Green pixels appear at top area of screen after about one hour of use. Repair man said I needed a new display monitor for 3500. I noticed the two small fans located near the top of TV inside the panel not spinning. I placed an external fan to cool the rear of panel and the green pixels went away. Should I replace the small internal fans and see if that will fix the problem?

Hi, In my experience, it looks that the screen pixels are damaged in some areas. It could be due to mishandling, may be fallen or it could be a manufacturing defect. If the device is new, ask for the replacement as it may enlarge due to heat. Rest is your luck :)

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.

First right-click on the desktop and then left click on Properties from the menu that appears.

The display properties dialogue box will appear as shown in fig. below, click on the settings tab at the top right of the box.



The areas worth noting are: google_protectAndRun("ads_core.google_render_ad", google_handleError, google_render_ad); Screen Resolution
This slide bar is what you use to change the resolution, the options you have will depend on your graphics card and monitor, but the standard options are 800x600, 1024x768 and 1152x864.

Normally the default (in XP) is set to 800x600 which means the display will be 800 pixels wide and 600 pixels high.

Color Quality
This pull down box will contain the current colour options available, again this will depend on your grahics card and monitor, for best results select the highest option available.
Changing the ResolutionTo change your resolution simply slide the bar along to the resolution of your choice and then click the Apply button.

After clicking Apply your screen will resize to the new resolution and you will be presented with a confirm dialogue box, if you are happy with the way your screen looks then simply click Yes, if you would like to try a different resolution click No.

When you have finished simply close the Display properties box.

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.

try to adjust your computer's display setting, sometimes improper display settings causes that.
Another area to look is to see if you have any "Hot Keys" setup for that corner. Sometimes those corners are setup as shortcut key for doing something. You might have it set without actually knowing.

Hi Casey,

If the problem is getting worse, than either the pixels are dying (so to speak) or you might have a problem with the monitor's screen.

Unfortunately, if either of the above are true, then the only way to fix it would be to replace the screen, which can be quite expensive. If you agree that this is the problem then you'd be better off getting a new monitor instead of spending money to get it repaired.

Good Luck.

You are about reade to have a scan ic failure.Try to get it to a repair center asap.Have them replace the top 2 scan ic's

You need to adjust the panel voltages, adjust the VS voltage to around 186 volts, if that doesn't change it then adjust the V-Scan voltage down, turn the unit on and apply a video source to it, and while adjusting the voltages look at the screen and you should be abe to watch the video noise fade out.

Hello! Sorry to hear of the Tennis Ball Masacre. I believe your problem to be twofold in nature. First the glass in side of the LCD screen is very fragile and the tennis ball most likely ruptured it. the streaks are most likle the liquid crystal solution leaking out. the dark streaks represent the absence of the fluid. Secondly, the monitor shut down appears to be from the back light / inverter circuitry. Sounds like it may be time for a new display. $40 to $60 for the inverter board and $80 or more for a new display screen, you may as well go the couple of extra dollars and get a new monitor. Hope this puts it in perspective for you. Sorry it is so bleak!

of course it is. A defective product is a defective product. The specs say 240 X 320 which is 76800 pixels but they onle sent you 76799 that work!! lol
