I have two of these screens. One failed by showing a blank screen only and no graphic display. The second is now showing a shimmering screen which makes reading the display, particularly characters, difficult.
Is this a problem of a graphics card or, as I strongly expect, a screen problem. Is there a repair available or should I ditch them?

Hi,to me it would seem real strange that TWO monitors would fault simultaniously. I would be more inclined to believe that it is the Video card itself... The ONLY way to find out is try a replacement and see... try the monitor(s) on another PC see if they work.... if they do then it's ya card 4 sure.. if it's still the same well then it IS ya Monitors good luck.

This is an extended display. You can move open windows, icons, or folders over to the second screen. This is called a dual-monitor setup. You can also set the second monitor to duplicate what your primary monitor is showing.
There are couple things that will cause this, a bad inverter board (most likely) or the back light behind the screen has failed. But just to be sure hook a spare monitor to the video output on the back of the laptop, if okay! it is one of the above mentioned. If both display show the same problem it is the video graphics card on the motherboard.
First place to look will be the power supply section, look for bad caps (bulging tops or bottom seals), the post back what you see so we can guide you further for direction such as voltage checking, see example of failed monitors due to bead caps: http://s807.photobucket.com/home/budm/allalbums
First make SURE your monitor/screen is working (you can do it by plugging it into a working computer) Try putting a different graphics card in it, if it still gives a blank screen after leaving your computer on for a few min, then the problem is most likely *********** board, and it cannot be fixed.
First of all, check that the laptop is set to output video to the LCD. There should be a function key which will determine whether it is outputting video to the built-in LCD, the external monitor, or both. That should be holding down your "FN" key and hitting "F8." If it is on CRT ONLY, it should switch within 1-2 keypresses.
Secondly, take a good bright flashlight and shine it directly at the LCD panel from about 1-2 inches away. If you can actually see the graphics on the screen faintly in the background, your backlight is not turning on. The backlight is literally a bulb which lights up the screen, and they can burn out. It is repairable, and shouldn't cost more than $150.00 from a reputable repair shop.
It appears that the display resolution set in your display properties is out of the range that the LCD can display.
Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)
There may wrong setting of refresh rate. Most monitors work at 60 to 70 Hz refresh rate. Above that they tunned blank screen or out 0f range message displayed. Also check the output video signal. Please confirm technical specifications from the documentatation of the monitor.
