Presario screen black/power LED on

Hello everybody! I am new to this forum and guess what: I have a problem. The screen on my wife's presario notebook suddenly went black on sunday. She was surfing on the net when that happened. The screen wasn't completely black, it was kinda gray-ish like the LCD light was still on. The power LED was also still on. She turned the notebook off and back on and the screen stayed pitch black. The power LED comes on, the fan is running and also the DVD drive starts running but neither do I see a picture nor does the HDD LED flicker.

I tried different things like unhooking the power, uninstalling the battery but nothing helped. However after a couple of restarts I was able to make it show the 'Compaq' logo twice. Each time the HDD LED flickered a couple of times and then the screen was gray again.

On the Compaq website they suggest to re-set the RAM module(s). Does that sound like a possible solution to anybody? My wife is going to check if the notebook is still under warranty (She bought it in August last year) before I try to mess with the RAM. Does anybody else have any ideas?

Thank you everyone!

 

You need to disassemble the divice and check if the monitor power and data cable is placed correct.

 

Which Compaq? I suspect the usual fried NVIDIA chip...
