I have HP Compaq nx9500 about two years old. Few days back, the lcd went blank and when restarted, started with horizontal stiprs moving up and down. At moments, it clears out and the screen is visible. Also at times, when laptop is powered on its perfectly fine and then in about few minutes, it starts again. Disply in external monitor is fine.

One thing I have noticed is that normally the display is fine for about a second when Welcome screen of Windows appears.

Can anyone help me out in this? What could be the problem. I contacted local HP people (who are not so good in my country) and they asked me to replace the lcd (which is too expensive). Any other alternatives thant this?

Also, is it possible to remove the lcd panel completely and use the base unit as a regular keyboard and cpu with some other external monitor?
