Have a hp laptop. it comes on great and runs well. However if you restart it, it will not load laptop screen. It will work on an external monitor. If you leave it off for 10 minutes it will load screen when you turn it back on.

It looks like your screen is going bad.  If it's still under warranty go that route, otherwise you will have to determine if it's worth the cost of replacing the screen.

You have to contact HP service center it may be an hardware issue (screen got hot due to any lose connection).

Have you tried to check by closing the LED 1~2 times when the screen goes off?

Better to log a complain with HP and let them work on it. If its in warranty.

If it was a systemboard issue, you would have the same behavior with an external monitor attached.

To rule out a software/driver issue try booting with a "live" version of Linux.

http://www.ubuntu.com/download

And see how it behaves.  If it works all day long then you'll know it's software/driver, if it has the same problem you will know for sure it's hardware.

Again as it seems to work fine with an external monitor but has issues when using the built-in LCD I would go with the screen being bad.

Is this system still under warranty?  Also, how old is the system?  Answering these questions will help alot in the advice we will give.

is it a dv 6000, orDV9000 series one?
these are known for heat problems on the video chip

in such a case, cleaning out the laptop from dust is a first start

I agree with nobus.
But shine a bright light at the screen to see if you can see any video it could  be invertor.
Pleas see my article on how to test invertor.
