Pull the battery and unplug it.
Plug in the AC adapter and see if it boots.
if it does shut it down and reinsert battery, problem solved.
if that doesnt do it then i would check that your ram is seated properly and try swapped between 2 ram chips in both sockets (if your laptop has 2 sockets.
Hope this helps!

As you can see the screen with a flashlight then the lcd and video card and cable are fine,
That leave the inverter and the support cable to it.
if you installed another inverter then the lamps are bad, but you have to be certain the inverter is putting out HV, else the support cable and circuit that turn on the inverter is at fault. it is best to trouble shoot in the bios screen , and be certain that you have the brightness turned up.

You could have a defective screen - follow this to determine the fault.
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.
