. If the damage was caused by a twisting motion, there almost certainly won’t be any backlight damage. If the damage was caused by a hard hit or a hit with a sharp point causing the damage, the chance of a white spot is present.
If I ever see a white spot present during an LCD-only repair I take pictures and double-check with the customer to make sure they want to continue with the LCD-only repair. Most decide to just live with the white spot and are happy to spend less on the repair, but some do decide to go with a new display assembly instead and I am able to complete that repair as well.
Samsung TVs have led the global smart TVs market share for more than 15 years, with a number of great smart TV series having excellent picture quality, elegant design and great performance. However, like every other TV, they develop faults one of which is when there are white spots on Samsung TV screen.
In this guide, I am going to explain why you are seeing white spots on your Samsung TV screen. With that knowledge in mind, I will then show you 3 proven ways to fix the issue.
The LED diffuser lenses cover the bright LED light bulbs where they serve to diffuse the light from the bulbs uniformly across the TV screen.When they fall off, white light from the LED light bulbs shine directly through the screen.
The white light shining directly through the screen is seen as a white spot on the screen and is known as “orb”. Often, when this happens, more than one diffuser lens is dislodged and a number of white spots are noticed on the screen.
TVs have a backlight in the display panel which has white LED light bulbs equally spaced a few inches apart on equally spaced strips. Each light is covered with a diffuser lens, which diffuses the light equally in all directions to create a uniform bright light from all the bulbs.
These lenses are held to the backlight panel with an adhesive. Eventually, the adhesive can dry out or disintegrate causing one or more diffuser lenses to become dislodged. They may also become dislodged from impact or moisture in air. In the absence of the diffuser lenses, white lights from the LED bulbs shine directly through the TV screen.
If the white spots you have on your Samsung TV screen are circular and about 0.5-2 inches in diameter, then this is most likely the issue. In addition, if you move the TV around, you should hear the sound of the lenses moving around inside the TV panel which confirms that this is the case.
LCD TVs have hundreds of thousands of pixels, and can be more than 2 million of pixels on wider TV screens. For example, if the size of your smart TV screen is 1920 x 1080, then there are 1,920 X 1,080 (=2,073,600 pixels) on the TV.
Although, there are different types of defective pixels, what you have in the case of white spots on TV screens is the hot pixel (or bright dot defect). This happens when pixels whose transistors are “off” are stuck “on”, allowing light to pass through which creates a bright white pixel that is always on.
Finally, if the white spots are very tiny (about the size of a period), then you may have a faulty logic or main board. It could also be the T-Con board, although these are less frequently associated with white spots or dots on TV screens and more associated about horizontal or vertical lines across screen among other display distortions.
Depending on the reason and the situation causing the white spots on your Samsung TV screen, you may need to reattach dislodged LED diffuser lenses or replace the whole backlight array (LED strips). Finally, if you have a hot or stuck pixel, you can also fix that as well.
To fix a Samsung TV with white spots on the screen, you need to reattach the dropped LED diffuser lenses back on the LED lights. To do this, you will need to open up the back of the TV and access the display panel.
Repairing dislodged lenses require opening the TV and disassembling the display play which is quite a delicate part. However, the step-by-step procedures below should guide you in reattaching the lenses and fix white spots on your Samsung TV screen.
In addition, if you use the wrong type of glue, it might burn the plastic lens eventually which will take you back to seeing white spots on your Samsung TV screen.
Like I explained earlier, a hot pixel is a defective pixel which remains constantly on, rather than cycling on and off like other pixels do. When this happens, the pixel can show up as a bright white dot and this happens even on recent Samsung tizen OS smart TVs.
In most cases, to fix a Samsung TV with white spots or dots on screen, the dislodged diffuser lenses need to be reattached or you need to replace the whole backlight array. Reattaching the diffuser lenses should cost around $50, while replacing the whole backlight array should cost around $100 for the replacement array plus service charge.
I figured out what"s causing the white dots on the screen. It has to do with the silver, rectangular box that"s on the ribbon cables. If you fold the ribbon cables up tight on the back of the screen before covering them with the heat shield it causes the silver rectangle box on the ribbon cables to be too high, therefore it"s pressing against components in the rear casing when you put the front and back back together. You have to leave a little slack on the ribbon cables when you fold them up and before you tighten the screws on the heat shield. There"s an opening in the rear of the phone that"s purposely left vacant where this silver, rectangle box should be falling into when the two halves are put together . You may have to play with how much slack you leave on the ribbon cables a few times to get it lined up properly. But once you figure out exactly how much slack to leave and where to line up the silver, rectangular box then you"ll never have the white dot problem again. Keep in mind also that the iPhone 7 and the iPhone 7 Plus are a bit different. So you"ll have to experiment with each one separately.
Bright or white spots are a big problem with tv screens, especially on Samsung. And yet, even their formidable LCD tv screens are vulnerable to one of the most annoying TV problems: white spots.
Setting up your LCD TV can be a lot of hard work. From mounting it away from annoying glares to adjusting image settings to be most pleasing and easy on your eyes, you want to make sure that you can properly relax for your hours of entertainment.
You also want to make sure that you’re not overworking your TV. Those white dots flashing on after you’ve powered up your set can be a serious distraction, especially when they beam over darker images.
You might not be wrong, but in the case of roughly three small, white circles on the side of your screen, if not more than a dozen throughout, the problem may be deeper.
The repair costs for a Samsung TV with White Spots would usually range anywhere from around $200 to $300. This is quite pricey, so make sure you read through the whole article before you get it repaired.
This might not even solve your problem, as there could be more serious LED damage behind the white dots. If you want to play it safe, calling a technician may be more cost-effective.
The white spots on a TV are most likely stuck pixels. This usually isn’t that serious of a situation and can be dealt with through serious troubleshooting.
There is a common misconception that white spot pixelation issues in Samsung TVs stem from LED reflectors. This can also cause lines on your Samsung TV.
There are also fewer technical reasons for white spots, both in software and in hardware. Regarding the former, you can relax the processing power of your TV by adjusting image settings.
Most people would just see white pixel-looking things on their screen, but a few users have been reporting that they have seen white spots on their Samsung TV as well.
White spots on your tv usually happen because your tv has been hit in a certain area. If you can think back to a time when something hit your tv or if this happened just now, then this explains it.
But then, we all also know that we should be flossing our teeth regularly. Of course, as with black spots on your teeth, white spots on your TV screen can mean getting invasive with your upkeep.
You may have to use a cotton swab very lightly to remove some of the more stubborn spots. After you’re done cleaning, carefully put your TV back together.
Just for good measure, give the front of your screen a good cleaning as well. Feel free to be more vigorous than you were with the back, but still be careful with this highly sensitive equipment. If the white spots are still there, then the issue is more than cosmetic.
Backlight replacement service may only cost $100 or so. You can check by removing your TV’s screen and the white diffuser sheets separating it from the LED light array.
The more common cause of this issue in Samsung’s competitors is problems with LED light reflectors. If you have an LG LCD TV, for example, then maintenance on stuck pixels can be easier.
LED reflectors are small bulbs that redirect an LCD TV’s backlight to illuminate an image. Without them, the light is directed forward, thus resulting in small lapses in the image’s pixelation.
Again, though, this is considering that your issue is stuck pixels. If you are dealing with black spots, you cannot simply follow the previous instructions.
Black spots on your TV may be a much more serious issue. At best, it means that your TV screen has accumulated an excess of debris from exposure to the elements.
Even dirt on the surface of your screen can gradually erode pixelation, so be sure to clean your TV regularly. The more likely, more extreme case with black spots is dead pixels caused by power connection failure.
If the spots are due to stuck pixels, then a screen replacement may be needed. It is hard for a consumer to track down a replacement screen, contact Samsung’s repair services or a local independent technician for a quote.
Disassemble your TV carefully, as if you were replacing the screen, and gently glue these reflectors back into place. Of course, if you are dealing with black spots, then you are probably dealing with dead pixels.
Hey guys. Took the laptop into the Apple store today to have them look at it. They saw the spot and agreed it was a defect. They called up Apple Care for me and setup a case number with some notes affirming that there was an issue with my display.
So I purchased a 4k 65" Samsung in 2016. right about 2 years later I noticed a white spot on the screen, just a little right of center and about 6 inches from the top. I contacted support and the tech tried to tell me is was due to external damage! I called back in and asked for a supervisor. Worked with him and we defaulted the settings and still had the spot. I was informed that with only a 1 year warranty that the repair would be billable. I should have purchased the extended warranty but based on other samsung products we own, I didn"t feel it necessary. Boy, was I wrong. Now, I have 3 white dots in a row heading down the screen and jusy saw that I have another on the bottom.
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.

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.
Liquid crystal display (LCD) is a flat panel display that uses the light modulating properties of liquid crystals. Liquid crystals do not produce light directly, instead using a backlight or reflector to produce images in colour or monochrome.
How much does it cost to fix a white spot on a TV? The average cost for fixing a white spot on your screen is $79-$169 in the United States, and if that’s what you’re dealing with, then either call an expert or visit some local shops to get more information about this issue.
White spots (or dots) on the TV screen are the result of a damaged processor and the overheating process during warm summer temperatures. Another reason that can be the cause of white spots on the TV screens is spikes or surges as electricity supplies can vary throughout the year.
Sometimes, if some of the pixels are broken and stuck to a particular state that causes the problem, they appear as white spots on the TV screen. To solve this problem, you must open your TV and use the super glue stick that falls back on the reflector where it belongs.
White dot on your LED TV screen are due to fallen reflector. On top of every LED in LED array of your TV, there sits the reflector. If its fallen off from its place then the light is directly pointed to a single spot.
The lifespan of flat-panel TVs is approaching 100,000 hours. The lifespan of a liquid crystal display television is longer than that of a similar-sized television.
When the DIFFUSER LENS becomes dislodged from the LED light (by either an impact, or due to “old age”), the diffuser lens falls to the bottom inside the LED panel. This creates a bright light in a single spot on the display panel.
Dead pixels are either black or white all the time, regardless of what’s on the screen. White pixels are actually called “hot” pixels, but they’re principally identical to dead pixels. If you determine that your monitor has a dead pixel, you’ll need to either take it into a repair department or replace the screen.
A dead pixel is a permanently damaged pixel that does not receive any power, which often results in a black spot on the camera LCD. … Simply turn on Live View and point your camera at a bright area such as the sky. Dead pixels will always show up in the same spot even if you move the camera.
It is usually advised to buy a new set if your backlight panel needs a complete replacement unless it is still in warranty. To repair the backlight panel it may cost you around Rs. 5000 to Rs. 25000, including replacement parts and labor.

More importantly, you can do so without having to worry whether or not you have to buy a fully new TV! If your TV panel is still in one piece, meaning a brick hasn’t gone through the screen there is a good chance it can be repaired!
I have tried taking pictures at dark and I saw that I couldn"t see the spot in the picture, at least if there, wasn"t visible to me. I don"t like the one spot, especially if i take pics at night but if it doesn"t hamper the picture quality, it should be okay, right?
