My screen has gone dull and lines have apeared in the screen iv tried display and then gone onto stability but no change the problem persists even when i turn it on and off to try and reset is there any help u can give

Most likely the main board...try locating one on Ebay, then go to you tube for a "how to replace" video.

While booting the PC changes resolution several times. It could be that by the monitor finally locks onto the signal, the PC changes it again so it tries to lock on again. Question is, does the video stay on when the PC finally stabilizes onto the desktop screen?

your display get gradually damaged.

Walter,

If this horizontal line appears no matter what you are doing, simply on the desktop or in an application, or even while you are booting up your laptop, then you have a monitor problem.

First try to right-click on the desktop in a clear space, find the option for changing the display options, and see whether a different speed (Hz) will change this and eliminate the line. If you're using, say 70 Hz, go to something else, like 60 Hz.

However, if this truly is happening even during boot up, you then have to try to get into the BIOS setup, which usually is shown right after turning on the system, for example, Setup: F2, or F10, etc. Try going in there and looking for the same thing - the speed of the monitor's refresh rate and changing it there.

Then restart and see whether the line is gone or not.

But if it persists, and your laptop is still in warranty, contact the Samsung Support people, and see about getting a replacement, or having them repair it. Hopefully, it is still in warranty, because a new screen for a laptop is an expensive proposition.

Good luck.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

It is either the firmware gone berserk or the screen. To find out which one, reinstall the firmware and power on. If the problem still persists, then it is the display IC inside that needs replacement. A trip to the LG Service Center is called for in any case.

grab your screen in the middle at the top,and flex it lightly,,kind of a twist ,does the screen change or the lines apear and move around,if it does check display ribbon at hinge for damage,and connection to graphics card,run dual display in clone mode with external monitor or tv,are the lines on it too?if they are .try reinstalling your graphics driver,and software,

may be the display is gone... just take to expert technician to have a check wit display... or may be last time when u gave for repair the display has not been fitted correctly by that techi ....just have a check wit other expert techi..........
