No screen image in my laptop

\015 I was playing NFS-U2 so I heard a ''Crack'' sound coming from my laptop, the laptop immediately shuts down. I thought it was nothing because it was the second time in a week it happened. But now it doesn't shows the hp logo at the start up, the sound lights and the fan works, but the screen remains off. My laptop is a Hp 6515b - 1GB ram - Vista Business - ATI graphics 128 MB\015

Answers :

I would agree but only partly so. I think the LCD and the CCLF backlight are okay. It is probably the inverter that is causing the problem. The cracking sound is evidence of this, the backlight is very tough to change by itself and the whole LCD is expensive. First, take the most probably way and buy a replacement inverter, they aren't very expensive. My bet it's all you need.
You may have a defective inverter.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, 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. It could be a faulty inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out; usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
