Dead pixel repair


Hi Tasha,
Unfortunately, repairs at the "pixel level" are not possible. The display is an "all or nothing" type of repair (I'm not talking about the back lights and support electronics - I'm *only* talking about the display screen). That means that the entire screen is replaced if there are to many dead pixels. (Most screens have dead pixels - manufacturers limit the number of dead pixels on a screen that can be assembled to a TV). If it the Quality Assurance people in the factory find a number of dead pixels that is less than a certain amount - it is "good" and ships. If it is more - it is scrapped.

Generally, your options are: live with it, replace the screen or buy a new TV.

Acer monitor has green lines on the scren


Liquid Crystal Display (LCD) screens use less energy and display a clearer picture than the Cathode Ray Tube (CRT) displays that preceded them. These new LCD screens now dominate the computer monitor market. From time to time, however, pixels can become stuck and a green line can display on the screen. Removing this line is sometimes possible without sending the screen to the manufacturer for expensive repair.

Locate the pixels that are stuck on the screen. Download a free screen repair software program, such as UD Pixel or JScreenFix. Run the software and allow it to find and attempt to repair the stuck pixels. Turn off the LCD monitor. Apply the damp cloth directly over the stuck pixels and use a gentle pressure to spread the liquid within the screen.

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.

White dots appearing on screen, also have black dots if you look closely...


It can be pixel problem. Every pixel has one transistor to switch off or on. I hate how manufacturers treat us because lot of them 'believe' that this is not a problem (must be more than 6-8 pixel problem on screen for changing). Sometimes little press with finger and shutting down screen can help, but it is possible to do worse if it is to hard press. Price for screens depend on that tolerating of bad pixels from manufacturing. Only few manufacturer can give you guarantee pixel free screen. It is good to know that we have right to return device after buying if we are not satisfy.

I install window 7 but my benq 15" lcd monitar's screen rosuation not competible. pls guide me how i increase the rosulation thnx


As for your 15" LCD BENQ Monitor, "1024 x 768" pixels is the Maximum Resolution
If you increase your screen higher than the Maximum resolution you get a black screen! because the monitor cannot support the resolution higher than "1024x768" pixels.

How to change your screen resolution Win 7-> Link

FYI
Here are typical resolutions for some popular screen sizes
19-inch screen (standard ratio): 1280 x 1024 pixels
20-inch screen (standard ratio): 1600 x 1200 pixels
22-inch screen (widescreen): 1680 x 1050 pixels
24-inch screen (widescreen): 1900 x 1200 pixels

Hope it helps.

What does it mean by dead cells?


I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

Dead pixel


Dead pixels cannot be fixed, each pixel is controlled by a transistor that is part of the LCD screen. If it is bad, the only option is to replace the LCD screen.
