Pixel damage My 4 yr. old daughter threw a wii remote at the tv and now there are "stuck" pixels of blue, red and green. You can see the point of impact and it almost looks as though the glass has shattered, but it hasn't. It's just these "stuck" pixels. Anything I can do? thanks. Joanna Chrystal

I am having problems with my tv as well. I took it off the tv stand mount and had it leaning on my knee and now there is a huge spider crack in the picture. The screen seems to be fine and there is still sound. How do I go about fixing this?

Download pixel fixer if its a computer

For a tv, take it to a tv repairman and he has a version of pixel fixer that works for flatscreens

Dont do it yourself if its not a windows or mac, those are the only platforms that are user friendly enough to attempt a "handyman" pixel fix

Keep in mind most pixels cant be fixed so the repair guy will probably just turn those off, dont worry though you cant see a "black dot" where the pixel is turned off, its too small for that

Running a video that quickly forces pixels to change colors MIGHT fix you blue and red pixels as those are stuck on one color but the white pixel is what's called a dead pixel. Any white or Black pixels are dead and there's nothing you can do about it.

any red, green or blue pixels are simply jammed and you MIGHT be able to fix those ... maybe.

Those small pixels are now damaged not much u can do with it. Some people say you can press on the screen the pixels affected and possiblilty get them to make contact and light back up ( I honestly highly doubt it) If u can live with and not very distracting keep watching it. But if you want to order a replacement, more than likely it will cost more than the TV did when u bought it. If its still under warranty get it replaced if possible.

SOURCE: Broken screen

if it is limited to external glass the glass can be ordered separately but if there is internal crack on pdp itself would have to replace pdp. from my experience generally if it limited to crack on external glass there still should be picture so there may be additional damage to plasma display itself

Ghost image and snowy colorful pixelation with vertical black bars? You can try a hard reset by unplugging the unit completely for 4 hours. However you may have a prob with the YSUS and the YBU-L (YBuffer Upper-Lower.) Perhaps even the Logic Main may be defective. If you are still under warranty take it to a service center ASAP. If not Get out your Voltometer. You can email me for some help...

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/

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

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

Blue vertical line


The lines appearing on your LCD means it has a defect on the screen.

There are 3 types of pixel defect
1) dead pixel - pixel is always off
2) stuck pixel - pixel is always on
3) hot pixel - pixel is on but in red, green, blue or yellow, can also be a light black color

You can try to fix stuck or hot pixels but dead is dead.
1st method, flashing different colors rapidly:
JSScreenfix.com has a great tool. This is their free java applet or you can download it below.

2nd method, applying pressure to pixel:
Damp paper towel, Small stylus or dull pencil.

3rd method, tapping the pixel:
Pen with cover on or another small, blunt object.


If your laptop is still under warranty, get it replaced. If not you are looking at the most expensive part in a laptop to get replaced. (LCD screens on laptop is roughly equivalent to 40-60% of the total laptop cost

Lcd tv with wrong color on one pixel


LCD screens occasionally have what are called "Stuck pixels". There is a tutorial in wikihow which might help you out here:

Try that and see if it helps. Stuck pixels are actually a slighty common problem.

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.
