General instructions for replacing a Backlight,http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/
Advise: Watch it! On a 1-10 scale of difficulty this rates a 9
Keep all layers EXACTLY as they were. Watch the routing of the cables, and use fresh tape, if the old tape can't be reused.
I would attach the Backlight to it's cable before putting the LCD screen assembly back together. Power the laptop up, and see if the Backlight works, or you have a faulty one.
Make Sure the Backlight you purchased works First! (It's no fun disassembling the LCD screen)
1) Remove ALL power to the laptop. Remove the AC adapter (Charger) and Battery.
2) Observe Anti-Static Precautions.
(Use a $3 ESD wrist strap, and connect it's alligator clip to a good ground source)
3) 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 a multi-compartment container is not available, substitute with a clean egg carton.
Label each egg holder.
Some screws look Very similar to others. They Are Not.
Put a wrong screw in a hole, and not only do you risk the chance of ruining the threads in the hole, and/or on the screw, you also risk the screw becoming stuck halfway in.
Won't screw in any further.Try to remove it, and it may break off.
The LCD screen is part of the Display Assembly.
The Display Assembly needs to be removed from the laptop, in order to access the LCD screen assembly inside it.

It may take additional time for the file to fully download.
Let the file download all the way before looking through it.
(Watch the Download Progress Bar)
At the top of the PDF file is the page number box. It is to the right of the Down Arrow.
Page number for the PDF file, not the Service Manual. (Chapters, and page)
This is the page number I will be referring to, not the Service Manual's page.
Go to Page 145.
Make notes, and/or drawings, (Camera?) of the routing of the Display Cable, Web Camera Cable, and Microphone Cable, before you remove them from the motherboard (System Board) connectors.
They MUST be routed back exactly as they were.
(The connectors are different from each other, so it is easy to see where they go when reassembling)
Watch the routing of the Wireless Antenna Cables.
There are two Philips head screws for each Hinge. (4 total)
Hold onto the Display Assembly securely when you remove these screws.
It's easy to break a Hinge.
There are 6 Philips head screws that hold the Display Bezel on.
The screw heads are under rubber-like screw covers.
The rubber-like screw covers are Gently pried up, with a computer pick on one side.
(Or similar tool)
The screw covers are held on with a type of rubber cement.
If you use care when you set them down, sticky side up, there's a good chance you can reuse them.
(Yes, they do stick to the pick, and your fingers, lol!)
The Display Bezel is the thin plastic 'frame' in front of the LCD screen, and surrounds the LCD screen.
In the manual when it is stated to, "Flex the inside edges of the Left and Right sides, and the Top and Bottom sides of the Display Bezel...........
EASE a fingertip under the middle inside edge of the Left side of the bezel.
Gently pull up a little.
As you do perform the same procedure on the Right side. (Inside edge/Middle)
(When you do you'll hear a snap, snap sound.
This is the tabs releasing from the matching notches.
Kind of unnerving your first time, you may think you are breaking something.
The Display Bezel is made of a space-age plastic, and is pretty tough. Use care, and it won't break)
Do the same for the Top, and Bottom side of the Display Bezel.
Removing the LCD screen assembly is on Page 154.
Disassembling the LCD screen assembly is on Page 278.
