blue spot on lcd screen factory

If you’re someone who is an avid TV user then you may have come across a problem where you see tiny blue dots on your TV screen which may have had you in confusion as to what caused them in the first place and how you can get rid of them to get back to watching TV on a flawless screen.

Don’t be concerned if you detect blue spots or dots on your television. This issue is known to occur on the majority of LCD TVs and is really simple to resolve. The blue specks (dots) you see are the light from your TV’s LED backlight.

Some pieces within the TV may migrate from their original location as a result of repeated use or poor quality, causing blue spots or dots to appear on the screen.

What you may be seeing is one or more of the more than 2,000,000 dots that make up the LCD or OLED screen’s composition. These dots (sometimes referred to as pixels) might be red, green, blue, white, or black.

To maintain a high quality of operation, these LCD/OLED screens are manufactured using high-precision technology. However, regardless of the manufacturer, there may be a tiny number of dots that do not change color on all LCD/OLED panels. This is a common phenomenon with all LCD/OLED screens from all manufacturers, and it is inherent in the technology. Most of the time, these dots remain on the screen but are only visible when an all-white or all-black image is displayed and should not be seen under normal viewing conditions.

If your TV screen has blue spots, it might be due to a manufacturing flaw in the blue LED backlight. In this situation, you will need to change your backlight.

Sometimes the blue spots may appear in a purple tone too and these purple-colored spots are created by the HDMI cable connection from the cable box. These purplish-blue hue spots can be removed by doing the following steps:Check that the HDMI wires are securely hooked into or linked to your TV.

Whether or not you have previous experience repairing TVs or electronics, I believe you will be able to fix your TV and remove the blue spots on your TV screen if you follow the directions below. You’ll need to unscrew your LCD TV and use glue to reattach the fallen reflectors back into position. All you need to do is just follow the following steps and you’ll be able to fix this problem without the need for help from a technician.Turn off your television and unplug it from the power supply.

To add adhesive to the Q-tips, use them. (Apply glue around the area where the reflector has fallen) After applying adhesive, set the reflector in position and hold it in place until it is squeezed.

The issue of blue spots or dots is not new, and it can show on practically any LCD or LED TV, whether brand new or secondhand. We have previously stated in this post that this problem is simply fixed and that you do not need to be concerned.

Keep in mind that if your TV is still under warranty, you should call a service facility and let them resolve the situation. They have greater knowledge of these kinds of issues and will repair your TV for free.

You can unscrew the TV to examine whether the reflecting lenses have come loose, and then use super glue to reattach them. If you believe you won’t be able to solve the problem on your own, contact a TV service specialist and delegate the task to him. I hope we were able to assist you in some way and that you were able to fix the problem with blue dots.

I have an iPhone 6 which I did a screen replacement for. When ever I snap the screen onto the phone fully and put some pressure on the screen-- blue/purple marks show up. There"s one in particular that shows up right above the home button and appears when there is a slight pressure applied on the bottom part of the screen. Pressing the home button with more than just a finger nail triggers this too. So now, whenever I press the home button, the mark appears.

I have tried to see if there is anything under the screen causing this and I couldn"t find anything. I attached the screen to a different iPhone. The problem was still there, the marks showed up in the same place too.

I ordered a second screen from the same company, and it also had the same problem with the marks in the same place. Albeit, the new one didn"t have marks that were as dark as the other. But they both only had this problem when the screen was snapped into the iPhone. When it"s detatched from the iPhone, it is completely fine--no marks appear from pressure.

I had my screen repaired recently and they had to exchange the entire display. They charged me ~88€ including shipping. (I live in Germany and had to ship my device to Poland). I don"t know what the costs are in other countries/continents

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.

If you see odd dots on your screen and you"re absolutely sure they"re not dirt, the first thing you should consider doing is to check if these dots are stuck or dead pixels.

There are three different modes to test your monitor into. Click HTML window to test for stuck pixels. Press F11 to toggle full-screen. You"ll see a range of different shades of grey. If you move the mouse to the top of the test window, a menu will appear. Click on Homogenuity and go through all the colours from the list.

If you find something out of ordinary, then open Launch JScreenFixat the bottom of the page, and it will open a black browser window with a square of flashing pixels. Press the green button in the bottom right corner to go full-screen. Drag the flashing square to where you found the stuck pixel and leave it there for at least 10 minutes.

That annoying dead pixel on your TFT, OLED, or LCD screen might just be stuck and easy to fix. We"ll show you how to do it. You can still return your monitor if this doesn"t work; nothing we recommend here will void your warranty.

Yes, you should test any new monitor for bad pixels. You can simply run your screen through a palette of basic colors, as well as black and white in full-screen mode using a tool like EIZO Monitor Test.

EIZO Monitor Test is an online tool that lets you find and eventually fix stuck pixels. It packs many options into a single test window, but it"s easy to use once you have an overview.

To test your screen, check all the boxes you want to include in your test. We recommend the default setting of having all boxes checked. If you"re testing multiple monitors, you can open the test on an additional monitor. When you"re ready, click Start test to launch the full-screen test window.

Below you see the first test pattern. Each screen has an explainer in the bottom right detailing what you should look for. Next, you"ll see a menu that lets you go from one test to the next on the left. Move through the black and white screens and all the solid colors (green, blue, and red) and check our screen. To exit, press the ESC key or the exit symbol in the top right.

This is a very thorough test not only meant to identify bad pixels but also powerful enough to test the quality of your monitor. Unfortunately, with Flash no longer supported by most browsers, you"ll probably have to use the executable version to make it work.

Move the mouse to the top of the test window, and a menu will appear. There is an info window that you can turn off with a button in the top right corner of the menu. Then click on the Homogenuity test point and move through the three colors as well as black and white.

Fingers crossed, you won"t discover anything out of the ordinary. In the unfortunate case that you do, let"s see whether it"s a stuck or a dead pixel and what you can do about it.

A stuck pixel, sometimes wrongfully referred to as a hot pixel, is defective because it receives incomplete information. Hence, it appears in one of the colors that its three sub-pixels can form, i.e., red, green, or blue. Strictly speaking, hot pixels only appear in digital cameras when electrical charges leak into the camera"s sensor wells. Sometimes, stuck pixels fix themselves.

The tool will load a black browser window with a square of flashing pixels. Press the green button in the bottom right to go full-screen. Drag the flashing square to where you found the stuck pixel and leave it there for at least 10 minutes.

UDPixel, also known as UndeadPixel, is a Windows tool. It can help you identify and fix pixels using a single tool. The program requires the Microsoft .NET Framework. If you"re not on Windows or don"t want to install any software, scroll down for the online tools below.

Should you spot a suspicious pixel, switch to the Undead pixel side of things, create sufficient amounts of flash windows (one per stuck pixel), and hit Start. You can drag the tiny flashing windows to where you found odd pixels.

The PixelHealer lets you flash a combination of black, white, all basic colors, and a custom color in a draggable window with customizable size. You can even change the flashing interval and set a timer to close the app automatically.

Let it run through all colors in Auto mode to spot whether you have any weird pixels on your screen. If you do, start the fix, which will rapidly flash your entire screen with black, white, and basic color pixels.

Should none of these tools resolve your stuck or dead pixel issue, here is one last chance. You can combine any of the tools detailed above and the magic power of your own hands. There is a very good description of all available techniques on wikiHow. Another great step-by-step guide can be found on Instructables.

This works because, in a stuck pixel, the liquid in one or more of its sub-pixels has not spread equally. When your screen"s backlight turns on, different amounts of liquid pass through the pixel to create different colors. When you apply pressure, you"re forcing the liquid out, and when you release the pressure, chances are the liquid will push in, spreading around evenly as it should.

When all attempts to revive your bad pixel fail, the next best thing you can do is to make peace with it. One ugly pixel won"t break your screen, and eventually, you"ll forget about it. If the defect affects more than a single pixel, however, or just bothers you a lot, you can always replace your monitor.

First, check the warranty. The manufacturer or the marketplace where you purchased the monitor might cover dead pixels. Note that most manufacturers define a maximum number of allowable bad pixels for specific resolutions, and the warranty won"t apply until your monitor crosses that threshold.

Bright or dark sub-pixels can occur during the production of the LCD Monitor panel but does not affect the LCD Monitor functionality. The customer may notice the bright or dark spots if the film of the liquid crystal does not perform as expected while customers uses the LCD monitor. However, this is not considered a defect unless the number of bright and dark subpixels exceeds the maximum allowable threshold (...)

On a monitor with over 12 million pixels (Wide QXGA+, 2560x1600 pixels), for example, LG"s pixel policy says that 12 bright or dark sub-pixels is the maximum you have to tolerate.

Should all of these approaches fail to fix your dead pixel warrior, at least you"ll now know it"s not simple to fix, and, you might actually have to replace the screen.
