Try and determine what is wrong with your LCD screen first and you can then decide the best course of action. Follow these instructions to determine the fault and then check out LCD Parts WEB site for parts, replacement LCDs, service and DIY info..

You may have a faulty inverter or loose power inverter connection. OR
You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Try booting in Safe mode, see if you get video

If you do, reboot in VGA mode, then adjust the refresh rate accordingly

A replacement LCD is about $200 on EBay

Charging light is flashing


There are two possible causes for this issue:
1) Your dell 9400 charger is malfunction
2) Your laptop dc power jack is loose or dead

Possible troubleshooting step:
1) Borrow a compatible dell charger to plug in your laptop, if it works without any issue, it means your dell inspiron 9400 adapter need to be replaced.

2) If the compatible dell 9400 charger won't work normally, the problem may lie in your dc power jack.

Hope this will help.

My inspiron intel laptop screen has been darkening and flickering and I tryed to do what my laptop told me but it doesn't work is there another solution?


What did your laptop tell you?
Just curious

1) "Help, I'm being held prisoner inside this laptop"
2) "I'm tired, and I'm going to bed. Lights off"
3) "Use the Brightness control, and brighten this screen up"

J/K

An LCD screen does not produce light. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

An Inverter (Screen Inverter) is used to convert the power from the laptop, to the Backlight, and LCD screen.

90 PERCENT OF THE TIME the fault is the Inverter, when it's a Display Assembly issue.
The rest is a bad LCD screen.

The Inverter is a small rectangular circuit board.
Example,

http://www.nylaptopparts.com/index.php?main_page=product_info&cPath=91_95_125&products_id=299

It is mounted behind the Display Bezel, and at the bottom of the LCD screen.
{The Display Bezel is the thin plastic frame in front of the LCD screen. Resembles a picture frame)

http://support.dell.com/support/edocs/systems/ins9400/en/sm/display.htm#wp1006390

Scroll the page down.
(The Inspiron 9400 and Inspiron E1705 uses the same service manual)

Suggest you connect a VGA monitor to the back of the laptop, to the blue VGA connector.
(Laptop OFF, external monitor {VGA} OFF)

You can use a VGA monitor that is a CRT. Looks like a small TV.
Or you can use a flat LCD screen monitor if it has a VGA cable.

Turn the monitor on. If it is a CRT model, let it warm up.
Turn the laptop on.

The display should automatically be on the external monitor. If it isn't press, and hold down on the Fn key, then tap the F8 key once.
No? Tap the F8 key again. (Still holding down on the Fn key)

If the graphics (Display) is the same on the external VGA monitor, as they it is on the laptop's internal monitor, you have a graphics chipset problem.
Usually requires motherboard replacement, unless you know a really skilled tech.

If the graphics are fine on the external monitor, you have problems in the Display Assembly.

More than likely the screen Inverter.

Pictorial guide for replacing the LCD screen, and the Inverter,

http://www.insidemylaptop.com/remove-lcd-screen-inverter-in-dell-inspiron-9400/

Suggest:
1) Use an ESD wrist strap, and connect it's alligator clip to a good ground source.
(I connect to an unpainted surface, of the metal frame of an empty desktop computer case.
You can also connect to a unpainted surface of a metal table leg )

2) Use a multi-compartment container for the various screws you will remove.
Label each compartment for the area the screw/s come out of.

If no multi-compartment container is available, you can use a clean egg carton as a substitute.
Label each egg holder.
Some screws look VERY similar to other screws.
DO NOT mix them up.

White screen


The white screen you are getting is it just right after turning on the computer? If yes it means that you were not able to see the Dell logo correct?

Try connecting an external monitor thru VGA. While monitor and laptop is on with white screen please do this. Hold down Fn key then press F8 at the same time. This will toggle the display from the laptop to external monitor. If laptop displays to external monitor means that laptop LCD needs to be replaced.

If you do not have an external monitor try this.
While laptop is OFF. Do this. Hold down the D key then press power button at the same time.
Check if the laptop will display colors the whole screen. If you still see white screen then LCD needs replacement.

LCD mean LCD panel or the whole screen together with LCD cable and Inverter.

Hope this helps.

Dell Inspiron 9400 laptop display problem


First power the system on using Fn+Power and see if the diags run and you have video. If you have video in the diagnostics, then I'd suspect the video card as the failure point.
Also connect an external monitor and press Fn + F8 to activate the VGA port If you get video on an external monitor, I'd suspect the LCD as the failure point.
