Dell Inspiron 6400. New screen fitted but too dark, cannot brighten it, have used the birghtness keys, any other suggestions

ldriscoll3:
The brightness of the screen does not generally depend on the health of the battery.

On the keyboard of your laptop is a "Fn" key. You need to press and hold the key down while you also press the "Up Arrow" key repeatedly. Each time you press the "Up Arrow" key while holding the "Fn" key down, the display will get progressively brighter until you reach maximum brightness. If you go too far and it gets too bright (not likely), just press the "Down Arrow" key while holding the "FN" key down until it's the perfect brightness

This is explained on page 33 of the user manual that you can download from here:

Hi there! Try this trick...

You can adjust the screen brightness within BIOS set up...

It works with Dell!!!

^_^

Hi, there is a key in your laptop which is called FN key. Press FN+ UP/Down Arrow for adjusting brightness.
Thanks & waiting for your feedback.

Please check for the display drivers or use the Fn and the up arrow keys to increase the Brightness.

Your backlight bulb went out, it's a long tube on the bottom typically, It's most likely taped to the LCD frame and encassed in a metal shield. Not for the faint of heart taking on the repair. Light fixtures are found on eBay however, or new LCDs of course

The Back-light on your LCD screen is bad, your crystals aren't illuminating, so it is dark.... very dark.

You need a new LCD screen.

Sorry.

there is a invertor in LCD. it makes your lcd bright white shine. if it doesnt work you can have dark view. i mean something going on the lcd but you cant see clearly. take to tecnic service your computer.

i hope it works.

Hi there.
Yes, if you can see a very faint image on the screen that indicates that the inverter or inverter coil has become defective and needs looking at or replacing.

Good luck and thanks for using Fixya!!

on the arrow keys are there any other symbols / colours

try screen fit in video options menu strech or a fn key and sumting else u might have hit on the kb itself thx nick
