This is most likely cased by your LCD screen being defective.

The inverter will either light the back light or not, it does not have the ability not to filter certain parts of the screen. It could however be that if your seeing wash out and it goes from super bright white to a dimmer bright white the inverter has failed and the bulb is running at full power.

Most likely it is your LCD.

To test your inverter, turn your computer off.

Press and HOLD the FN key while pressing the POWER key.

Once you see booting dell diagnostics, or something similar you can release the FN key. You might have to release the POWER key sooner if the under shuts down.

Screen is very dark, external screen displays desktop. what could have cause this problem? XPS Laptop M140 with integrated Video Card, replacing mb is not an option. Could it be bad video cable or...
The inverter handles how bright the display is because it takes the DC power from the adapter and converts it to high voltage AC power for the backlight. When the inverter starts to and finally fails, the screen goes dark. Your problem is most likely an inverter failure.

When my xps m140 laptop boot up after few minite lcd screen blak out. how to fic this?
There could either be a problem on your LCD screen, or Graphics card, to determine it. Try plugging an external monitor on your laptop and see if the display turns black also on the other monitor. If no, the problem is the LCD, but if yes (still black screen on the external monitor) it means the problem is on the graphics card.

The dell logo flashes then the screen goes blank. The hard drive keep flashing like the laptop is booting up okay it is a xps m140 and has vista home as a o/s
After the logo flashes, press F8, repeatedly, until a white-over-black "boot menu" is displayed. Choose "Safe Mode", to see if this "minimal" version of Windows will startup successfully.

Dead screen on an xps m140. How can I figure out
You said the computer boots up. How do you know for sure that the computer really boots up. I say this because from my experience this are the symptons of a bad RAM in a notebook computer. If you are good at troubleshooting, get a RAM of similar specification and change it to see. If the specs of the RAM you get (get one from a friend's computer), are similar the notebook will most likely display.

Dell xps m140 screen goes blank
More like the back light has burned out on the LCD. Not an expensive fix, but time consuming. Almost easier to put in a new LCD (about $60us on Ebay), and is something you can do yourself.
