No Display on LCD

Hi,

The problem goes like this. I usually hibernate my system rather than shutting down. As usual today morning I booted my system, everythiwas fine except I was not able adjust the brightness. I "restarted" my Inspiron 6000. No Display at all in my LCD, even at the boot or while booting or after that.

These are what I did so far:

1. I plugged an external mornitor and swtched using Fn+F8. External monitor got the display. No problem at all. But LCD fails and No Display.

2. Removed and reinstalled the RAM and the battery. Still no display

3. Run the Diagnostics [in extended mode]. Reported NO issues.

4. I put my Laptop in a dark room to see any variation in the LCD. When power is up[When pressed the power button], there was some light (indicating the system has some contact with the LCD)

Any help would be greatly appreciated. I was searching the forums from the morning, still I didnt get any valid resolution. Kindly help!!!
