Do you get any light coming from the display at all? Easiest way to check would be to operate the computer in a pitch black room.

A totally dark display might indicate a broken backlight or backlight inverter (high voltage power supply). Repair can get pricey if the computer is out of warranty.

You might get more help in the Hardware forum. I'll ask a mod to move this topic.

EDIT: I noticed your duplicate post in Hardware:

Hi and welcome to TSG,

I've merged two of your threads here. Please do not start more than one thread for the same problem.

Look at the keyboard and find the Fn key, hold that down while tapping the key with the the round object that looks like sun and has an up arrow. See if that helps.

Here's a picture of them, the Fn key is on the left side of the keyboard, the other is on the right.

Sorry for the delay, thanks for the program & link (quick & easy to download!)
The chipset details are Intel i855GME
I take it the make of the mother board is 'Intel'?
I re-installed the 'chipset' using the 'Drivers & Utilities CD' which came with the laptop,
However I was not sure which other drivers to re-install as well, hence no change in screen color.

Well it sounds like an inverter\backlight problem to me. Its hard to say which one is shot. I have never replaced a backlight but inverters are usually fairly easy to replace if you are good with lots of small screws. Heres a site that sells lamps.

Couldn't you try attaching it to an external screen via the VGA port and seeing if the problem follows onto a working screen?

Yes I have tried attaching it to an external screen and it does work this way! It's just if it's a software problem I would like to try and fix it, and try all possible solutions before taking it to a technician i.e download or re-install software! I have opened up and tried checking the connection but I can't really notice any obvious problems.

Same problem
Afraid to say I appear to have the same problem, I'd like to try that chipset buisness though, except I can't find the right one to download. PC Wizard says my chipset is: "Intel i85xGM" any idea where I can download that? Any help would be greatly appreciated. Thanks.
