Unfortunately it would appear that your pixel is "dead". Your screen is made out of several million transistors, 3 for every pixel. If one of them fails you will obtain that small point on your screen. There is nothing you can do. Warranty woun't cover this because based on international regulations you need to have at least 5 subpixels (transistors) broken in order to comply with in warranty repairs. In terms of manufacturing companies one dead pixel is an "unfortunate accident" but not one compliable with warranty conditions. You can't do anything except changing the whole display unit, because the damage is permanent to that particular pixel. Sorry for delivering the bad news.

Why the white or black spot on LCD Display


Dead and Stuck Pixels <br /> Pixel defects for an LCD monitor are defined as one of two types: dead or stuck. Technically, both types of pixel defects are stuck pixels but it really deals with the electrical currents and the state of each pixel or sub-pixel. <br /> A dead pixel is defined as a pixel or set of sub-pixels that has failed and is permanently in the off position. This condition means that the pixel will not let any light through. This can be observed as a dark or black spot on a brightly colored or white background. <br /> A stuck pixel is defined as a pixel or sub-pixel that has failed and is permanently in the on position. This can be either with a single or multiple sub-pixels for a given pixel and is best observed on a dark or black background. A white pixel means all three sub-pixels have failed while a green, red or blue pixel means one of the sub-pixels has failed. <br /> Hope this helps, if so do rate the Tip

How to fix a dead or stuck pixel on an LCD screen


A dead or stuck pixel on an LCD screen or TFT can be incredibly annoying. You'll be staring at it for days on end, wondering for how long you'll be without your screen or maybe your entire laptop if you decided to turn it in for repair or replacement. All that grieve over something as unimportant, yet highly irritating as a malfunctioning pixel.<br /> Before you run the item back to the store though, you should try to see whether you can fix it yourself! This, if done carefully, will not hamper your warranty and might save you a lot of time and worries. So let's see what you can do yourself.<br /> Let me say that any new LCD or TFT monitor should be tested for pixel errors. This can be done simply by running it through a palette of basic colors and black and white in full screen mode. The software, which we'll get to in a second, can do that.<br /> First let me explain what you may be seeing. Is it just a stuck pixel or is it in fact dead? A stuck pixel will appear in any of the colors that its three subpixels (red, green and blue) can form, depending on their functionality and brightness. In a dead pixel all subpixels are permanently off, which will make the pixel appear black. This may result from a broken transistor, in rare cases however even a black pixel may just be stuck. So if you're seeing a colored or white pixel, your chances are pretty good and if it's black, there is still hope.<br /> Let's turn to the software now. If you're not on Windows, scroll down for some online tools!<br /> <b><a href="http://udpix.free.fr/">UDPixel</a> (Windows)</b> I recommend UDPixel to quickly identify and fix pixels using a single tool. The program requires .NET Framework 2.<br /> <p><img src="fixpixel02.png" /> With the dead pixel locator on the left you can easily detect any screen irregularity that may have escaped your vision until now. Should you have identified a suspicious pixel, switch to the undead pixel option, create sufficient amounts of flash windows (one per stuck pixel) and hit start. You can drag the tiny flashing windows to where you found the pixel in question. Let it run for a while and eventually change the flash interval.<br /> <b><a href="http://flexcode.org/lcd.html">LCD</a> (online)</b> This is one tool that lets you find and eventually fix stuck pixels. It packs many options into a singly tiny window, but once you have an overview it's straightforward and easy to use.<br /> <p><img src="fixpixel06.png" /> To test the screen click the small 'pick a color' box. The colors you should test are red, green and blue. Additionally you should test white and black. Follow the instructions in the box to gain the best results.<br /> <b><a href="http://tft.vanity.dk/">Online Monitor Test</a> (Online)</b> This is a very thorough test not only meant to identify bad pixels, but also powerful enough to test the quality of your monitor. You can choose between three different modes to test your monitor. This tool either requires flash (online version) or it can be installed in the executable mode.<br /> <p><img src="fixpixel03.png" /> What you will need to just test for stuck pixels is the HTML window. Toggle full screen by hitting F11. What you will see is displayed below.<br /> <p><img src="fixpixel04.png" /> 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 of the menu. Then click on the homogenity 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, you may find the following online tool helpful.<br /> <b><a href="http://www.jscreenfix.com/basic.php">JScreenFix</a> (Online)</b> Alternatively, and if you're not using Windows XP, you can use the online tool JScreenFix which launches a Java applet to fix stuck pixel.<br /> <p><img src="fixpixel05.png" /> The tool launches a small applet in a separate browser window and you can drag the window to the respective spot or run it in full screen.<br /> Hands On (Offline) Should none of these tools resolve your pixel issue, there is one last chance. You can combine any of the tools and the magic power of your own hands. There is a very good description of all available techniques on <a href="http://www.wikihow.com/Fix-a-Stuck-Pixel-on-an-LCD-Monitor">wikiHow</a>. Another great step by step guide can be found on <a href="http://www.instructables.com/id/Fix-a-stuck-pixel-on-an-LCD-monitor/">instructables</a>.<br /> But let's go through one technique real quick:<br /> <ol> <li>Turn off your monitor.</li> <li>Get yourself a damp cloth, so that you won't scratch the screen.</li> <li>Apply pressure to the area where the stuck pixel is. Try not to put pressure anywhere else, as this may trigger the creation of more stuck pixels.</li> <li>While applying pressure, turn on your computer and screen.</li> <li>Remove pressure and the stuck pixel should be gone.</li></ol> This works because in a stuck pixel liquid in a subpixel has not spread equally. In combination with the backlight of your screen, this liquid is used to allow different amounts of light to pass through, which creates the different colors.<br /> Should all of these approaches fail to fix your pixel warrior, at least you'll now know it's not simple to fix and the LCD may indeed need to be replaced. But please do let us know if these tips helped you to fix your pixels. In any case, good luck!

Hitachi ultra vision tv stuck on on moment please screen


Another malady common to plasma TVs are stuck pixels. This is where a red, green or blue pixel will fail to reset and remains conspicuously on the screen in the midst of the new images being displayed. There is a useful third-party program called JScreen Fix. This utility stimulates the pixels in the television through an intensive and prolonged burst of colored static. Many times this is enough to remove the stuck pixel. To utilize this program, you will need to run it off of a laptop that is hooked up to your plasma television. To download JScreen Fix, http://www.jscreenfix.com/

Blotted screen in my hp laptop


1.Locate the problem pixel. Display a true black image on your HP's monitor. You can do this by playing a DVD on your HP laptop, and pausing it on the black screen just before the movie starts. Once you bring up a black image on screen, the stuck or dead pixel should be visible.
2.Try applying direct pressure to the problematic pixel. After you've located it, turn off your laptop. Place a soft cloth or rag over the pixel to avoid damaging your screen. A soft chamois works well. Using the tip of a pen, apply gentle pressure to the pixel. You don't need to press hard, as too much pressure can crack or scratch your screen. While applying pressure, boot up your laptop. This should force the pixel to begin working properly.
3.Tap the pixel. With your Toshiba booted up and an image on the screen, gently tap the pixel with the rounded end of a pen cap. Tap hard just hard enough to see a small white flash on the screen. Tap your HP's screen until the pixel begins working properly.
4.Download a stuck pixel program. Several programs, including JScreenFix, UDPix and Pixel Protector, are available for download and can help fix a malfunctioning pixel. These programs display rapidly changing colors and images on your screen. The flashing colors and images can force the pixel to begin functioning properly.
5.Contact HP. If none of the above methods work, your screen may have a pixel that is truly dead. If that's the case, the only option is to replace the display completely. Contact HP customer support at www.hp.com to find an authorized repair service near you.

Is it true that when one pixel goes out, others are soon to follow?


No, that's not true at all. Each pixel is its only little device - one pixel does not effect another. The pixels work together to make a picture, but are all controlled separately. If your pixel is "stuck" and not dead, then you may be able to fix it! A stuck pixel is red, blue, green or white, while a dead pixel will show up as black. Sometimes a stuck pixel can be fixed by covering a pencil eraser with a cloth and pushing down on the pixel gently while the TV is on. So, in summary - no, one bad pixel doesn't mean any other pixels are bad. Hope that helps, Alex

Dead pixel


Please read the WHOLE of this guide before starting. Software Method
  1. Try running pixel fixing software. Stuck pixels can often be re-energized by rapidly turning them on and off. If this fails, complete the following steps.

Pressure Method
  1. Turn off your computer's monitor.
  2. Get yourself a damp washcloth, so that you don't scratch your screen.
  3. Take a household pen, pencil, screwdriver, or some other sort of instrument with a focused, but relatively dull, point. A very good tool would be a PDA stylus.
  4. Fold the washcloth to make sure you don't accidentally puncture it and scratch the screen.
  5. Apply pressure through the folded washcloth with the instrument to exactly where the stuck pixel is. Try not to put pressure anywhere else, as this may make more stuck pixels.
  6. While applying pressure, turn on your computer and screen.
  7. Remove pressure and the stuck pixel should be gone. This works as the liquid in the liquid crystal has not spread into each little pixel. This liquid is used with the backlight on your monitor, allowing different amounts of light through, which creates the different colors.

Tapping Method
  1. Turn on the computer and LCD screen.
  2. Display a black image, which will show the stuck pixel very clearly against the background. (It is very important that you are showing a black image and not just a blank signal, as you need the backlighting of the LCD to be illuminating the back of the panel).
  3. Find a pen with a rounded end. A Sharpie marker with the cap on should be fine for this.
  4. Use the rounded end of the pen to gently tap where the stuck pixel is - not too hard to start with, just enough to see a quick white glow under the point of contact. If you didn't see a white glow, then you didn't tap hard enough, so use just slightly more pressure this time.
  5. Start tapping gently. Increase the pressure on the taps gradually for 5-10 taps until the pixel rights itself.
  6. Display a white image (an empty text document is good for this) to verify that you haven't accidentally caused more damage than you fixed.

Tips
  • If the pressure and tapping don't work directly on the stuck pixel, start moving outward around the stuck pixel. If you see the pixel flicker while doing this then you know where you can focus the pressure and tapping techniques rather than directly on the pixel.
  • Many people report success with this technique but these instructions won't work in every case. It may take a few attempts to make sure you are pressing exactly on the stuck pixel.
  • These instructions will fix "stuck" pixels, not "dead" ones. Dead pixels appear black while stuck pixels can be one constant color like red, blue or green.
  • An alternative, but similar technique involves gently massaging the stuck pixel with a warm damp (not wet) soft cloth.
  • Alternative technique to tapping: Using a rounded pencil eraser, push with moderate pressure into screen at stuck pixel.
  • If these instructions don't work, you can hopefully get the monitor replaced through your manufacturer. If your monitor falls under the specifications of replacement, get in contact with the manufacturer to set up replacement plans.

Warnings
  • Do not attempt to open the monitor as it will void the warranty and the manufacturer will not replace it.
  • Make sure you don't get any electrical equipment wet or it may break.
  • Some people claim that touching the screen can cause more pixels to become stuck, although this has not been proven.
  • Be prepared to suffer a complete loss; you may crack the glass when tapping or putting pressure on an LCD assembly.
