What's your background in electronics? These jobs are usually rather hard to do.

Is the screen still hooked up to a working computer? If so, there are a variety of software implementations you can use to extend your monitor through a network.

If I had to guess, your Hewlett Packard dv9500t is probably suffering from a BGA thermal problem under the Nvidia graphics chip. HP caught a lot of heat (ha!) for it. If true, the fix to re-ball the graphics chip is rather expensive. The cheep fix is to use a re-flow heat gun and "carefully" apply heat to the Nvidia graphics chip. There are plenty of howtos on the web so I'm not going into it here. You might try that before you proceed with the "beheading" :).

-good luck

Thank you st2000 for your answer but I don't want to repair it actually, I have seen a lot of stuff on the re-flow but not really interested in that ... yet. What i m asking is how i can re-use the screen.

Is there some hardware or process to make the screen , i dunno, DVI, HDMI, or VGA .... compatible ?

Thanks !

PS : I hope HP will burn slowly (as my laptop did).

If you know the actual model of the panel, not the laptop, you can usually get a LVDS controller from China via eBay. Such as this one:
http://www.ebay.com/itm/LCD-Controller- ... 19d3ace066

Near as I can tell, that will directly interface with the LCD panel and give it a VGA input. The key thing is to know the actual panel manufacturer and model number. Usually that is obtainable if you take off the plastic laptop housing around the screen.

The problem with rolling your own solution is the intense complexity of doing so. Take a trip 'round Google for the topic you just posted and you'll see that people have been trying to do this for years, without much luck. It seems that these controllers have become available somewhat recently.
