usually, the hardware problem is the inverter board next to the lcd
panel in the lid, what model and type #? if out of warranty and you
feel adventurous, you can try to replace it yourself. Lots of spare
part vendors on Ebay.

Is there any light coming from it at all?

Depending on the model, it is either the inverter or the backlight. On
a 600 series, it is almost always the backlight. On a 770 series, it
is always the inverter.

If it's a burned out CCFL lamp, you can replace it yourself if you are
careful and can use a soldering iron. Your laptop or screen might be
listed here:

If it's the inverter you'll be best finding an exact replacement (eBay,
some laptop components dealers). Google is your friend in this case.
Even if you replace both lamp and inverter it will sill cost hundreds
less than getting a new LCD, but you have to do the work.

Good luck!

I didn't and my screen was pretty dark...as soon as I changed it....wella!  

needs new inverter, simple as that.

I have a T43 with the same issues. I replaced the LCD screen and inverter and still have the problem. I hooked the laptop up to an external monitor and the screen was crystal clear. Any other ideas??
