Not much you can do about that, sorry. You could try to replace the screen but I would not suggest this without lots of electronic knowledge.

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.

Lines all over screne vertical shuttering


Hi,

Looks like your LCD screen got some dead pixels.

My suggestion would be to bring that laptop to your nearest service center or technician and have them check the monitor.

Am afraid to tell you that most dead pixels are unrepairable, hope that only the connection on the LCD screen are at fault.

Happy to sove your problem!

Thakns for asking Fixya!

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 pixels on my screen and transfered to pictures when developed I have a panasonic dmc-tz3


Hi!
Do you mean that these pixels go to pictures too? Then they are dead pixels on the imager (CCD) not the display. The CCD has to be changed - you have to contact Panasonic service center to find out the price (could get expensive).

Can I see the difference


Visually, there is very little difference to the eye of the average consumer between 720p and 1080. However, 720p can deliver a slightly smoother-looking image, due to the fact that lines and pixels are displayed in a consecutive pattern, rather than in an alternate pattern.your tv is display format is 720p and blu ray is 1080p. what happen is it will be scaled into 720p. old tv set format is 480p 720p represents 1,280 pixels displayed across the screen horizontally and 720 pixels down the screen vertically. This arrangement yields 720 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another. 1080p, on the other hand, represents 1,080 horizontal lines displayed sequentially. This means all lines are displayed during the same pass. 1080p is the highest quality HD display format. 480p represents 720 pixels displayed across the screen horizontally and 480 pixels down the screen vertically. This arrangement yields 480 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another.

Black lines appeared on the screen


im sorry but it seems thats the screen had a dead pixel from when you bought it, the dead pixel has then since killed off the surounding pixels and they in turn have done the same. this sometimes forms a line but in some more unfortunate cases the screen can lose visual on both x and y axis's.
unfortuantly your manufaturers warrenty will not cover dead pixels as they are so common and there is a torrerance for them without doing harm, but some times dead pixels can spread.

hope this helps.

Red pixels on the Srceen


Dead or stuck pixels are not uncommon in LCD displays, and the less you pay, the more likely it is to happen (as a general rule) Most manufacturers will a dead pixel warranty, ranging from 7 days to lifetime.

Read your warranty carefully, and speak to the place where you bought your display.

I hope that helps, if you have any further problems, please add them ass comments to this question. If I have been able to answer your question (or not) please click on one of the ratings buttons to let everyone know how I did.
