Hello
These white lines (horizontal or vertical) may be an issue with the DMD board. One way we can narrow the problem down is with a simple test: bring up the TV menu on the screen. If thewhite lines are still visible through the menu, then it's even more probable than the DMD is defective; if not then the digital video can also be held accountable.If you decide to go for a new DMD you'll have to search by part number, NOT by model number, the main reason is that two TVs with the same model number may have non compatible components because they are different generation when they assembled.
Also if by any chance you can't find the DMD sold separately, your next option is to buy the entire light engine that includes the DMD, and obviously that's going to be more expensive. If you are trying to save money and you really know what your buying try eBay, you can get a really good deal over there, how ever if you are not familiar with TV parts, and don't want to take a chance buying something that might not work, try online stores that specialize in TV parts or contact authorized LG Service Center .
Hope this helps.

The display of my phone is working but for last 2 days , there are 3 -4 horizontal lines . i dnt knw the reason . i evn tried factory settings but of no use . please provide me with necessary remedy for...

Hi, possible causes for horizontal line on screen are,

Phone Screen problem and,
The flex of a phone.

When a screen displays horizontal lines on the screen, is when screen of the phone is getting damaged due to phone falling on the ground,or hitting phone on an object can cause horizontal line on a screen.
Solution to this problem is to replace the screen of the phone.



The flex of the phone can also cause horizontal lines on a screen. The flex is a thread like object inside the phone that makes the phone to function properly in terms of the display..

When the flex is getting damaged, it can cause such horizontal line on the screen display.

Solution for this problem,is to replace the flex.
Note : flex can be found only on slide phones.

Thanks for using fixya........

Lg phone screen cracked but when you look it closely it doesn't have crack lines. crack lines only appears when it is turned on and not present when the phone is turned off why am i suppose to do?

The glass of the lcd screen is not cracked, but internally the display is'nt working perfect, few lines are not displayed on the screen which makes us to assume that the screen is cracked which is not the case, you need to replace the display, it its one or two lines you can use the same display screen, their won't be any damage to your phone due to non display of few lines.

My laptop screen has a thin blue line going down, why has this happened?

You have the beginning of a failing Display panel, and will eventually need to replace the display.. you can hold the top left and right sides of the display screen-slightly bend forward and back, you should see the blue line either go away or it will produce more lines...

This is due to a short on the circuit board panel on the backside of the display panel that controls the Pixels on the Screen.. The Pixels are controlled In a Line Grid Fashion...

Lines on my display screen too.

More than likely you will need to replace the LCD screen. When it got wet, it probably damaged the LCD screen. Usually it justs blows them completely out.

A new LCD screen runs about 15 dollars shipped from ebay2.gif.

The W580i LCD is extremely easy to replace. Probably one of the easiest I have ever done.

Check out the following link for instructions on replacing the 580i LCD display and links to buy the screen.

Lines on phone

More than likely you will need to replace the display screen. Those lines are a symptom of the LCD screen going bad. If you are still under warranty, see if you can get it replaced

If not, a new LCD screen runs about 15 dollars shipped from eBay and is pretty easy to replace.

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.

Blue Vertical Line

It is sounding like when the laptop is turned on and heats up a bit, the line appears? Sounds like one of the panels is going bad or atleast has developed a problem. below are some tricks you can try to lessen the annoyance of the line. Dual-Scan STN displays are composed of 2 panels behind a single protective panel or screen. Because you are looking through the protective screen the display appears to be one large panel even though it is not. There is a physical separation line (gap) at the point where the two panels meet. When the computer is on and being viewed it is not unusual to see the visible separation line with the Dual-Scan STN displays. The line, actually the fine gap between the display panels, appears because the color and light pixels cannot run along the very outside edges of the panels. This line (gap) between the panels can be seen as a fine gray line and is most noticeable when viewing on a screen with a white or light background. Note the line may not be as noticeable when the screen is displaying certain colors or darker backgrounds. SUGGESTIONS: It is not possible to completely eliminate the line but there are some things you can try to reduce it's visibility. 1) Lower the display brightness/contrast. The brighter the backlight the more noticeable the line. 2) Use Wallpapers and Screen savers that use darker colors. 3) In the Control Panel/Display applet under appearance try different combinations of color schemes for your Window and Background choice Let me know what happens. Good Luck, Tim
