My H233H monitor has one bad pixel... it bright green! I tried a software pixel massager with no avail! I massaged the screen while turning the monitor on and off.... still green little bugger looking at me! What do I do before I have to return the monitor??

Try this free web application.
it fix type of stuck pixel, massage the pixel can help reset it.

good luck

Those green dots are dead or "tired" pixels. The only thing you can try to fix this, is doing a pixel massage. Grab a pen and put some sort of towel over it and make a circling move over the pixel.

If it won't work the only thing you can do is get used to it that you have a dead pixel. ( i also have one. Very annoing)

1. Start by turning off your monitor.
2. Find a pen that has a rounded, dull end and get a slightly damp cloth to protect your screen.
3. Fold your cloth in two so that you do not puncture it accidentally. You don’t want to scratch your screen, do you?
4. Put the cloth in front of the stuck pixel and start applying slight pressure on it with your pen. Do not put pressure anywhere else than on the defective pixel, or you may break additional ones.
5. Continue applying pressure, and turn your monitor on.
6. Remove the pen from the screen, and voilà! The stuck pixel should be gone.
7. Be very careful doing this. The monitor is very fragile and too much pressure may cause more dead pixels. You can also just try it with your finger while the screen is on... just massage the area. NOT TOO MUCH PRESSURE! also try tapping that spot... if you see a little white color while you tap that is plenty of pressure. Let me know if that helps it. (This is only for LCD)

Hi, Sorry to hear you are having problems,
Sounds to me like normal use, how old is this iMac?
Has there ever been any pressure put on the screen on that spot?
You can try massaging it away, gently but firmly, massage in a circular motion in a larger and larger circular pattern, sometimes that helps.

Hey man, thanks for coming to me. Um yea, massaging may help but too hard will do damage since it is LCD is Liquid Crystal Display and it is fragile and easy to damage. The water should clear up in a few months, if not i would look at replacing it which can be costly. Here is a link to fix your unstuck pixels

Now im not liking that bit about how you mentioned was spreading so leave it for about two days, give the therapy for the screen a try and let me know if the laptop screen is healing. For the moment if you have one i recommend you hook up a VGA Monitor, old school stuff if you can and give the LCD a rest. I will post as a solution but comment back and i will keep helping you as much as you need it.

This is probably a dead pixel area and there may not be anything that can be done other than replacing the screen. This could also be a stale area in the liquid crystal. Try massaging the area firmly, just hard enough to make the screen change color, but not too hard as to make it turn black. If it's a stale area this should refresh it. If it's a dead area, then I'm afraid replacement is the only option.

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.

hi if your pixel is permanently brigthing you can try to press gently on the screen on the bright dot to expanse the liquid, sometimes the pixel freeze on lcd monitor.
hope this helps

Sylvia,

It's seems you had a stuck pixal... Turn your monitor off and try this tips: Wn't work in every case. It may take a few attempts to make sure you are pressing exactly on the dead pixel.These instructions will fix "stuck" pixels, not "dead" ones, like red, blue or green.

Good lucks!

Hey, Picas!
So you have a pixel problem, huh? OK, you said a "bunch" of white points. How big is this bunch? Are they all in 1 area or are they scattered around?
There are a couple of things that you can do that may help. First, you can try to massage them away. You find a cloth that is soft enough that it won't scratch the face of the LCD. Then you wrap this around you finger, press somewhat firmly and "massage" the area where the problem pixels are located. Some people use a quarter rather than their finger.
The second thing that you could try is to run a screen exerciser that I found online. But, I don't remember where I got it. If you send me your e-mail address, I'd be happy to sent it to you. It's a small exe file that lets you do a number of things to your screen, and supposedly will help by repairing pixels. I've not had a chance to try fixing pixels with it yet, but have used it for other purposes.
