Lcd/monitor problem on dell 6400

When I try to set the background light on bright, my lcd light just turns off competley. It looks as though my computer was turned off, but the computer is still running as a matter or a fact if you hold a flaslight on the side of the screen you can see. If any body can hel please let me know what to do. I don´t know if it is a bad inverter, or a bad screen light but it is really anoying because I can´t use my computer unless I keep the lcd light at the lowest.

On my Dell E193fpc monitor, the background lighting goes off after a few seconds. The actual Screen-image is still there (can be seen in bright sunlight). How can I get the backlighting to work proper


This sounds as though there might be a problem with the inverter (this is a component that supplies a high voltage for a tube(s) that illuminate the screen.

As there are high voltages on inverters, this is really a job for a repair shop.

Background too white


I looked this up in my Dell 1908FBPL instructions which should be similar. On the lower right edge, you should have Brightness & Contrast and Auto Adjust controls. These controls interact so you may have to fiddle back and forth to get it right. First, note whether brightness becreases when you press and hold the down (-) button. Check to see whether Auto Adjust changes anything. Also try turning the monitor off then back on.

My dell inspiron 6400 won't start, red light then green light flashes ansd nothing happens, try to take out the battery and putting it back, no results, help


The following troubleshooting guidelines are basic troubleshooting steps. Battery Charging It is recommended to charge the battery while the system is off for faster charge times. Users may notice longer charge times when the system is powered on and running graphics extensive applications.
No POST If the system does not perform a Power On Self Test, there are various things to look for:
  1. Check to ensure that the system has a power light.
  2. If the system has no power light, ensure that it is plugged into AC power. Remove the battery.
  3. If the system has power but is not performing a POST, check to see if the keyboard status lights flash to indicate a successful POST, but no video, or that the keyboard status lights are lit in a sequence indicating a system problem.

  1. With the power off and the system unplugged, remove all CRUs from the system and reconnect that AC adapter to the system and try again.
  2. Run the On Board Diagnostics (OBD).
Video If the LCD on the system shows no display, or has other LCD problems, there are some basic steps to take:
  1. If the LCD is not displaying video or the video is garbled, run the BIST Test.
  2. If the LCD is not displaying any video, connect an external monitor to eliminate a no POST problem. A good image on the external monitor eliminates a video card problem or a POST problem.
  3. Connect an external monitor when possible for all LCD related problems, to help eliminate a software possibility or video card problem.
  4. If the LCD has extremely dim video, attempt to adjust the brightness or connect an AC adapter to eliminate a power management conservation setting set in the BIOS.
  5. If the LCD has lines on the screen, check the system during POST as well as system setup to verify if the lines are present in all modes of operation. Run the BIST Utility.
  6. If the LCD has color problems, run the BIST Utility.
  7. Run the On Board Diagnostics (OBD).

Monitor Problem


lower right hand side are some monitor setting buttons.

They should let you configure your brightness and contrast,also sharpness.

One button may do an auto fix.

Also in your win control panel click on display, advanced. and set your resolution until your happy with the picture.

After a few seconds after boot up, the monitor turns black, images are visible in the background, but very dark. as if it is in a power saver mode.


Do you have brightness adjusting software. if so change the settings. if not there is something internally wrong with your back light.

DELL inspiron 6400 laptop screen turned black


this sounds like a classic case of inverter problems, it could be just inverter coil thats gone which is an inexpensive repair, if it is the inverter then its a bit more.
try the Fn the F key that shows two tv screen icons, it may just have switched to external mode by accident

good luck
