This model laptop uses a CCFL lamp for the backlight, it does not use LEDs for backlighting.
The CCFL lamp is attached to an inverter which supplies high voltage to this lamp.
For details on how to install and or replace CCFL lamps go to
www.lcdparts.net for information and parts.

I assume you are not replacing the whole LCD screen.

The sreen of my DELL XPS M1330 suddenly does not lght up!


It can be either the display is dead or it is a loose connection. If you are still covered by warranty then I would suggest you to contact the dell technical support. They will replace the part for you.
However if you don't have a warranty then you can buy this part from dell online store (the display) and you can fix it on your own - http://ahwee.com/how-to-disassemble-laptop-dell-xps-m1330 follow the instructions here to dismantle your laptop and refix it with the new parts. If you find any troubles doing so; please let me know; I will help you further.

Dell XPS M1330 - Backlight not working


If you are having issues with a backlight I would check the lcd inverter first. It is usually 20 dollars on ebay. I would avoid contacting dell as they are no help to people that are out of warranty.

Dim Screen when Power is Unpluged


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

Connect an external monitor to your laptop and power it up, 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.
Check out www.lcdparts.net for parts, repair service and DIY info.
