Dell D600 lcd very dark

mcdevito75 here, Sounds like it"s burning out, you may have to replace the screen, Check with Staples, best buy or any computer outlet for their advise.

I have a similar problem currently. Boot and try pressing Fn+Up arrow repeatedly to raise brightness. Then flick the little button right above your volume control that tells the laptop youve closed it. If you see the screen flicker on/off then its the button. Otherwise reboot and try shining a light at the screen from different angles and see if you can see dark images. If you can see windows boot up but dark, then it is almost certainly your LCDs backlight. If you can't see dark images, next try using the VGA output plug at the back of your laptop to connect to a different monitor. Within less than 1 minute you should see the image on the external screen. If not, try pressing Fn+F8 a few times to toggle the output. If still no picture on the external screen your video card might be fried. If you do get a picture on the external with or without seeing dark images on the laptop, then it is a problem with either the LCD screen, it's inverter, or the screens flex cable. Check Dell support for your systems original parts list HERE. You will need your laptops Service Tag number, which is on a sticker on the bottom of your laptop.

Hope this helps, Good luck.

Connect an external monitor to your laptop and power it up, if you seethe normal Windows images then the video card and laptop is OK and theproblem is the backlight.

If you see a very dim image or flicking image on the LCD screen it means you have a backlight problem.

Dimimage and/or dark display on the laptop's LCD screen indicates a faultyLCD backlight and it could be the inverter that supplies high voltageto the CCFL lamp or it is the CCLF lamp is nearly burnt out or burntout, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Thank you Sir, Have a nice day.

Hi there if you have plugged into your external vga port all you have to do is press fn + f8 that should now show the image on both laptop and external ie projector

Hello,

The 14.1" inch screen is compatible with Latitude models D500, D505, D510, D600, D610 and Inspiron models 500m, 510m, 600m.

You may also need a screen inverter - in fact that is often the reason a screen is considered to be failing. The lcd inverter can be one of the most common items to become defective in a laptop computer. You may need a lcd inverter replacement if your screen is dim, dark, colored oddly, blinking, flickering or has dark stripes. Just something to keep in mind.
Hope this helps,

Chris

Looks like the backlighting on the display has failed, sometimes it is just a lose cable, buy most often the LCD needs to be replaced.

to check the cable see the manual at http://support.dell.com/support/edocs/systems/ins9400/ for how to get to the LCD cables (usually just under the cover that the power button is on)

It sounds like a LCD backlight problem. Bring it to an authorized repair shop.

REMOVE ALL POWER FROM THE COMPUTER BEFORE YOU ATTEMPT Try this first remove the control plastic panel above the key board,reseat the lcd cable to the motherboard.If no go you may have a loose or bad inverter.Here is how to fix this,REMOVE THE BATTERY,AC CORD.On the front of the display you will see some little rubber covers these cover the screws revove the make sure you put them out of the way,remove the screws remove the bazel.Below the LCD is a little card about six inches called a inverter make sure its snug(CHECK THE WIRE PLUGED INTO IT FROM THE LCD),since you got this apart you might want to look at the rear of the lcd the back panel comes off too but you will have to remove screws as well.THAT CABLE SHOULD BE SNUG AS WELL YOU CAN USE A PIECE OF TAPE TO KEEP IT SECURE.Now thats it for the physical display.Put everything back together and try again.
Good luck
